The holiday, like most Jewish holidays, begins at sundown on the evening before the first (full) day of the holiday. This begins the Jewish New Year and the Jewish month of Tishri. Rosh Hashanah signifies the beginning of the Days of Awe, a period of serious reflection about the past year and the year to come. This period, which continues until Yom Kippur, is a time for asking forgiveness from both God and people and for committing oneself to live a better life in the year to come. Traditionally, this is the time that God decides the fate of each Jew in the new year.
Recognizing the Festival/Holiday: There are many traditional foods eaten during the period between Rosh Hashanah and Yom Kippur. Eating apple dipped in honey or some other sweet dish is common. Honey cake is also popular. Either would make an appropriate and welcome gift. Common greetings include L'shana Tova, "Happy New Year," "Have a healthy and sweet New Year," and "May you be inscribed for a year of good health and happiness."
