The Jewish Holidays in august 2025

Tisha B'Av, Hebrew for the 9th day in the month of Av is, the anniversary of the destruction of the first and second temples in Jerusalem (586 BCE by the Babylonians, and 70 AD by the Romans, respectively).  This date is associated with other crimes against the Jews, such as the expulsion of the Jews from Spain in 1492.  In synagogues, the Book of Lamentations is read on Tisha b'Av.  This is a fast day that commences on the evening of August 2 and ends on the evening of August 3, 2025. Traditionally, there no weddings and no B'nai Mitzvah between the Fast of Tammuz (17 Tammuz/July 13, 2025) and Tisha b'Av.   

Tu b'Av is a minor holiday, referred to as the Holiday of Love (Chag ha'Ahavah, in Hebrew).  Six days after Tisha b'Av, one of the saddest days in the Jewish calendar, it is a joyous day.  Single women dance in the vineyards, all dressed in white, so that rich and poor look alike.  This is to attract the single men drawn to them and not their family's wealth.  Weddings frequently take place on Tu b'Av.  It may be counter-intuitive, but the other Holiday of Love in the Jewish calendar is Yom Kippur.  This is described in the Talmud, Seder Moed (Holidays), Tractate Taanit (Fast Days): 

• The mishna taught that Rabban Shimon ben Gamliel said: There were no days as happy for the Jewish people as the fifteenth of Av and as Yom Kippur. The Gemara asks: Granted, Yom Kippur is a day of joy because it has the elements of pardon and forgiveness, and moreover, it is the day on which the last pair of tablets were given.
