Rosh Hashana is the Jewish New Year festival, marking the Jewish
month of Tishri, also celebrated as the Birthday of the World. In fact, Judaism has four “new years” which mark various legal “years”, much like 1 January marks the “New Year” of the Gregorian calendar. Rosh Hashanah is the new year for people, animals, and legal contracts. The Mishnah also sets this day aside as the new year for calculating calendar years and sabbatical (”shemitta”) and jubilee (”yovel”) years. It lasts for two days. This holiday is the first of the ”Yamim Noraim” (“Days of Awe”), the most solemn days of the Jewish year.
