April 22nd - April 30th
Passover begins at sundown and will last for eight days. Passover starts the eight-day celebration of the delivery of the Jews from slavery in Egypt. In Hebrew it is known as Pesach (which means "to pass over"), because God passed over the Jewish homes when killing the Egyptian firstborn on the very first Passover eve. Unleavened bread (matzoh) is eaten at this time.
