The Jewish New Year is called Rosh Hashanah. It is observed during the seventh month on the Hebrew calendar during the first two days of Tishrei, which is 10 days before Yom Kippur.
The High Holy Days in the Jewish tradition are kicked off by Rosh Hashanah, which is the only Jewish holiday that is celebrated for a full 2 days. People are not allowed to work during the holiday, and the tradition calls for extended time spent in the synagogue. A "casting off" traditional generally occurs on the first day, where Jews fill their pockets with small pieces of bread and find a river, stream, creek or other running water and empty their pockets into it.
