Lag BaOmer, the 33rd day of the Omer count—this year, May 12, 2020—is a festive day on the Jewish calendar. It is celebrated with outings (on which children traditionally play with bows and arrows), bonfires, parades and other joyous events. Many visit the resting place (in Israel) of the great sage and mystic Rabbi Shimon bar Yochai, the anniversary of whose passing is on this day.
