The Hebrew calendar or Jewish calendar is the calendar used by Jews for religious purposes. Nowadays it determines dates for Jewish holidays, the appropriate Torah portions for public reading, Yahrzeits (the date to commemorate the death of a relative), and the specific daily Psalms which some customarily read.
