22nd day of Tishrei
Shemini Atzeret is a one-day festival, which marks the conclusion of Sukkot. The rituals of kiddush and candle lighting are upheld, and ritual prayer for rain is recited. According to tradition, the world is judged at this time for how much rain will fall during the year. The yizkor, or memorial prayer for the dead, is also recited during Shemini Atzeret, as it marks the conclusion of Sukkot.
