Sukkot or Succoth is a 7-day festival, also known as the Feast of Booths, the Feast of Tabernacles, or just Tabernacles. It is one of the three pilgrimage festivals mentioned in the Bible. The word sukkot is the plural of the Hebrew word sukkah, meaning booth. Jews are commanded to "dwell" in booths during the holiday. This generally means taking meals, but some sleep in the sukkah as well. There are specific rules for constructing a sukkah. The seventh day of the holiday is called Hoshanah Rabbah.
