A system for the display and editing of scheduled tasks and timeslots represented in the form of user interface elements embedded in the calendar regions of the graphical user interface of electronic calendaring systems. It provides structures and methods for editing schedule data in the form of individual tasks and timeslots, sub-groups of tasks and timeslots, and related collections of scheduled tasks and timeslots. It provides for the automated generation of scheduled tasks and timeslots information using a template structure, thereby reducing the amount of decisions and key strokes required for the user to generate and load into their personal calendars a predefined program of recurring tasks and timeslots. Methods are employed to minimize routine program maintenance requirements. In particular, a structure is provided which allows scheduled tasks information to be defined in such a way that particular tasks may be added or removed from a user's schedule either after predefined intervals of time, or, dynamically in response to changes in a predefined metric such as might be used to measure a user's skill level or efficiency.
