what do you say at the end of yom kippur

The best greeting to give to someone observing Yom Kippur in English is "have an easy fast". It is not customary to greet those observing with "Happy Yom Kippur" as the day is not necessarily joyous and festive, but solemn and reflective. A more traditional greeting specific to Yom Kippur is "Gmar hatimah tovah" or "Gmar tov," which roughly translates to "a good seal". This greeting refers to the belief that the book of life, which determines an individuals fate for the coming year, opens on Rosh Hashanah and is sealed at the end of Yom Kippur following the period of repentance.
