Rosh Hashanah is a two-day celebration, which begins on the first day of Tishrei. Tishrei is the first month of the Jewish civil year, but the seventh month of the ecclesiastical year.
The first day of the calendar year, Rosh HaShanah, on 1 Tishri is determined as follows: The new year starts on the day of the new moon that occurs about 354 days (or 384 days if the previous year was a leap year) after 1 Tishri of the previous year. If the new moon occurs after noon on that day, delay the new year by one day.
