The Babylonian Talmud, Taanit 29a, states that "when we enter [the month of] Av, our joy is diminished". This is because the darkest events in Jewish history occurred during the first week and a half of this month, particularly the Nine Days which culminate in Tisha B'Av, the 9th of Av. However, there is a minor and largely unknown holiday during the full moon of the month called Tu B'Av which was, in ancient times, one of the happiest days of the year. summer The month is also sometimes referred to as Menachem Av (Hebrew: מנחם אב‎) (Av of Comfort or Comforter of Father(s)), but most only use this title in the sanctification of the month recited on the Shabbat before Rosh Chodesh and following Tisha B'Av.[3]
