ABSTRACT:
A calendar display apparatus comprising a calendar display panel device indicating the 1st to 31st days constituting at least one month which are arranged in a plurality of rows and columns in conformity to the serial order of the seven days of the week, wherein the calendar display panel device is supplied according to a referential clock pulse signal with at least "day" data and "month" data. A column data producing device is provided for specifying that column of the calendar on which there falls a particular day of the week in the month indicated by the "month" data. A column-specifying device receives column data delivered from the column data producing device for designating that column of the calendar in which there falls a particular day of the week. A "month"-shifting instruction generating device shifts month data forward or backward, and a data-shifting device varies the "month" data and also changes the column data supplied to the column-specifying device from the column data producing device.
