"Three times shall you celebrate for me in the year"Exodus 23:14.

We are commanded to celebrate in the Holy Temple thrice yearly [during the festivals of Passover, Shavuot and Sukkot].

This festivity entails the offering of a Peace Offering, known as the Chagigah Offering.

Women are exempt from this mitzvah.

This is one of the three mitzvot associated with the festivals; the other two are Pilgrimage and Rejoicing.
