From sundown on Saturday, May 24 to nightfall on Sunday, May 25, 2092. 18 Iyyar 5852 · ל״ג בעומר Lag BaOmer (Hebrew: לַ״ג בָּעוֹמֶר, LaG Bāʿōmer lit. '"33rd [day] in the Omer"'), also Lag B'Omer or Lag LaOmer, is a Jewish religious holiday celebrated on the 33rd day of the Counting of the Omer, which occurs on the 18th day of the Hebrew month of Iyar. According to the Rishonim, the plague that killed 24,000 of Rabbi Akiva's students ended on Lag BaOmer. For some communities, the mourning period of the Counting of the Omer thus concludes on Lag BaOmer. The Hillula of Rabbi Shimon bar Yochai, is held on Lag BaOmer to mark the anniversary of his death. According to a late medieval tradition, pilgrimages are made to the burial place of Shimon bar Yochai in Meron on this day. The holiday also serves to commemorate the Bar Kokhba revolt against the Roman Empire. Wiki link Dates: Hebcal.com (CC BY 4.0), Diaspora schedule. Text: Wikipedia (CC BY-SA).
