Rosh Hashanah is the Jewish New Year, it’s celebrated as the head of the Jewish year. It is the anniversary of the creation of Adam and Eve, and a day of judgment and coronation of God as king. The central observance of Rosh Hashanah is blowing the shofar (ram’s horn) on both mornings of the holiday, which is normally done in synagogue as part of the day’s services but may be done elsewhere for those who cannot attend.
