Lag B'omer
Lag B'omer, the 33rd day of the counting of the Omer, has always been associated with outings and joyus festivities. Lag B'omer celebrates the culmination of a tragic plague in Israel in Talmudic times, which has killed the students of Rabbi Akiva. It is also the Yahrzeit - anniversary of passing - of Rabbi Shimon Bar Yochai, the great Talmudic Sage and author of the Zohar.
Bais Menachem sponsors a yearly Lag B'omer picnic and outing for hundreds of children and adults. Often, three year old boys receive their first haircut on Lag B'omer.
