Av (also Menachem Av,[2] Hebrew: אָב, Modern: ʾAv, Tiberian: ʾĀḇ; from Akkadian ʾAbū "father") is the eleventh month of the civil year and the fifth month of the ecclesiastical year on the Hebrew calendar.[3] The name comes from Araḫ Abu, "month of Abu", from the Babylonian calendar. The name Ab (Arabic: آﺏ) also appears in the Arabic language for the month of August in the Levant (see Arabic names of calendar months).The name first appears in Second Temple literature, such as Megillat Taanit.[4] It is one of several months which are not explicitly named in the Hebrew Bible (Tanakh). It is a month of 30 days. Av usually occurs in July–August on the Gregorian calendar.

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.
