In synagogues, one section of the Torah is read on every Shabbat of the year. The last section, from Deuteronomy, is read on the holiday of Shemini Atzeret. Over the last 1000 years, the reading of the last section has become a big celebration called Simchat Torah, or "Rejoicing of the Torah". This celebration is so important that the whole day of the celebration is called "Simchat Torah." In Israel, this celebration happens on the single day of the holiday, 22 Tishrei. Outside of Israel, it happens on the second of the two days, 23 Tishrei.
