Still obscure outside of Israel, Tu B’Av is rapidly gaining popularity among American Jews. It’s a sort of Jewish Valentine’s Day — a holiday celebrating love, not long after Tisha B’Av, the day of mourning popularly known as the saddest day of the Hebrew calendar. It’s known as a great day of weddings, but you can “spread the love” any way you choose, including by celebrating with fellow members of your local Jewish community. Here are a few ways to do that in the Bay Area.

All events are free and take place on Friday, July 27 unless otherwise indicated.
