Sefirat HaOmer and Lag BaOmer Overview

  • What: The Omer is a count that lasts from the second night of Pesach until the holiday of Shavuot, for a total of 7 full weeks. Lag BaOmer is the 33rd day of Sefirat HaOmer, a date that is also the anniversary of the death of Rabbi Shimon Bar Yochai. The count is named for the Omer sacrifice, a wheat sacrifice that was brought during the times of the Temple.
  • When: On the Hebrew calendar, the Omer is counted from the 16th of Nisan until the 6th of Sivan. Lag BaOmer is celebrated on the 18th of Iyyar
  • How: The Omer is counted every night with a blessing. The count begins with day 1 and builds up to the 49th day. Both days and weeks are counted, leading up to the 7 weeks. It is customary to refrain from hosting celebrations such as weddings during the period of the Omer. The 33rd day of the count, Lag BaOmer, is celebrated by many people with bonfires, picnics, weddings, and live music (for many Ashkenazic Jews, this marks the start of the celebratory season, since the first half of the Omer count has now been completed). In Israel, many Jews make the pilgrimage to Meron in Northern Israel, to the burial site of Rabbi Shimon Bar Yochai.

  • When counting the 7 weeks of Sefirat HaOmer, we count up (day 1, day 2, etc.) instead of counting down (49 days left, 48 days left). Why do you think that is? What things in your life do you count down to and what do you count up?
  • Counting the 49 days of the Omer is a mitzvah that is dependent on remembering. If someone forgets to count for even one full day, many opinions say that the blessing for Sefirat HaOmer can no longer be recited, though one should continue to count each day without the blessing. Why do you think this is? Why is it so important to make sure not to miss even one day of the 49-day count?
  • The period of Sefirat HaOmer is considered by many to be a time of mourning. According to a Talmudic story, during this time period, thousands of the students of Rabbi Akiva died in a terrible plague. The reason given for this plague was the students’ inability to see past their differences and treat one another with respect and kindness. Why do you think that the way that Rabbi Akiva’s students treated one another mattered so much and caused such a big plague?
  • Rabbi Akiva was known for saying, “וְאָהַבְתָּ לְרֵעֲךָ כָּמוֹךָ: זֶה כְּלָל גָּדוֹל בַּתּוֹרָה – Love your fellow man as you love yourself: this is the most important principle in the Torah.” What are some ways that we can practice this in our everyday lives?
  • Some of the mourning practices that are customary for some groups of Jews during the period of Sefirat HaOmer include restrictions: no haircuts, no weddings, no live music, and more. Why is it important for us to still keep these restrictions and stay connected to something that happened at this time so long ago?
  • Lag BaOmer is celebrated, among other reasons, as the day that the plague stopped and the students of Rabbi Akiva were no longer dying. Because of this, many Ashkenazi Jews stop all mourning restrictions on this day, and Lag BaOmer is a day of celebration. How can we switch from a time of mourning to a time of celebration so quickly?
