How to Holiday: Tisha b’Av + Tu b’Av Essentials: The month of Av brings us a pair of holidays: Tisha b’Av, the saddest day in our calendar, and Tu b’Av, a celebration of love. How do we observe this strange pairing? Join Rabbi Steven to learn about the essential elements of these holidays so that you can make them your own. All learners are welcome! If you are a Jew-by-Choice or in the process of conversion, join us for a special part two before Mishkan’s Tisha b’Av observances on Monday, August 12.
