Rosh Hashana, the Jewish New Year holiday, is held every year from 1 to 10 Tishri (falling in September or October) in the lunisolar Jewish liturgical calendar. It is a time of reflection upon one’s relationship as a Jew with God and upon God’s historical relationship with Israel, his chosen people. The holiday culminates in Yom Kippur, the “Day of Atonement,” which is an all-day period of fasting and prayer at the synagogue.
