For Jews around the world, this evening marks the beginning of the two day celebration of their New Year, Rosh Hashana.
The festival of Rosh Hashanah which means Head of the New Year is observed for two days beginning on the first day of the Jewish year. It is the anniversary of the creation of Adam and Eve, the first man and woman. The explanation below was excerpted from the web site Chabad.org
The central observance of Rosh Hashanah is the sounding of the shofar, the ram’s horn, which also represents the trumpet blast of a people’s coronation of their king. The cry of the shofar is also a call to repentance, for Rosh Hashanah is also the anniversary of man’s first sin and his repentance thereof, and serves as the first of the “Ten Days of Repentance” which culminate in Yom Kippur, the Day of Atonement. Another significance of the shofar is to recall the Binding of Isaac which also occurred on Rosh Hashanah, in which a ram took Isaac’s place as an offering to God; we evoke Abraham’s readiness to sacrifice his son, and plead that the merit of his deed should stand by us as we pray for a year of life, health and prosperity. Altogether, we listen to one hundred shofar blasts over the course of the Rosh Hashanah services.
Additional Rosh Hashanah observances include: a) Eating a piece of apple dipped in honey, to symbolize our desire for a sweet year, and other special foods symbolic of the new year’s blessings. b) Blessing one another with the words “Leshanah tovah tikateiv veteichateim,” “May you be inscribed and sealed for a good year.” c) Tashlich, a special prayer said near a body of water (an ocean, river, pond, etc.), in evocation of the verse, “And You shall cast their sins into the depths of the sea.” And as with every major Jewish holiday, after candlelighting and prayers we recite kiddush and make a blessing on the challah.
