Yom Kippur, the holiest day of the Jewish year, begins at sundown Friday.
Yom Kippur is the day of atonement. It marks the end of a 10-day period of reflection and repentance beginning after Rosh Hashanah, the Jewish new year.
Observant Jews will fast for 25 hours.
Yom Kippur ends at sundown Saturday with a blast from the shofar, an ancient instrument made of a ram’s horn.
