When: Starts in the evening of September 27, and concludes after nightfall of September 29, 2021
What: The holiday of Sukkot is followed by an independent holiday called Shemini Atzeret. In Israel, this is a one-day holiday; in the Diaspora it is a two-day holiday, and the second day is known as Simchat Torah. This holiday is characterized by utterly unbridled joy, which reaches its climax on Simchat Torah, when we celebrate the conclusion—and restart—of the annual Torah-reading cycle.
How: These two days constitute a major holiday (yom tov), when most forms of work are prohibited. On the preceding nights, women and girls light candles, reciting the appropriate blessings, and we enjoy nightly and daily festive meals, accompanied by kiddush. We don’t go to work, drive, write, or switch on or off electric devices. We are permitted to cook and to carry outdoors (unless it is also Shabbat).
