Tisha B’Av is an annual fast day in Judaism, named for the ninth day (Tisha) of the month of Av in the Hebrew calendar. The fast commemorates the destruction of both the First Temple and Second Temple in Jerusalem, which occurred about 656 years apart, but on the same Hebrew calendar date. Accordingly, the day has been called the “saddest day in Jewish history”.
