What Is 33rd day of the Omer

Overview

The 33rd day of the Omer, known as Lag BaOmer, is a minor Jewish holiday that breaks the semi-mourning period observed during the counting of the Omer. This 49-day period begins on the second night of Passover and ends on Shavuot, symbolizing the spiritual journey from physical freedom to receiving the Torah.

Lag BaOmer is celebrated on the 18th of Iyar, which in 2025 falls on May 26. The name "Lag" is derived from the Hebrew letters Lamed (30) and Gimel (3), which together equal 33, hence "33rd day." This day is marked by joyous customs after 32 days of mourning practices.

• Counting the Omer lasts for 49 days, starting on the second night of Passover and ending the day before Shavuot, which commemorates the giving of the Torah.
• Lag BaOmer falls on the 33rd day, breaking a tradition of mourning linked to the death of 24,000 students of Rabbi Akiva during the 2nd century CE.
• The holiday is associated with Rabbi Shimon bar Yochai, a 2nd-century mystic who revealed deep Kabbalistic teachings on the day of his death in 160 CE.
• Customs include lighting bonfires, which symbolize the spiritual light of Rabbi Shimon’s teachings and are especially prominent in Meron, Israel.
• Many families schedule weddings and haircuts on this day, as these joyful activities are traditionally forbidden during the first 32 days of the Omer.

How It Works

Lag BaOmer functions as a spiritual pause in a period of restraint, allowing expressions of joy and celebration. The customs and timing are rooted in both historical events and mystical traditions within Judaism.

• Counting of the Omer: Each evening, Jews recite a blessing and count the day from Passover to Shavuot, a practice based on Leviticus 23:15–16. This ritual connects agricultural cycles with spiritual growth.
• Mourning customs: Many avoid weddings, haircuts, and listening to music from Passover until Lag BaOmer, in memory of Rabbi Akiva’s students who died in a plague during this period.
• Lag BaOmer celebrations: On this day, mourning restrictions are lifted, and people light bonfires, often at night, to honor Rabbi Shimon bar Yochai’s legacy of spiritual illumination.
• Bar Mitzvah celebrations: In Israel, it is customary to hold mass Bar Mitzvahs for 3-year-old boys at the tomb of Rabbi Shimon in Meron, where over 100,000 people gather annually.
• Kabbalistic significance: Rabbi Shimon is believed to have authored the Zohar, the foundational text of Kabbalah, and his death day is seen as a moment of divine revelation.
• Historical rebellion: Lag BaOmer also marks a pause in the Bar Kokhba revolt against Rome, with some traditions linking it to a temporary victory or respite during the conflict.
