yom kippur
Alysia Stanger The ritual, liturgy and meaning of Yom Kipper Yom Kippur is probably the most important holiday of the Jewish year. Yom Kippur, the Day of Atonement, comes on the tenth day of the Jewish month of Tisheri (September/ October). ... Actually, the Torah calls it Yom Kippurim. ... It is believed that those who have not been good enough to be written in the Book of Life immediately on Rosh HaShanah are given ten days to repent, pray for forgiveness, and do good deeds until Yom Kippur, when their fate will be decided. The Bible does not make any definitive connection between Yom Kippur and any historic event, but one tradition holds that it was on the tenth of Tishri that Moses came down from Mount Sinai to find Aaron and the Israelites dancing and reveling and worshipping the golden calf.
