Yom Kippur is often considered the holiest day in the Jewish calendar. Yom Kippur’s origins lie in a ritual purification of the Temple in Jerusalem from any accidental ritual impurities that had occurred in the past year. As repentance is the theme of Yom Kippur, the Jewish Day of Atonment is a day of self-denial with the goal of cleansing ourselves of sins. Prayer services are lengthy and solemn, and a 25-hour fast is kept. At the end of Yom Kippur, Jews traditionally share a joyful Break Fast meal with family and friends. The Yom Kippur breakfast is generally a festive breakfast menu consisting of foods such as eggs, cheese, bread. Note that in the Jewish calander, a holiday begins on the sunset of the previous day.
