Celebrated on the tenth day of Tishrei, it is the Jewish Day of Atonement; at the end of Yom Kippur, it is believed that one's fate is sealed. Jews are required to abstain from eating, drinking, washing, and sex, as well as indulgent dress such as jewelry, make-up, and leather. One traditionally wears white clothes to symbolize purity. In the afternoon, the Book of Jonah is read. A full day of prayers begins with the Kol Nidre, which releases Jews from vows or promises to God. As on Rosh HaShanah, the shofar is blown unless it is Shabbat, in which case the shofar is blown only during the final service, N'ila (meaning 'closing,' since the Temple gates were closed for this service).
