Jewish Passover, or PESACH in Hebrew, is an eight-day holiday that commemorates the Israelites' exodus from Egypt. It is celebrated by Jews around the world and is one of the most important holidays in the Jewish calendar. During the holiday, Jews abstain from eating leavened bread and instead eat matzah, a flat, unleavened bread. The holiday also includes special rituals such as the Seder, a festive meal that includes the retelling of the story of the Exodus.
