noun Jewish calendar n. A lunisolar calendar in use among Hebraic peoples, reckoning from the year 3761 b. c., the date traditionally given for the Creation. Note: It received its present fixed form from Hillel II. about 360 a. d. The present names of the months, which are Babylonian-Assyrian in origin, replaced older ones, Abib, Bul, etc., at the time of the Babylonian Exile. Nineteen years constitute a lunar cycle, of which the 3d, 6th, 8th, 11th, 14th, 17th, and 19th years are leap years. The year 5663 (1902-3 a. d.) was the first year of the 299th lunar cycle. The common year is said to be defective, regular, or perfect (or abundant) according as it has 353, 354, or 355 days. The leap year has an intercalary month, and a total of 383 (defective), 384 (regular), or 385 (perfect, or abundant) days. The calendar is complicated by various rules providing for the harmonious arrangement of festivals, etc., so that no simple perpetual calendar can be constructed.
