Tisha b'Av (Hebrew: תִּשְׁעָה בְּאָב, romanized: Tišʿā bəʾĀḇ, lit. 'ninth of Av') is an annual ta'anit (fast day) in Rabbinic Judaism. (Qaraite Judaism fasts on the 7th and 10th of Av.) It is a commemoration of a number of disasters in Jewish history, primarily the destruction of both Solomon's Temple by the Neo-Babylonian Empire and the Second Temple by the Roman Empire in Jerusalem.
Tisha b'Av precedes the end of The Three Weeks. This day is regarded as the saddest day in the Jewish calendar. It is categorized as a day destined for tragedy. Tisha b'Av falls in July or August in the Gregorian calendar.
