Most people have heard of Hanukkah and Passover and maybe Yom Kippur — the Jewish Day of Atonement. But Tisha B’Av?

Translated as the ninth day of the Hebrew month of Av, it counts as one of the most important days on the Jewish calendar. But even many Jews have not heard of this period of mourning, which requires a 25-hour fast to commemorate the destruction of the First and Second Temples in Jerusalem.

Tisha B’Av, many rabbis say, can be a tough sell, in part because a radical group of far-right Jews wants to rebuild the temple on the site of what is now the Al-Aqsa Mosque, one of Islam’s most revered sites.
