Tisha B'Av Date in the current year: August 13, 2024

Tisha B'Av Tisha B'Av (the Ninth of Av) is a day of mourning and fast day in Judaism. This day commemorates the destruction of the First and Second Temples in Jerusalem by the Babylonians and the Romans accordingly and subsequent exile of the Jewish people from the Holy Land.

Tisha B'Av also commemorates other calamities that befell the Jewish people on the same day. For example, in 135 CE, 500,000 Jews were massacred by the Romans at Betar fortress. In 1290, King Edward I exiled the Jews from England. In 1492, Jews were expelled from Spain on the 9th day of the month of Av.
