Rosh Hashanah 2013: Jewish people begin celebrating High Holy Days

Jewish people worldwide will begin the holiest time of their year at sundown Wednesday as Rosh Hashanah begins.

Rosh Hashanah, the date that marks the Jewish new year annually, begins at sundown Wednesday and continues through nightfall on Sept. 6.

The holiday marks the beginning of what are called the High Holy Days, a 10-day period that culminates with Yom Kippur on Sept. 13. On Yom Kippur - the day of atonement - the Jewish people are supposed to fast from sundown to sundown the next day.
