Abstract: Providing a contextual reminder to a mobile station includes determining a locus of the mobile station based on the position of the mobile station in both time and space. A first entry is read, where the first entry can be at least a task or an event. Both tasks and events can include a time, a date, and/or a location. The locus and the first entry can be compared to determine if the contextual reminder should be provided to the mobile station. The contextual reminder can be provided to the mobile station based on the comparison. The reminder can be provided when at least one of the time, the date and the geographical position of the mobile station is proximate to at least one of the time, date, and location of the entry.
