Yom Kippur is an important Jewish Holiday where Jews must fast for 25 hours starting from the evening before Yom Kippur at sunset and ending the evening of Yom Kippur after nightfall.
Yom Kippur is the most sacred and solemn day of the Jewish year.
On Yom Kippur, God makes the final decision on what the next year will be like for each person.
The Book of Life, opened at Rosh Hashanah, is closed and sealed, and those who have properly repented for their sins will be granted a happy New Year.
