Claim:
A method for reminding a calendar schedule, suitable for a mobile device, the method comprising: setting a schedule and a location of an event in a calendar, and obtaining first positioning information of the location by using the mobile device; setting a first reminding time of the event in the calendar; obtaining second positioning information of a current location of the mobile device; determining whether to advance the first reminding time based on whether the mobile device is within a signal range of a signal source which provides a connection service for the mobile device at the location, wherein the signal source is either a wireless base station or a Wi-Fi access point; and when determined by the mobile device that the current location exceeds the signal range of the signal source: calculating a transferring time of moving from the current location with the second positioning information to the location of the event with the first positioning information; advancing from the first reminding time to a second reminding time which is earlier than the first reminding time by subtracting the transferring time from the first reminding time to generate the second reminding time; and performing a reminding action of the event at the second reminding time.
