Summary of AV
Av is the fifth of the twelve months of the Jewish calendar. The name Av literally means “father.” Av derives from the root, which means, “to will” or “to desire.”
This month is the “low point” of the Jewish calendar. The 9th of Av was the day the people of Israel chose to receive the negative report of the 10 spies and refused to enter the Promised Land. This date was also marked by the destruction of both the first and second Temples in Jerusalem.
