The holiday started Saturday and will last eight days and eight nights, celebrating the liberation of the Israelites from slavery in Egypt. Passover starts with a traditional Seder [[ SAY-der ]] dinner, which includes the telling of the story of Moses leading the exodus out of Egypt. Those observing will eat matzo [[ MAH-tsah ]] instead of bread products during the holiday to commemorate the Israelites having to eat unleavened bread. Passover concludes at sundown on April 20th.
