Shemini Atzeret (שמיני עצרת – “the Eighth [day] of Assembly”) is a Jewish holiday. It is celebrated on the 22nd day of the Hebrew month of Tishrei (first month of calendar). In the Diaspora, an additional day is celebrated, the second day being separately referred to as Simchat Torah. In Israel and Reform Judaism, the holidays of Shemini Atzeret and Simchat Torah are combined into a single day and the names are used interchangeably.
Shmini Atzeret begins at sundown on Sun, 20 October 2019.
