Jewish Fast of Tisha B'Av 2026 Observed on July 22-23 with Traditional Restrictions and Mourning Practices

The fast of Tisha B'Av in 2026 begins at sunset on Wednesday, July 22, and ends at nightfall on Thursday, July 23, lasting approximately 25 hours. This solemn day commemorates the destruction of the First and Second Temples in Jerusalem and other historical tragedies affecting the Jewish people, marking the conclusion of the "Three Weeks" mourning period and the nine days of intensified mourning.

Tisha B'Av is one of the five major fasts in Jewish law and is considered as stringent as Yom Kippur, with five prohibitions observed from sunset to nightfall: no eating or drinking, bathing for pleasure, applying oils or lotions, wearing leather shoes, and sexual relations. Additional mourning customs include sitting on the floor or low stools until midday, reading the Book of Lamentations and kinnot (dirges), and refraining from wearing tefillin and tallit during morning prayers.

In 2026, since Tisha B'Av falls on a Thursday, preparations for Shabbat begin immediately after the fast ends. The fast times vary slightly by city, with entry times around 19:39-19:47 and exit times between 20:07-20:15, calculated by sunset and nightfall (stars out) respectively. No Havdalah ceremony is performed at the fast's conclusion this year, as it does not coincide with Saturday night.

The fast commemorates five key historical calamities, including the sin of the spies, the destruction of both Temples (586 BCE and 70 CE), the fall of Betar in 135 CE, and the Roman renaming of Jerusalem. Over time, other tragedies such as the 1492 Spanish expulsion and World War I's outbreak have been associated with this date. The day also serves as a moral reflection on societal divisions, inspired by rabbinic teachings that attribute the Temple's destruction to baseless hatred.

Practical guidance for the fast includes dietary preparation starting two days prior, gradual caffeine reduction, and a final pre-fast meal emphasizing complex carbohydrates and minimal salt or spices. Medical exemptions apply for pregnant women with complications, nursing mothers at risk, the ill, elderly, and children under bar/bat mitzvah age. Questions about daily activities such as bathing, tooth brushing, work, and smoking are addressed with specific halachic nuances.

Following the fast, some mourning customs continue until midday Friday, including abstaining from meat and wine, though leniencies exist for Shabbat preparations. The subsequent Shabbat is known as Shabbat Nachamu, symbolizing consolation after mourning. Community members are advised to consult local rabbinic authorities for specific customs and health concerns.
