A method, comprising: at an electronic device with a touch-sensitive display, wherein the touch-sensitive display comprises one or more sensors to detect characteristic intensity of contacts with the touch-sensitive display: displaying, on the display, a calendar application that includes a plurality of calendar affordances representing a plurality of calendar events, wherein the plurality of calendar affordances are displayed with a first calendar arrangement; detecting a first touch on the display, the first touch having a characteristic intensity, the first touch located at an area of the display corresponding to a first calendar affordance from the plurality of calendar affordances representing a plurality of calendar events; determining whether the characteristic intensity of the first touch is above a threshold intensity; in response to a determination that the characteristic intensity of the touch is above the threshold intensity: ceasing to display the calendar application that includes the plurality of calendar affordances representing the plurality of calendar events, wherein the plurality of calendar affordances are displayed with the first calendar arrangement; and displaying, on the touch-sensitive display, a plurality of affordances representing a plurality of calendar arrangements; while displaying the plurality of affordances representing a plurality of calendar arrangements, detecting a second touch on the display located at an area of the display corresponding to one affordance from the plurality of affordances representing a plurality of calendar arrangements; and in response to detecting the second touch: ceasing to display the plurality of affordances representing the plurality of calendar arrangements; and displaying, on the display, the calendar application with the plurality of calendar affordances representing the plurality of calendar events, wherein the plurality of calendar affordances are displayed with a second calendar arrangement different from the first calendar arrangement; and in accordance with a determination that the characteristic intensity of the first touch is below the threshold intensity: displaying additional information associated with a calendar event corresponding to the first calendar affordance from a plurality of calendar affordances. displaying, on the display, a calendar application that includes a plurality of calendar affordances representing a plurality of calendar events, wherein the plurality of calendar affordances are displayed with a first calendar arrangement; detecting a first touch on the display, the first touch having a characteristic intensity, the first touch located at an area of the display corresponding to a first calendar affordance from the plurality of calendar affordances representing a plurality of calendar events; determining whether the characteristic intensity of the first touch is above a threshold intensity; in response to a determination that the characteristic intensity of the touch is above the threshold intensity: ceasing to display the calendar application that includes the plurality of calendar affordances representing the plurality of calendar events, wherein the plurality of calendar affordances are displayed with the first calendar arrangement; and displaying, on the touch-sensitive display, a plurality of affordances representing a plurality of calendar arrangements; ceasing to display the calendar application that includes the plurality of calendar affordances representing the plurality of calendar events, wherein the plurality of calendar affordances are displayed with the first calendar arrangement; and displaying, on the touch-sensitive display, a plurality of affordances representing a plurality of calendar arrangements; while displaying the plurality of affordances representing a plurality of calendar arrangements, detecting a second touch on the display located at an area of the display corresponding to one affordance from the plurality of affordances representing a plurality of calendar arrangements; and in response to detecting the second touch: ceasing to display the plurality of affordances representing the plurality of calendar arrangements; and displaying, on the display, the calendar application with the plurality of calendar affordances representing the plurality of calendar events, wherein the plurality of calendar affordances are displayed with a second calendar arrangement different from the first calendar arrangement; and ceasing to display the plurality of affordances representing the plurality of calendar arrangements; and displaying, on the display, the calendar application with the plurality of calendar affordances representing the plurality of calendar events, wherein the plurality of calendar affordances are displayed with a second calendar arrangement different from the first calendar arrangement; and in accordance with a determination that the characteristic intensity of the first touch is below the threshold intensity: displaying additional information associated with a calendar event corresponding to the first calendar affordance from a plurality of calendar affordances.
