What Jewish Holiday Is In September 2024. Observances, study, faqs, videos, and music for all minor and major jewish holidays, festivals and fast days. All holidays begin at sundown.

Rosh hashanah, the jewish new year, and yom kippur, the day of atonement, form the high holidays, also known as the days of awe. The jewish year (5784, 5785, etc.) begins on rosh hashanah and ends just before the following rosh hashanah.
