The Jewish New Year. Rosh Hashana, starts at sundown. While most New Year celebrations celebrate the turning of a calendar, Rosh Hashana celebrates the creation of mankind:
Rosh Hashana, the Jewish New Year, commemorates the creation of mankind. God gave Adam a soul, distinguishing him from all other living beings, in his ability to make moral choices and to build a relationship with the Creator. On Rosh Hashana, each person's allotment of life and livelihood is subject to renewal. The Talmud says that on Rosh Hashana, the prayers of the barren women -- Sarah, Rachel and Chana -- were answered; on this day they became pregnant with Isaac, Joseph and the prophet Samuel, respectively. (Sarah's story is the Torah reading on the first day of Rosh Hashana, and Chana's story is the Haftarah.)
May the New Year bring you Health, Wealth and Happiness!
L'Shana Tova Tikatevu!
