Abstract: An electronic calendar display in which each column always corresponds to a particular day of the week is disclosed. Each display element in each column includes a group of display segments which are selectively activated to display a number corresponding to a day of the month. Seven display elements are used to form a row representing a week, and six such rows may be arranged to represent an entire month. In addition, twelve month displays may be arranged to represent a year. The circuitry which updates the display segments includes a look-up table stored in a read-only memory which indicates the display segments to be activated for the current month and year. In the preferred embodiment, this circuitry also includes a microprocessor and the display includes alphanumeric display elements which can display a message. A keyboard or other interface permits an operator to enter the message. A watch is used to provide an indication of the current time and to signal when the display should be updated.
