Tonight begins the Jewish festival, the seven days of Sukkot—celebrated by dwelling in the sukkah, taking the Four Kinds, and rejoicing, and followed by Simchat Torah.
What are the four kinds? A palm branch (lulav), two willows (aravot), a minimum of three myrtles (hadassim) and one citron (etrog). The first three kinds are neatly bundled together.
Sukkot—when we expose ourselves to the elements in greenery-covered huts—commemorates G‑d sheltering our ancestors as they traveled from Egypt to the Promised Land. The Four Kinds express our unity and our belief in G‑d’s omnipresence. Coming after the solemn High Holidays, it is a time of joy and happiness
The first two days (or one day in Israel) are yom tov, when work is forbidden, candles are lit in the evening, and festive meals are preceded with Kiddush and contain challah dipped in honey. The remainder of the days are quasi holidays, known as chol hamoed. We dwell in the sukkah and take the Four Kinds every day (except for Shabbat, when we do not take the Four Kinds).
