Lag Ba'Omer is a Jewish holiday observed worldwide on the 33rd day of the Counting of the Omer, which falls on May 5. This holiday commemorates the death anniversary of Rabbi Simeon bar Yochai and is also associated with the Bar Kokhba revolt against the Roman Empire and Rabbi Akiva. Notable customs include lighting bonfires and engaging in bow-and-arrow play, symbolizing Simon Bar Kokhba's military victories. Families often celebrate by going on outings and picnics, and it is common for Ashkenazi Jews to schedule weddings on this day, as the mourning restrictions of the Omer period are lifted.
