Sukkot,[a] also known as the Feast of Tabernacles or Feast of Booths, is a Torah-commanded holiday celebrated for seven days, beginning on the 15th day of the month of Tishrei. It is one of the Three Pilgrimage Festivals on which Israelites were commanded to make a pilgrimage to the Temple in Jerusalem. Biblically an autumn harvest festival and a commemoration of the Exodus from Egypt, Sukkot’s modern observance is characterized by festive meals in a sukkah, a temporary wood-covered hut.
