Yom Kippur is the day when Jewish people atone for the sins we have committed over the past year. Jewish tradition believes that, on this day, G-d places a seal upon the "book of life," affecting each person for the coming year. This year, Yom Kippur begins at sunset on Tuesday, Sept. 22 and lasts through Wednesday, Sept. 23.
So, why do Jewish people fast on this holy day? Fasting is an opportunity for each of us to observe Yom Kippur in a most personal way. As we seek reconciliation with G-d and humanity, fasting touches the biological, as well as the spiritual, aspects of our being.
Why else do we fast? (from Our Jewish Learning)
So, what do you say when you see someone who is observing Yom Kippur, since "Happy Yom Kippur" doesn't seem appropriate. You can say, “Have an easy fast” or “May you be inscribed for a good year." It’s also acceptable to say “shana tova” (happy new year). With that, we hope everyone who celebrate has an easy fast, and that EVERYONE is inscribed for a good year!
In observance of Yom Kippur, the J will be closing at 3pm on Tuesday and will be closed all day Wednesday.
