Passover is observed by the Jewish religion. It is a commemoration of the liberation of the Israelites from slavery in ancient Egypt, as described in the biblical book of Exodus. The holiday typically falls around late March or early April and is celebrated for 7 or 8 days, depending on the branch of Judaism. During the holiday, Jewish families gather for a Seder, a ritual feast that includes the retelling of the story of the Exodus and the eating of symbolic foods. Passover is one of the most significant holidays in the Jewish calendar and is observed by Jews around the world.
