ANNUAL CALENDAR

A calendar mechanism that adjusts automatically for the different lengths of the months March through January. It need be reset just once a year, at the end of February, because it doesn’t “know” whether February has 28 or 29 days in a given year. (Compare with “perpetual calendar”)
