What to Say to Someone Who Is Observing Yom Kippur

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

Unlike Rosh Hashanah, which comes just ten days before Yom Kippur, the day is not necessarily joyous and festive, but solemn and reflective.
