“When Av enters, we must lessen our rejoicing,” declare the Talmudic sages in Ta’anit 26b.

In truth, however, this period of “sadness” begins on the Fast of the 17th of Tammuz ) and lasts exactly three weeks – until Tisha b’Av (the Ninth of Av), the day on which we mourn the destruction of both the First and Second Temples.

While all Jewish communities mark the 17th of Tammuz by mourning and fasting, in Ashkenazic communities, this mourning continues during the rest of the month of Tammuz by refraining from haircuts and shaving, listening to music, reciting a sheh’heh’cheh’yanu blessing on new garments, and celebrating weddings.

From the first day of the month of Av onward, however, almost all Jewish communities have accepted upon themselves the period of mourning referred to as “The Nine Days.” During these nine days, we customarily avoid the following activities (along with all of the above):

1) Eating meat or drinking wine (except on Shabbat).

2) Bathing or swimming for pleasure. Some people take quick showers using cool water instead of hot so as not to derive pleasure from the shower. (One may bathe on Friday in preparation for Shabbat.)

3) Doing laundry or wearing freshly laundered clothing (except for Shabbat). It is therefore customary to choose outfits for the nine days and wear them in advance of the nine days for just a few minutes so that they are not “fresh.” Children’s clothing may be laundered as needed.
