Why the Date Isn’t Postponed in 2027
Tisha B’Av is never observed on Shabbat. When the 9th of Av lands on a Saturday, the fast moves to the 10th of Av. That is why the 2029 fast is pushed back a day.
In 2027, the 9th of Av falls on a Thursday, so the fast runs on its regular date with no shift.
What Is Tisha B’Av?
Tisha B’Av is a day of fasting and mourning for the destruction of the two ancient Temples in Jerusalem. It is often described as the saddest day on the Jewish calendar. The name simply means “the ninth of Av.” myjewishlearning
Both Temples fell on the same Hebrew date, about 655 years apart. Over the centuries, the day also became a time to remember other Jewish tragedies. hebcal
