Abstract: A method includes receiving a scheduling event at a calendar application from a user, where the scheduling event includes at least an identification of a task and an amount of time needed to complete the task; monitoring a calendar of the user with the calendar application to identify an unscheduled period of time having a duration at least equal to the time needed to complete the task; and notifying the user of an identified unscheduled period of time having the duration at least equal to the time allocated to complete the task. In the method the scheduling event may further comprise an identification of a period of time in which to complete the task.

Abstract: In one exemplary aspect the invention includes a method that operates by receiving an invitation to create a calendar event from an originating calendar application at a recipient calendar application, the invitation comprising at least one calendar event parameter; comparing by the recipient calendar application the at least one received calendar event parameter to a set of local calendar event parameters at the recipient calendar application and one of automatically replying with an acceptance of the invitation or a rejection of the invitation based on the comparison, where an acceptance of the invitation comprises creating a new calendar event in a user's calendar that is managed by the recipient calendar application.

Abstract: In one non-limiting aspect the exemplary embodiments provide a method that includes, in response to a user-generated input, operating a calendar application to access an electronic calendar to cancel at least one scheduled event; and generating information for use in contacting at least one party associated with the cancelled at least one scheduled event. The calendar application may also re-schedule the cancelled at least one event in the electronic calendar. The user-generated signal may result form the user activating a calendar interrupt function to automatically clear and re-schedule calendar events.

Abstract: A method includes sending a proposed event from an originating calendar application to a recipient calendar application, and one of replying with an approval of the proposed event or a modification to the proposed event from the recipient calendar application to the originating calendar application. Also disclosed are computer program products and devices that include calendar application(s) that operate as in the method.
