Today is Lag BaOmer, the 33rd day of the Counting of the Omer. According to ReformJudaism.org, "[T]he period of the Omer is a time of semi-mourning, when weddings and other festivities are avoided, in commemoration of a plague that killed thousands of students of Rabbi Akiva, a Talmudic scholar. Lag BaOmer is considered to be the day on which the plague ceased, and thus became a day on which the mourning rituals are abandoned and replaced with great joy." Observed primarily in Israel, Lag BaOmer is celebrated with picnics and bonfires, as well as weddings.
