Abstract

An electronic calendar is provided for displaying time of the day, day of the week, and month-date-year with automatic adjustments for leap years and changes to and from standard and daylight times. The electronic calendar also displays preprogrammed and user programmed information such as holidays, holy days, birthdays, anniversaries, appointments, horoscopes, and other messages. In addition, the electronic calendar incorporates a method for randomly selecting and displaying programmed messages, such as advertisements and safety slogans, at recurring times to reinforce the user's memory of such messages.
