A method and an apparatus for reminding a calendar schedule and a recording medium are provided. First, a schedule and a location of an event are set in a calendar, and first positioning information of the location is obtained. Then, second positioning information of a current location of a mobile device is obtained. Next, the current location is determining whether to be within a signal range of a signal source. Once the current location is within the signal range, the time for moving from the location with the second positioning information to the location with the first positioning information is calculated. Finally, a reminding time is set according to the transferring time, and a reminding action is taken at the reminding time. Thereby, the reminding time of the event can be dynamically adjusted to avoid delay caused when the mobile device is too far from the event location.
