Here are the dates of the most important Jewish holidays through 2030. These holidays move in the Western [Gregorian] calendar year since the Jewish calendar is a lunisolar calendar, instead of just a solar calendar. The dates are further complicated by how intercalary months are calculated and inserted. The length of different holidays varies between branches of Judaism, and they might differ for observers in or outside of Israel. Dates given for multi-day holidays are for the beginning of the holiday.
