Here’s What You Should Say to Someone Who Is Observing Yom Kippur

When Yom Kippur begins at sundown on Friday, Oct. 11, Jewish people around the world will begin to observe the holiest day of the year in their religion. For 25 hours—until nightfall on Saturday, Oct. 12—they will refrain from any food and drink, including water. They will spend the majority of the day in the synagogue, praying to God and repenting for their sins.

Unlike Rosh Hashanah, which comes just a few days before Yom Kippur, the day is not necessarily joyous and festive, but solemn and reflective. Consequently, it is generally not customary to greet those observing with “Happy Yom Kippur." The best greeting to give to someone observing Yom Kippur in English is “have an easy fast.” For those who are not fasting, but are observing the Yom Kippur, you can wish them a “Good Yuntif,” or “Yom Tov,” which are Yiddish and Hebrew, respectively, for “Have a good holy day.”

A more traditional greeting, and one specific to Yom Kippur, is “Gmar hatimah tovah,” or “Gmar tov,” which roughly translates to “a good seal.” Those observing the holiday believe that the Book of Life, which determines an individual’s fate for the coming year, opens on Rosh Hashanah, and is sealed at the end of Yom Kippur following the period of repentance.

Since Yom Kippur comes so close after Rosh Hashanah, you can say “Shana Tova,” or “Happy New Year.”
