Yom Kippur means "Day of Atonement" and refers to the annual Jewish observance of fasting, prayer and repentance. Part of the High Holidays, which also includes Rosh HaShanah, Yom Kippur is considered the holiest day on the Jewish calendar. In three separate passages in the Torah, the Jewish people are told, "the tenth day of the seventh month is the Day of Atonement. It shall be a sacred occasion for you: You shall practice self-denial."(Leviticus 23:27). Fasting is seen as fulfilling this biblical commandment. The Yom Kippur fast also enables us to put aside our physical desires to concentrate on our spiritual needs through prayer, repentance and self-improvement.
