Between Pesah and Shavuot, twenty-four thousand students of Rabbi Akiva died, and the weeks of the Omer became a time of mourning. Tradition teaches that the dying stopped on the thirty-third day.
The Kabbalists of Safed taught that Lag Ba'Omer is also the hilula of Rabbi Shimon bar Yohai, the day he passed away and revealed the secrets of the Zohar. A hilula is a wedding: the day a tzaddik's soul is joined to its source.
Sephardic communities, especially in North Africa, made it a night of light and song in honor of the tzaddik, alongside the great pilgrimage to his tomb in Meron.
Mourning and its end
During the Omer we do not hold weddings or cut hair, in memory of Rabbi Akiva's students.
Following Maran (Shulhan Arukh 493:2), Sephardim end the mourning on the morning of the 34th day; Ashkenazim, following the Rema, already on the 33rd. When the 33rd falls on Sunday, Sephardim may cut hair on Friday for Shabbat.
Tahanun is omitted on Lag Ba'Omer, and at Minha of the day before.
