Abstract
Abstract A calendar device includes first and second distinct cooperative sections. In the first section, calendar years are arranged in several groups and each group of years is designated by a character or marking to distinguish it from the other groups. In the second calendar section, an indicator for each day of each month is accompanied by indications of the names of the seven weekdays, and adjacent to the weekday indications are the characters or markings which identify years in the several groups of the first calendar section.
