What is Rosh Hashanah?
Rosh Hashanah is the birthday of the universe, the day G‑d created Adam and Eve, and it’s celebrated as the head of the Jewish year. It begins at sundown on the eve of Tishrei 1 (Sept. 6, 2021) and ends after nightfall on Tishrei 2 (Sept. 8, 2021).
The central observance of Rosh Hashanah is blowing the shofar (ram’s horn) on both mornings of the holiday (except on Shabbat), which is normally done in synagogue as part of the day’s services but may be done elsewhere for those who cannot attend.
I hope you have a celebratory holiday with family and friends enjoying food and good company.
