ABSTRACT:
An electronic calendar device capable of maintaining and displaying the date of the Hebrew, sometimes referred to as the Jewish, calendar which is based on the lunar cycle. In addition it is capable of computing the day of the week a certain Hebrew date will fall and corresponding Hebrew/Gregorian dates. The device corrects for all regular and irregular variations of the Hebrew calendar over a period of 10 years using a simple card or chip containing only prewired connections. Also displayed are the days of the week and the calendar year. The device requires a one pulse per day input which is available from standard electronic clock circuit chips in addition to the setting and computing input clock rates to be described.
