It is, after all, listed on most calendars you buy in the store, but remember: the holiday starts at sunset the night before the day shown on your calendar! This current Jewish year—5782 in the Hebrew calendar—is a sabbatical one, which began on the Jewish holiday of Rosh Hashanah in September 2021 and will end with the start of the same holiday in the fall of 2022.
Occurs in late January or early February.
