TISHABAV
Tisha B'Av
, is an annual fast day in Judaism which commemorates the destruction of the First and Second Temples in Jerusalem and the subsequent exile of the Jews from the Land of Israel. The day also commemorates other tragedies which occurred on the same day, including the Roman massacre of over 100,000 Jews at Betar in 132 CE. Instituted by the rabbis of 2nd-century Palestine, Tisha B'Av is regarded as the saddest day in the Jewish calendar and a day which is destined for tragedy.
