A communitywide Tisha B’Av commemoration program and service will be held 7 p.m. Monday, Aug. 8 at the shared home of Congregation Ner Tamid and Or Shalom Jewish Community in San Francisco.

The holiday, which commemorates the destruction of both the First Temple and Second Temple in Jerusalem, is traditionally a solemn day of fasting and remembrance.

The program will include a discussion about encouraging dialogue between the left and right in the Jewish community. It will bring together at least seven Bay Area congregations and groups for the first time. Confirmed are leaders or members of Congregations Emanu-El, Sherith Israel and Beth Israel Judea, along with the Coastside Torah Circle, the West Bay Havurah, Renewal havurot and Beit Yakov.

The event is jointly sponsored by Ner Tamid and Or Shalom and will be preceded by a dairy potluck dinner at 7 p.m., followed by traditional chanting of “Eikha” to candlelight. The program at 1250 Quintara St. is free and open to the public. For more information, visit www.nertamidsf.org or call (415) 242-9992 or (415) 661-3383.

The program is one of a handful of Tisha B’Av commemorations around the Bay Area. In the South Bay, Congregation Sinai will host a service on Monday, Aug. 8 at 1532 Willowbrae Ave., San Jose. For information, visit www.sinai-sj.org.
