- jewish calendar — the lunisolar calendar used by the Jews, in which time is reckoned from 3761 bc: regarded as the year of the Creation. The months, Nisan, Iyar, Sivan, Tammuz, Av, Elul, Tishri, Cheshvan, Kislev, Tevet, Shevat, and Adar, have either 29 or 30 days. Originally a new month was declared when the new moon was sighted in Jerusalem, but when this became impossible, a complex formula was devised to keep Rosh Chodesh near to the new moon. In addition, to keep the harvest festivals in the right seasons, there is a Metonic cycle of 14 years, in five of which an additional month is added after Shevat. The year according to biblical reckoning begins with Nisan, and the civil year begins with Tishri; the years are numbered from Tishri
