In Hebrew, Rosh Hashanah means, literally, “head of the year” or “first of the year.” It is celebrated as the Jewish New Year.
It is believed to be the anniversary of the creation of Adam and Eve, the first man and woman on this earth.
It is a two day celebration which begins on first day of the month of Tishrei, the first month of the Jewish calendar.
