HebrewCalendar

Synopsis

This calendar class implements the Hebrew calendar. This complicated calendar determines leap years within a 19-year cycle. The 3rd, 6th, 8th, 11th, 14th, 17th, and 19th years are leap years. Regular years have 12 months and between 353 to 355 days, leap years have 13 months and between 383 to 385 days; the variance is determined by the placement of Jewish holidays. This implementation recognizes the years 5343 to 6000 (A.M.), which is equivalent to the Gregorian years 1582 to 2240.
