Sukkot is a Jewish holiday that celebrates the harvest season and commemorates the 40-year period during which the Israelites wandered in the wilderness, sleeping in tents. If you want to greet someone during Sukkot, there are several ways to do so. Here are some common greetings:

• Chag Sameach: This means "Happy Holiday" in Hebrew and applies to most Jewish holidays.
• Chag Sukkot Sameach: This means "Happy Sukkot".
• Moadim Lsimcha: This literally means "times of joy" but is used to wish someone a happy holiday. It is used on both Sukkot and Passover, particularly the intermediate days of the festival.
• Gut yom tov: This is the traditional Ashkenazi greeting, which means "Good day" in Hebrew and denotes a holiday.

If someone greets you with "Moadim Lsimcha," the traditional response is "chagim uzmanim lsasson," which means "holidays and times for celebration".
