3 Tammuz –
Gimmel Tammuz – is a
Chabad holiday that marks the anniversary of the passing of Rabbi
Menachem Mendel Schneerson, the seventh Rebbe of the Chabad-Lubavitch Hasidic dynasty.
17 Tammuz –
Seventeenth of Tammuz – is a fast day from 1 hour before sunrise to sundown in remembrance of Jerusalem's walls being breached. 17 Tammuz is the beginning of
The Three Weeks, in which Jews follow similar customs as the ones followed during the
Omer from the day following
Passover until the culmination of the mourning for the death of the students of
Rabbi Akiva (the 33rd day of the Omersuch as refraining from marriage and haircuts.) The Three Weeks culminate with
Tisha B'Av (9th of Av). :Ashkenazi communities refrain from wine and meat from the beginning of the month of
Av, while Sefardi communities only do so from the second day of the month. The mourning continues until noon on the 10th of Av, the date on which the Second Temple's destruction was complete. == In Jewish history ==
