Sukkot is the Jewish harvest holiday. It starts in the Hebrew month of Tishrei, four days after Yom Kippur. In the western calendar it begins early fall and lasts for seven days. In 2015, Sukkot begins at sundown on September 27 ends October 4. It's also known as the Festival of Booths or Tabernacles. Based on a Biblical injunction, during Sukkot, Jews build outdoor huts called "sukkahs. They live, eat, pray and perform ceremonies using the "four species"--etrog (citron or lemon), lulav (palm fronds), willow twig (aravot) and myrtle twigs (hadassim).
