Yom Kippur, the "Day of Atonement", is the annual Jewish observance of fasting, prayer and repentance, considered to be the holiest day in 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.
