Description:
TECHNICAL FIELD 
     The disclosed embodiments relate generally to calendar applications in electronic devices with touch-sensitive surfaces. More particularly, the disclosed embodiments relate to repositioning a calendar entry within a calendar application on such devices. 
     BACKGROUND 
     The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Such surfaces are widely used to manipulate user interface objects in user interfaces for multifunction devices. 
     For example, while using a calendar application, a user may wish to reposition a user interface object that represents a calendar entry (e.g., an appointment) from its current date/time to a new date/time. Exemplary calendar applications include iCal from Apple, Inc., Outlook from Microsoft, Inc. and Lotus Notes from IBM, Inc. 
     But existing methods for manipulating calendar entries are cumbersome and inefficient. For example, moving a calendar entry from one date/time to another date/time may require manually entering the new date and time in a date/time field or opening two windows where one of the windows displays the current date/time while the other window displays the new date/time. Such manipulations are tedious and create a significant cognitive burden on a user. In addition, conventional methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for quickly and efficiently repositioning calendar entries within a calendar application. Such methods and interfaces may complement or replace existing methods for repositioning calendar entries. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated electronic devices, such methods and interfaces conserve power and increase the time between battery charges.

The keyboard embodiments may include a reduced number of icons (or soft keys) relative to the number of keys in existing physical keyboards, such as that for a typewriter. This may make it easier for users to select one or more icons in the keyboard, and thus, one or more corresponding symbols. The keyboard embodiments may be adaptive. For example, displayed icons may be modified in accordance with user actions, such as selecting one or more icons and/or one or more corresponding symbols. One or more applications on the device may utilize common and/or different keyboard embodiments. Thus, the keyboard embodiment used may be tailored to at least some of the applications. In some embodiments, one or more keyboard embodiments may be tailored to a respective user. For example, one or more keyboard embodiments may be tailored to a respective user based on a word usage history (lexicography, slang, individual usage) of the respective user. Some of the keyboard embodiments may be adjusted to reduce a probability of a user error when selecting one or more icons, and thus one or more symbols, when using the soft keyboard embodiments.

     The audio circuitry  110 , the speaker  111 , and the microphone  113  provide an audio interface between a user and the device  100 . The audio circuitry  110  receives audio data from the peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to the speaker  111 . The speaker  111  converts the electrical signal to human-audible sound waves. The audio circuitry  110  also receives electrical signals converted by the microphone  113  from sound waves. The audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to the peripherals interface  118  for processing. Audio data may be retrieved from and/or transmitted to memory  102  and/or the RF circuitry  108  by the peripherals interface  118 . In some embodiments, the audio circuitry  110  also includes a headset jack (e.g.  212 ,  FIG. 2 ). The headset jack provides an interface between the audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     The I/O subsystem  106  couples input/output peripherals on the device  100 , such as the touch screen  112  and other input/control devices  116 , to the peripherals interface  118 . The I/O subsystem  106  may include a display controller  156  and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input or control devices  116 . The other input/control devices  116  may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)  160  may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG. 2 ) may include an up/down button for volume control of the speaker  111  and/or the microphone  113 . The one or more buttons may include a push button (e.g.,  206 ,  FIG. 2 ). A quick press of the push button may disengage a lock of the touch screen  112  or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) may turn power to the device  100  on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     The touch-sensitive touch screen  112  provides an input interface and an output interface between the device and a user. The display controller  156  receives and/or sends electrical signals from/to the touch screen  112 . The touch screen  112  displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects. 
     A touch screen  112  has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen  112  and the display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on the touch screen  112  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen  112  and the user corresponds to a finger of the user. 
     The touch screen  112  may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen  112  and the display controller  156  may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple, Inc. of Cupertino, Calif. 
     A touch-sensitive display in some embodiments of the touch screen  112  may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, a touch screen  112  displays visual output from the portable device  100 , whereas touch sensitive tablets do not provide visual output. 
     A touch-sensitive display in some embodiments of the touch screen  112  may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     The touch screen  112  may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 160 dpi. The user may make contact with the touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, the device  100  may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     In some embodiments, the device  100  may include a physical or virtual click wheel as an input control device  116 . A user may navigate among and interact with one or more graphical objects (e.g., icons) displayed in the touch screen  112  by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller  160  as well as one or more of the modules and/or sets of instructions in memory  102 . For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen  112  and the display controller  156 , respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen. 
     The device  100  also includes a power system  162  for powering the various components. The power system  162  may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     The device  100  may also include one or more optical sensors  164 .  FIGS. 1A and 1B  show an optical sensor coupled to an optical sensor controller  158  in I/O subsystem  106 . The optical sensor  164  may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor  164  receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module  143  (also called a camera module), the optical sensor  164  may capture still images or video. In some embodiments, an optical sensor is located on the back of the device  100 , opposite the touch screen display  112  on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  may be used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     The device  100  may also include one or more proximity sensors  166 .  FIGS. 1A and 1B  show a proximity sensor  166  coupled to the peripherals interface  118 . Alternately, the proximity sensor  166  may be coupled to an input controller  160  in the I/O subsystem  106 . The proximity sensor  166  may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables the touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     The device  100  may also include one or more accelerometers  168 .  FIGS. 1A and 1B  show an accelerometer  168  coupled to the peripherals interface  118 . Alternately, the accelerometer  168  may be coupled to an input controller  160  in the I/O subsystem  106 . The accelerometer  168  may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. 
     In some embodiments, the software components stored in memory  102  may include an operating system  126 , a communication module (or set of instructions)  128 , a contact/motion module (or set of instructions)  130 , a graphics module (or set of instructions)  132 , a text input module (or set of instructions)  134 , a Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or set of instructions)  136 . 
     The operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     The communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by the RF circuitry  108  and/or the external port  124 . The external port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple, Inc.) devices. 
     The contact/motion module  130  may detect contact with the touch screen  112  (in conjunction with the display controller  156 ) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). The contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module  130  and the display controller  156  detects contact on a touchpad. In some embodiments, the contact/motion module  130  and the controller  160  detects contact on a click wheel. 
     The contact/motion module  130  may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up event. 
     In some embodiments, the contact/motion module  130  ( FIG. 3 ) detects finger gestures, and characterizes the finger gestures to determine whether the finger gestures are associated with specific elements in the user interface (e.g., calendar events) or are part of a multifinger gesture (e.g., a pinching or depinching gesture) for changing the context (e.g., from a single-week view to a multi-week view or from a multi-week view to a single-week view) in an application (e.g., a calendar application) on the multifunction device. 
     The graphics module  132  includes various known software components for rendering and displaying graphics on the touch screen  112  or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like. 
     In some embodiments, the graphics module  132  stores data representing graphics to be used. Each graphic may be assigned a corresponding code. The graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     The text input module  134 , which may be a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     The GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing, to camera  143  as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets). 
     The applications  136  may include the following modules (or sets of instructions), or a subset or superset thereof:
         a contacts module  137  (sometimes called an address book or contact list);   a telephone module  138 ;   a video conferencing module  139 ;   an e-mail client module  140 ;   an instant messaging (IM) module  141 ;   a workout support module  142 ;   a camera module  143  for still and/or video images;   an image management module  144 ;   a video player module  145 ;   a music player module  146 ;   a browser module  147 ;   a calendar module  148 ;   widget modules  149 , which may include weather widget  149 - 1 , stocks widget  149 - 2 , calculator widget  149 - 3 , alarm clock widget  149 - 4 , dictionary widget  149 - 5 , and other widgets obtained by the user, as well as user-created widgets  149 - 6 ;   widget creator module  150  for making user-created widgets  149 - 6 ;   search module  151 ;   video and music player module  152 , which merges video player module  145  and music player module  146 ;   notes module  153 ;   map module  154 ; and/or   online video module  155 .       

     Examples of other applications  136  that may be stored in memory  102  include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

     Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. For example, video player module  145  may be combined with music player module  146  into a single module (e.g., video and music player module  152 ,  FIG. 1B ). In some embodiments, memory  102  may store a subset of the modules and data structures identified above. Furthermore, memory  102  may store additional modules and data structures not described above. 
     In some embodiments, the device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen  112  and/or a touchpad. By using a touch screen and/or a touchpad as the primary input/control device for operation of the device  100 , the number of physical input/control devices (such as push buttons, dials, and the like) on the device  100  may be reduced. 
     The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates the device  100  to a main, home, or root menu from any user interface that may be displayed on the device  100 . In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input/control device instead of a touchpad. 
       FIG. 2  illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen may display one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user may select one or more of the graphics by making contact or touching the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the contact may include a gesture, such as one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with the device  100 . In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap. 
     The device  100  may also include one or more physical buttons, such as “home” or menu button  204 . As described previously, the menu button  204  may be used to navigate to any application  136  in a set of applications that may be executed on the device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI in touch screen  112 . 
     In one embodiment, the device  100  includes a touch screen  112 , a menu button  204 , a push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , a Subscriber Identity Module (SIM) card slot  210 , a head set jack  212 , and a docking/charging external port  124 . The push button  206  may be used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, the device  100  also may accept verbal input for activation or deactivation of some functions through the microphone  113 . 
       FIG. 3  is a block diagram of an exemplary computing device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, the device  300  is a laptop computer, a desktop computer, a table computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). The device  300  typically includes one or more processing units (CPU&#39;s)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. The communication buses  320  may include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. The device  300  includes an input/output (I/O) interface  330  comprising a display  340 , which is typically a touch screen display  112 . The I/O interface  330  also may include a keyboard and/or mouse (or other pointing device)  350  and a touchpad  355 . Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and may include non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  may optionally include one or more storage devices remotely located from the CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in the memory  102  of portable multifunction device  100  ( FIG. 1 ), or a subset thereof. Furthermore, memory  370  may store additional programs, modules, and data structures not present in the memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  may store drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG. 1 ) may not store these modules. 
     Each of the above identified elements in  FIG. 3  may be stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory  370  may store a subset of the modules and data structures identified above. Furthermore, memory  370  may store additional modules and data structures not described above.

     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on a computing device with a display and a touch-sensitive surface, such as device  300  or portable multifunction device  100 . 
       FIGS. 5A-5Q  illustrate exemplary user interfaces for repositioning calendar entries in a calendar application in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below with respect to  FIGS. 6A-6D  and  7 A- 7 B. 
       FIGS. 5A-5B  illustrate the device responding to detection of a first user input (e.g., via cursor  5002 ) by selecting a calendar entry (e.g.,  5004 ) and moving  5006  the calendar entry. 
       FIGS. 5B-5F  illustrate the device responding to detection of a multifinger gesture by expanding display of a single week in the multi-week view. 
       FIGS. 5F-5H  illustrate the device horizontally scrolling the display of the single-week view in the calendar in response to a finger gesture. 
       FIGS. 5H-5J  illustrate the device vertically scrolling the display of the single-week view in the calendar in response to a finger gesture. 
       FIGS. 5J-5K  illustrate the device moving the first calendar entry  5004  to a new date/time in the calendar application in accordance with a second input (e.g., movement  5026  and a subsequent mouse up) by the user. 
       FIGS. 5L-5P  illustrate the device responding to a first user input that includes finger contacts with a plurality of calendar entries by selecting the calendar entries (e.g.,  5004  and  5005 ), moving the calendar entries in accordance with the movement of the contacts, and, while continuing to detect selection of the calendar entries by the user, detecting a multifinger gesture on the touch-sensitive surface and replacing display of the single-week view with display of a multi-week view in the calendar application. 
       FIG. 5Q  illustrates the device detecting a first user input and a multifinger gesture on a touch-sensitive surface that corresponds to, but is separate from, a display that includes one or more calendar entries and a calendar application. 
       FIGS. 6A-6D  are flow diagrams illustrating a method  600  of repositioning calendar entries within a calendar application in accordance with some embodiments. The method is performed at a multifunction device (e.g.,  100  or  300 ) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display (e.g.,  340  in  FIG. 5A ) and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface, as described in greater detail below with reference to  FIG. 5Q . 
     As described below, the method  600  provides an intuitive way to manipulate one or more calendar entries in a calendar application using a touch-sensitive surface. A simple multifinger gesture is used to transition between a multi-week view (e.g., a monthly view) and a single week in the multi-week view while manipulating the calendar entries. The method reduces the cognitive burden on a user when repositioning one or more calendar entries in the calendar application, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manipulate a calendar entry in a calendar application faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 602 ) a multi-week view in a calendar application on the display. In some embodiments, the multi-week view is ( 604 ) a monthly view. For example, in  FIG. 5A , the month of August 2008 is displayed, including four full weeks and two partial weeks. 
     The device detects ( 606 ) a first input by a user. In some embodiments, the first input by the user is ( 608 ) a mouse-based input (e.g., a mouse click while the cursor  5002  in  FIG. 5A  is on the calendar entry A  5004  in  FIG. 5A ). In some embodiments, the first input by the user is ( 610 ) a finger-based input (e.g., a finger contact on the touch sensitive surface at a location on the touch sensitive surface that corresponds to the first calendar entry, as described in greater detail below with reference to  FIGS. 5L-5P ). 
     In response to detecting the first input by the user, the device selects ( 612 ) a first calendar entry (e.g.,  5004  in  FIG. 5A ) in the multi-week view in the calendar application. 
     Operations  616 - 660  are performed while continuing ( 614 ) to detect selection of the first calendar entry (e.g.,  5004  in  FIG. 5A ) by the user. In other words, the manipulations in the calendar application described below are performed while the calendar entry is selected by the user. For example, as described in greater detail below, after selecting a calendar entry, the device shifts the context in the calendar application in response to detecting a multifinger gesture (e.g., the device shifts from a multi-week view of the calendar application to a single-week view of the calendar application and/or shifts from a first week view to a second week view) while the calendar entry remains selected. 
     In some embodiments, the first input by the user includes a selection of the calendar entry (e.g.,  5004  in  FIG. 5A ) and a movement of the cursor or finger contact (e.g.,  5006  in  FIG. 5A ). In response to the movement of the cursor or finger contact, the device moves the selected calendar entry (e.g., calendar entry A  5004  in  FIG. 5A ) in accordance with the movement of the cursor or finger. For example, in  FIG. 5B  calendar entry A  5004  has been moved from its initial location ( 5004  in  FIG. 5A ) to a new location ( 5004  in  FIG. 5B ) in the lower right hand corner of the display. In some embodiments one or more additional distinct calendar entries (e.g., calendar entry B  5005  in  FIG. 5A ) are also displayed in the multi-week view. 
     The device detects ( 616 ) a first multifinger gesture on the touch-sensitive surface (e.g., detection of contacts  5008  and  5010  and their movement in  FIGS. 5B-5D ). In some embodiments, the first multifinger gesture is detected ( 618 ) by the device on the touch-sensitive surface at a location on the touch-sensitive surface that corresponds to the multi-week view in the calendar application. In some embodiments, the first multifinger gesture is ( 620 ) a two-finger depinching gesture. For example, the device detects contacts  5008 - 1  and  5010 - 1  and subsequent movement of the contacts apart from each other (e.g., movement  5012  of a first contact  5008  from a first location  5008 - 1  in  FIG. 5B  to second location  5008 - 2  in  FIG. 5C  and movement  5014  of second contact  5010  from a first location  5010 - 1  in  FIG. 5B  to a second location  5010 - 2  in  FIG. 5C ). In some embodiments the depinching gesture includes the movement of one of the contacts but not the other contact, but is still determined by the device to be a depinching gesture because the contacts move farther apart from each other. Continuing the example described above, in  FIGS. 5C and 5D , contact  5008  moves  5016  from the second location  5008 - 2  in  FIG. 5C  to a third location  5008 - 3  in  FIG. 5D , while contact  5010  remains in the second location  5010 - 2 . 
     In response to detecting the first multifinger gesture on the touch-sensitive surface, the device expands ( 622 ) display of a single week in the multi-week view and maintains display of the first calendar entry on the display. In some embodiments, expanding display of the single week in the multi-week view comprises displaying ( 624 ) an animation of a transition from the multi-week view to a single-week view. In some embodiments the animation includes stretching the visual representation of the week in a direction in accordance with the depinching gesture. For example, in  FIG. 5C , the row that is a visual representation of the week of August 24 is stretched so that it is taller than the visual representations of other weeks (e.g., the visual representation of the week behaves as if it were printed on a thin rubber sheet, which is being stretched in a vertical direction by the depinching gesture). Thus, in this example, calendar entry B (e.g.,  5005  in  FIGS. 5B-5C ) moves from a first location (e.g.,  5005  in  FIG. 5B ) to a second location ( 5005  in  FIG. 5C ) as the visual representation of the week is stretched by the device. 
     In some embodiments, the animation additionally includes replacing the display of a stretched visual representation of a week with a visual representation of detailed calendar entries for the week. For example, in  FIG. 5D , the stretched visual representation of the week of August 24th (as shown in  FIG. 5C ) is replaced with a visual representation of detailed calendar entries. Thus, in this example, a compact visual representation of calendar entry B (e.g.,  5005  in  FIG. 5C ) is replaced with a detailed visual representation of calendar entry B (e.g.,  5005  in  FIG. 5D ), where the detailed visual representation of calendar entry B includes more information about the calendar entry than the compact visual representation (e.g., a representation of approximate start and end times, a location and/or a list of participants in the event indicated by the calendar entry) . In some embodiments, the single week that is expanded is the single week (e.g., the week of August 24th in  FIG. 5B ) in the multi-week view that the first calendar entry (e.g., calendar entry A  5004  in  FIG. 5B ) is displayed ( 626 ) over when the first multifinger gesture is detected. It should be understood that in some embodiments instead of being displayed over the single week, the first calendar entry is displayed on, or within the single week. Additionally, in some embodiments, the single week that is expanded is a single week in the multi-week view that is proximate to the multifinger gesture (e.g., a week that contains one or both of the initial contacts for a depinching gesture). 
     In some embodiments, the device expands display of the single week in the multi-week view by replacing ( 630 ) display of the multi-week view with display of a single-week view in the calendar application. For example, in  FIG. 5D  the device detects a lift off of the contacts (e.g.,  5008 - 3  and  5010 - 2 ) which performed the multifinger gesture (e.g., the depinching gesture) and in  FIGS. 5E-5F , the device displays an animation replacing the multi-week view with a single-week view. In some embodiments, the animation replacing the multi-week view with a single-week view includes expanding the detailed calendar entries and shifting the detailed calendar entries so that the single-week view completely replaces the multi-week view (e.g., takes up substantially all of the space that was previously taken up by the multi-week view). For example, in  FIGS. 5D-5F , calendar entry B  5005  shifts upwards on the display from a first location (e.g.,  5005  in  FIG. 5D ) to a second location (e.g.,  5005  in  FIG. 5E ) to a third location (e.g.,  5005  in  FIG. 5F ). Similarly, it should be understood that in some embodiments the selected calendar entry (e.g., calendar entry A  5004 ) does not move as part of the animation. Rather, in some embodiments, the selected calendar entry only moves when the cursor or finger contact that is associated with the selected calendar entry moves. For example, in  FIGS. 5D-5F , the cursor does not move and thus calendar entry A  5004  does not move from its location, even though the multi-week view is being stretched by the device to display a single-week view. However, it should be understood that, in this example, if the cursor or contact were to move, the selected calendar entry (e.g., calendar entry A  5004 ) would move independently of the animation of replacing the multi-week view with a single week-view. 
     In some embodiments, while displaying the single-week view in the calendar application and while continuing to detect selection of the first calendar entry by the user, the device detects ( 632 ) a finger gesture on the touch-sensitive surface. In response to detecting the finger gesture on the touch-sensitive surface, the device scrolls ( 634 ) the display of the single-week view in the calendar. In some embodiments, the finger gesture is ( 636 ) a horizontal swipe gesture and the single-week view is scrolled horizontally in one-week increments in response to the horizontal swipe gesture. For example, in  FIGS. 5F-5H , the device detects a contact  5018  with the touch screen followed by a horizontal swipe gesture (e.g., movement  5020  of the contact towards the right side of the touch screen). In response to the single horizontal swipe, the device scrolls the single-week view in a one week increment (e.g., the week of August 24th is replaced with the week of August 17th).  FIG. 5G  illustrates an animation of the scrolling of a one week increment, where the currently displayed week (e.g., the week displayed in  FIG. 5F ) is replaced with a new week (e.g., the week in  FIG. 5H ) by simultaneously scrolling the current week off of the right side of the touch screen while scrolling the new week on from the left side of the touch screen (e.g., the animation is as if the first week and the second week are printed on one continuous piece of paper which is being pulled off the right side of the touch screen). Similarly, as described in greater detail above, it should be understood that in some embodiments the selected calendar entry (e.g., calendar entry A  5004 ) does not move as part of the animation. By not moving the selected calendar entry (e.g., calendar entry A  5004  in  FIG. 5G ) as part of the animation, the device allows the user to move the calendar entry to a new date/time simply by holding the calendar entry in a fixed location while simultaneously shifting the context of the single-week view. 
     In some embodiments, the finger gesture is ( 638 ) a vertical swipe gesture and the single-week view is scrolled vertically in one-week increments in response to the vertical swipe gesture. For example, in  FIGS. 5H-5J , the device detects a contact  5022  with the touch screen followed by a vertical swipe gesture (e.g., movement  5024  of the contact towards the top of the touch screen), and in response to the single vertical swipe, the device scrolls the single-week view in a one week increment (e.g., the week of August 17th is replaced with the week of August 24th).  FIG. 5I  illustrates an animation of the scrolling of a one week increment, where the currently displayed week (e.g., the week displayed in  FIG. 5H ) is replaced with a new week (e.g., the week in  FIG. 5J ) by simultaneously scrolling the current week off of the top of the touch screen while scrolling the new week on from the bottom of the touch screen (e.g., the animation is as if the first week and the second week are printed on one continuous piece of paper which is being pulled off the top of the touch screen). In this example, calendar entry B  5005  is scrolled back onto the screen. During the animation, calendar entry B  5005  is at current location (e.g.,  5005  in  FIG. 5I ) and at the end of the animation, calendar entry B returns to its previous location (e.g.,  5005  in  FIG. 5J  is the same location as  5005  in  FIG. 5F ). Similarly, as described in greater detail above, it should be understood that in some embodiments the selected calendar entry (e.g., calendar entry A  5004  in  FIGS. 5F-5J ) does not move as part of the animation. By not moving the selected calendar entry (e.g.,  5004  in  FIG. 5I ) as part of the animation, the device allows the user to move the calendar entry to a new date/time by holding the calendar entry in a fixed location while simultaneously shifting the context of the single-week view. 
     In some embodiments, while displaying the single-week view in the calendar application and while continuing to detect selection of the first calendar entry by the user, the device detects ( 640 ) a second multifinger gesture on the touch-sensitive surface. In some embodiments, the second multifinger gesture is ( 642 ) a gesture that is the opposite (or substantially the opposite) of the first multifinger gesture. 
     In some embodiments, the second multifinger gesture is ( 644 ) a two-finger pinching gesture. For example, the device detects contacts  5036 - 1  and  5038 - 1  and subsequent movement of the contacts towards each other (e.g., movement  5040  of a first contact  5036  from a first location  5036 - 1  in  FIG. 5M  to second location  5036 - 2  in  FIG. 5N  and movement  5042  of second contact  5038  from a first location  5038 - 1  in  FIG. 5M  to a second location  5038 - 2  in  FIG. 5N ). In some embodiments the pinching gesture includes the movement of one of the contacts but not the other contact, but is still a pinching gesture because the contacts move closer together. Continuing the example described above, in  FIGS. 5N and 5O , contact  5036  moves  5044  from the second location  5036 - 2  in  FIG. 5N  to a third location  5036 - 3  in  FIG. 5O , while contact  5038  remains at the second location  5038 - 2 . 
     In some embodiments, in response to detecting the second multifinger gesture on the touch-sensitive surface, the device replaces ( 646 ) display of the single-week view with display of a multi-week view in the calendar application, and maintains display of the first calendar entry (e.g.,  5004  in  FIG. 5O ) on the display. In some embodiments, replacing display of the single-week view with display of the multi-week view comprises displaying ( 648 ) an animation of a transition from the single-week view to a multi-week view. In some embodiments the animation is the reverse of the animation of a transition from the multi-week view to the single-week view. For example, the visual representation of the single week in the single-week view is visually compressed as shown in  FIG. 5N . In this example, the visually compressed representation of the single week is replaced with a less detailed (e.g., compact) view of the calendar entries in the single-week view along with a less detailed (e.g., compact) view of the calendar entries for adjacent weeks, as shown in  FIG. 5O . 
     In some embodiments, the device detects ( 650 ) a second input by the user. In response to detecting the second input by the user, the device moves ( 660 ) the first calendar entry to a date/time in the calendar application in accordance with a second input by the user. 
     In some embodiments, the second input by the user is ( 652 ) a mouse-based input (e.g., a mouse drag followed by a mouse up while the cursor is on the first calendar entry). In some embodiments, the second input by the user is ( 654 ) a continuation of the first input. For example, the first input is a mouse click while the cursor is on the first calendar entry and the second input is a mouse drag (to move/position the first calendar entry in the single week) and a mouse up (to place/release the first calendar entry in the single week), as shown in  FIGS. 5J-5K . For example, in  FIG. 5J , the device detects a mouse drag movement  5026  of calendar entry A  5004 , and the device moves the calendar entry A from a first location (e.g.,  5004  in  FIG. 5J ) which represents a first date/time in the single week to a second location (e.g.,  5004  in  FIG. 5K ) which represents a second date/time in the single week. In this example, the device detects a mouse up command from the user and in response releases calendar entry A in a new location (e.g.,  5004  in  FIG. 5K ) which represents a new date/time in the single week. It should be understood that a similar movement can also be used to move a calendar entry from a first calendar context (e.g., a single-week view or multi-week view) to a second calendar context (e.g., a single-week view or multi-week view) that is distinct from the first calendar context. 
     In some embodiments, the second input by the user is ( 656 ) a finger-based input (e.g., a finger movement on the touch-sensitive surface and a finger lift off). In some embodiments, the second input by the user is ( 658 ) a continuation of the first input. For example, the first input is a finger contact (e.g.,  5028 - 1  in  FIG. 5L ) on the touch sensitive surface at a location on the touch sensitive surface that corresponds to the first calendar entry (e.g., calendar entry A  5004  in  FIG. 5L ) and the second input is a finger movement (e.g.,  5030  in  FIG. 5L and 5046  in  FIG. 5O ) on the touch-sensitive surface (to move/position the first calendar entry in the single week) and a finger lift off (to place/release the first calendar entry in the single week), as described below in greater detail with reference to  FIGS. 5L-5P . 
     It should be understood that the second input described above may be detected either before the second multifinger gesture is detected or after the second multifinger gesture is detected. In other words, in some embodiments the calendar entry is moved to a date/time in a single-week view of the calendar application, while in other embodiments the calendar entry is moved to a date/time in a multi-week view of the calendar application. Similarly, in some embodiments the calendar entry is initially selected in a multi-week view of the calendar application, while in other embodiments the calendar entry is initially selected in a single-week view of the calendar application. 
     As one example of moving a calendar entry, the calendar entry is selected in a multi-week view and moved to a date/time in a single-week view of the calendar application by selecting the calendar entry in the multi-week view, switching to the single-week view using any of the methods for switching from a multi-week view to a single-week view discussed above with reference to  FIGS. 5B-5F  and then placing the calendar entry in the second single-week view. As another example of moving a calendar entry, the calendar entry is selected in a first single-week view and moved to a date/time in a distinct second single-week view of a calendar application by selecting the calendar entry in the first single-week view, switching to the second single-week view using any of the methods for switching between two single-week views discussed above with reference to  FIGS. 5F-5K  and then placing the calendar entry in the second single-week view. As another example of moving a calendar entry, the calendar entry is selected in a single-week view and moved to a date/time in a multi-week view of a calendar application by selecting the calendar entry in the single-week view, switching to the multi-week view using any of the methods for switching from a single-week view to a multi-week view discussed above with reference to  FIGS. 5M-5P  and then placing the calendar entry in the multi-week view. It should be understood that the preceding examples are merely illustrative of combinations of multi-finger gestures with other inputs while continuing to detect the selection of a calendar event. 
     In another example, multiple multi-finger gestures to move a calendar entry from a first single-week view to a second single-week view. In this example, the following steps are performed, in order: a calendar entry is selected in a single-week view of Week A (e.g., by a finger contact with the calendar entry); a pinching gesture is detected; a multi-week view is displayed, which includes simultaneously displaying a representation of Weeks A and B; a depinching gesture on a different week (Week B) is detected; a single-week view of Week B is displayed; a second user input is detected (e.g., liftoff of the finger contact with the calendar entry), and in response the calendar entry is placed in Week B (e.g., the date/time of the calendar entry is changed so that the calendar entry has a date/time within Week B). 
     Additionally, while the preceding examples have been given with reference to moving a single calendar entry, it should be understood that in some embodiments a plurality of calendar entries are moved simultaneously. In particular, in some embodiments, while a single first calendar entry is selected, a second calendar entry is also selected by the device in response to detecting a user input associated with the second calendar entry (e.g., a finger contact with the calendar entry or a mouse click on the calendar entry). It should be understood that when the first input includes gestures associated with a plurality of calendar entries (e.g., calendar entry A  5004  and calendar entry B  5005 ) the second input may include either an input associated with one of the calendar entries or an input associated with more than one of the plurality of calendar entries. One example of moving a plurality of calendar entries simultaneously is described in greater detail below with reference to  FIGS. 5L-5P . 
     As an example of moving a plurality of calendar entries simultaneously, in  FIG. 5L  the device detects a contact  5028 - 1  with calendar entry A  5004  and a distinct contact  5032 - 1  with calendar entry B  5005  on a touch screen that is displaying a calendar application in a single-week view. The device detects movement (e.g.,  5030  and  5034  in  FIG. 5L ) of each of the contacts to a new location on the touch screen (e.g.,  5028 - 2  and  5032 - 2  in  FIG. 5M ) and in response moves the associated calendar entries to new locations (e.g.,  5004  and  5005  in  FIG. 5M ). In some embodiments, each of the contacts moves independently of the other contacts and thus the calendar entry associated with that contact moves independently of the movement of the other calendar entries. While detecting movement of the contacts, the device detects a multifinger gesture (e.g., contacts  5036 - 1  and  5038 - 1  and respective movement  5040  and  5042  of each of the contacts in a pinching gesture as described in greater detail above with reference to  FIGS. 5M-5O ). In response to detecting the multifinger gesture (and while continuing to detect the selection of calendar entry A  5004  and calendar entry B  5005 ), the device shifts from the single-week view to a multi-week view as shown in  FIGS. 5M-5O . In this example, the device also detects movement (e.g.,  5046  and  5048 ) of the contacts (e.g.,  5028 - 2  and  5032 - 2 ) associated with calendar entry A  5004  and calendar entry B  5005  to a current location (e.g.,  5028 - 3  and  5032 - 3  respectively in  FIG. 5P ). In response to detecting the movement of the contacts, the device moves the calendar entries (e.g.,  5004  and  5005  in  FIG. 5O ) to new locations on the touch screen. In this example, calendar entry A moves to a new location (e.g.,  5004  in  FIG. 5P ) associated with August 19th, while calendar entry B moves to a new location (e.g.,  5005  in  FIG. 5P ) associated with August 11th. If the device detects a release of either of these contacts, the date/time of the calendar entry associated with the contact will be changed to match a date/time associated with the current location of the calendar entry that was associated with the released contact (e.g., calendar entry A would be associated with August 19th, while calendar entry B would be associated with August 11th). 
     Additionally, although the preceding examples have been given with reference to a touch screen display, in some embodiments the display and the touch-sensitive surface are separate, as shown in  FIG. 5Q . For example, in  FIG. 5Q , the display  340  and the touch-sensitive surface (e.g., track pad  355 ) are separate. In some embodiments the touch sensitive surface  355  has a primary axis (e.g.,  5054  in  FIG. 5Q ) that corresponds to a primary axis (e.g.,  5056  in  FIG. 5Q ) on the display  340 . In accordance with these embodiments, the device detects a plurality of contacts (e.g.,  5058 ,  5060 ,  5062 ,  5064  in  FIG. 5Q ) with the touch-sensitive surface at locations that correspond to respective locations on the display (e.g., in  FIG. 5Q   5058  corresponds to  5066 ,  5060  corresponds to  5068 ,  5062  corresponds to  5070 , and  5064  corresponds to  5072 ). The device detects a first user input (e.g.,  5062  and/or  5064 ) on the touch sensitive surface, which corresponds to one or more calendar entries (e.g., calendar entry C  5074  and/or calendar entry D  5076  in  FIG. 5Q ) in the calendar application on the display (e.g.,  340  in  FIG. 5Q ). While continuing to detect the first user input, the device detects a first multifinger gesture on the touch-sensitive surface at a location that corresponds to a multifinger gesture on the display. For example, a pinching gesture including movement (e.g.,  5078  and  5080 ) of at least two of the contacts (e.g.,  5058  and  5060 ) on the touch-sensitive surface towards each other corresponds to a pinching gesture including corresponding movement (e.g.,  5082  and  5084 ) of corresponding contacts (e.g.,  5066  and  5068 ) on the display towards each other. In this way, user inputs detected by the device on the touch-sensitive surface (e.g., trackpad  355  in  FIG. 5Q ) are used by the device to manipulate the calendar application on the display (e.g.,  5050  in  FIG. 5Q ) of the multifunction device when the touch-sensitive surface  355  and the display  340  are separate. 
       FIGS. 7A-7B  are flow diagrams illustrating a method  700  of replacing a multi-week view with a single-week view in a calendar application in accordance with some embodiments. The method is performed at a multifunction device (e.g.,  100  or  300 ) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display (e.g.,  340  in  FIG. 5A ) and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface, as described in greater detail above with reference to  FIG. 5Q . 
     As described below, the method  700  provides an intuitive way to change calendar views using a touch-sensitive surface. A simple multifinger gesture is used to transition between a multi-week view (e.g., a monthly view) and a single week in the multi-week view. The method reduces the cognitive burden on a user when changing views in the calendar application, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to change views in a calendar application faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 702 ) a multi-week view in a calendar application on the display. In some embodiments, the multi-week view is ( 704 ) a monthly view (e.g., in  FIG. 5A  the month of August  2008  is displayed, including a plurality of weeks). The device detects ( 706 ) a first multifinger gesture on the touch-sensitive surface. In some embodiments, the first multifinger gesture is ( 708 ) detected on the touch-sensitive surface at a location on the touch-sensitive surface that corresponds to the multi-week view in the calendar application. In some embodiments, the first multifinger gesture is ( 710 ) a two-finger depinching gesture (e.g., the depinching gesture of contacts  5008  and  5010  as described in greater detail above with reference to  FIGS. 5B-5D ). 
     In response to detecting the first multifinger gesture on the touch-sensitive surface, the device replaces ( 712 ) display of the multi-week view with display of a single-week view in the calendar application. In some embodiments, replacing display of the multi-week view with display of the single-week view in the calendar application comprises displaying ( 714 ) an animation of a transition from the multi-week view to the single-week view (e.g., as described in greater detail above with reference to  FIGS. 5B-5D ). 
     In some embodiments operations  718 - 734  are performed while displaying ( 716 ) the single-week view in the calendar application. The device detects ( 718 ) a finger gesture on the touch-sensitive surface. In response to detecting the finger gesture on the touch-sensitive surface, the device scrolls ( 720 ) the display of the single-week view in the calendar. In some embodiments, the finger gesture is a horizontal swipe gesture (e.g., a contact  5018  and movement  5020  of the contact in a horizontal direction on the display as shown in  FIG. 5F ) and the single-week view is scrolled horizontally ( 722 ) in one-week increments in response to the horizontal swipe gesture (e.g., as described in greater detail above with reference to  FIGS. 5F-5H ). In some embodiments, the finger gesture is a vertical swipe gesture (e.g., a contact  5022  and movement  5024  of the contact in a vertical direction on the display in  FIG. 5H ) and the single-week view is ( 724 ) scrolled vertically in one-week increments in response to the vertical swipe gesture (e.g., as described in greater detail above with reference to  FIGS. 5H-J ). 
     In some embodiments, while displaying the single-week view in the calendar application the device detects ( 726 ) a second multifinger gesture on the touch-sensitive surface. In some embodiments, the second multifinger gesture is ( 728 ) a gesture that is the opposite (or substantially the opposite) of the first multifinger gesture. In some embodiments, the second multifinger gesture is ( 730 ) a two-finger pinching gesture (e.g., the pinching gesture of contacts  5036  and  5038  as described in greater detail above with reference to  FIGS. 5M-5O ). 
     In some embodiments, in response to detecting the second multifinger gesture on the touch-sensitive surface, the device replaces ( 732 ) display of the single-week view with display of a multi-week view in the calendar application (e.g., as shown in when the user interface in  FIG. 5M  is replaced with the user interface in  FIG. 5P , as described in greater detail above with reference to these Figures). In some embodiments, replacing display of the single-week view with display of the multi-week view comprises displaying ( 734 ) an animation of a transition from the single-week view to a multi-week view (e.g., as described in greater detail above with reference to  FIGS. 5M-5O ). 
     Additionally, although the preceding examples have been given with reference to a touch screen display, it should be understood that in some embodiments the display and the touch-sensitive surface are separate, as described in greater detail above with reference to  FIG. 5Q . 
     The steps in the information processing methods described above may be implemented by running one or more functional modules in information processing apparatus such as general purpose processors or application specific chips. These modules, combinations of these modules, and/or their combination with general hardware (e.g., as described above with respect to  FIGS. 1A ,  1 B and  3 ) are all included within the scope of protection of the invention. 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
