In 2021, Sukkot begins at sundown on Monday, Sept. 20 and ends at sundown on Monday, Sept. 27. The conclusion of Sukkot marks the beginning of the separate holidays of Shemini Atzeret and Simchat Torah. My Jewish Learning
It is traditional to build a sukkah, a temporary hut to dwell in during the holiday.
It is the custom to buy a lulav and etrog and shake them daily throughout the festival.
In the times of the Temple, Sukkot was also the time of a water-drawing ceremony, a wonderfully joyous and upbeat celebration.
