Tisha B'Av is observed on the ninth day of the Hebrew month of Av. In 2025, Tisha B'Av begins at sundown on August 2 and ends at nightfall on August 3. This date changes each year according to the Hebrew calendar, usually falling in July or August on the Gregorian calendar, and it commemorates the destruction of the First and Second Temples in Jerusalem, among other tragedies in Jewish history. If the ninth of Av falls on a Saturday (Shabbat), the fast is postponed to the tenth of Av. For upcoming years:
- 2026: July 22-23
- 2027: August 11-12
- 2028: July 31-August 1
Tisha B'Av is the saddest day on the Jewish calendar and is marked by a 25-hour fast and mourning practices.
