Question: what is the day of the atonement?
Answer: Yom Kippur—the Day of Atonement—is considered the most important holiday in the Jewish faith. Falling in the month of Tishrei (September or October in the Gregorian calendar), it marks the culmination of the 10 Days of Awe, a period of introspection and repentance that follows Rosh Hashanah, the Jewish New Year.
