I got this from MyJewishLearning. It is a fabulous website with a lot of good resources for those who are wanting to learn about things considered Jewish or to get a Jewish perspective. This is basic information on Rosh Hashanah which this year falls on September 29th and 30th.
Rosh Hashanah, the Jewish new year, is a fall holiday, taking place at the beginning of the month of Tishrei, which is actually the seventh month of the Jewish year (counting from Nisan in the spring). It is both a time of rejoicing and of serious introspection, a time to celebrate the completion of another year while also taking stock of one’s life.
The High Holiday Period
The two days of Rosh Hashanah usher in the Ten Days of Repentance (Aseret Yemei Teshuvah), also known as the Days of Awe (Yamim Noraim), which culminate in the major fast day of Yom Kippur, the Day of Atonement. The Days of Awe represent the climax of a longer process. Starting at the beginning of the previous month, called Elul, the shofar is traditionally sounded at the conclusion of the morning service. A ram’s horn that makes a trumpet-like sound, the shofar is intended as a wake-up call to prepare for the Tishrei holidays. One week before Rosh Hashanah, special petitionary prayers called Selichot are added to the ritual. Rosh Hashanah itself is also known as Yom Hadin or the Day of Judgment, on which God opens the Books of Life and Death, which are then sealed on Yom Kippur.
The origins of Rosh Hashanah may be sought in a royal enthronement ritual of biblical times, though the Bible itself never mentions the “New Year” or “Day of Judgment” aspects of the holiday. Even though Rosh Hashanah falls in the seventh month, later rabbinic tradition decided to designate it the beginning of the year. Although the origin of this tradition may have been adopted from the Babylonians, the rabbis imbued it with Jewish significance as the anniversary of the day on which the world was created, or of the day on which humanity was created. Another explanation can be found in the significance of Tishrei as the seventh month, hence the Sabbath of the year.
The challah (traditional bread) that is eaten for the Rosh Hashanah season is round, symbolizing the eternal cycle of life. The challah is traditionally dipped in honey, symbolizing the hopes for a sweet New Year. The same is done with apples, which are made even sweeter with the addition of honey. Some people avoid eating nuts at this time, since according to a somewhat convoluted Gematria (mystical numerical interpretation) the Hebrew words for nut (egoz) and sin (het) have the same numerical value.
In the Community
Three unique sets of prayers are added to the morning service during Rosh Hashanah. These are known as Malkhuyot, which address the sovereignty of God, Zikhronot, which present God as the one who remembers past deeds, and Shofarot, in which we stand in nervous anticipation of the future.
Each of these sections culminates in the blasts of the Shofar, the most potent symbol of the holiday. The shofar is alluded to in the most memorable Torah reading for the holiday, the Akedah or Binding of Isaac (Genesis 22). The story and the shofar serve as reminders of the covenant between God and the people of Israel, carrying with them the message of sacrifice, hope, and continuity. Among the popular traditions associated with the holiday is a ceremony performed on the afternoon of the first day of Rosh Hashanah called tashlikh, when people throw crumbs or pieces of bread, symbolizing their sins, upon flowing water.
Theology and Themes
This is the time of year during which we are to atone for both our individual–and on Yom Kippur, our communal–sins committed over the course of the previous year, before God literally closes the books on us and inscribes our fates for the coming year. God’s rule over humanity and our need to serve God are stressed time and again over the course of the holiday
