Pesach

In Judaism, an eight-day spring festival that commemorates the Exodus of the Israelite slaves from Egypt and the ten plagues sent to Egypt by God. In particular, it remembers the passing over, by the Angel of Death, of the Jewish houses, so that only the Egyptian firstborn sons were killed in retribution for the pharaoh's murder of all Jewish male infants.

Like other Jewish festivals, Pesach follows a lunar calendar. It often coincides with Easter, the only Christian festival to be set by the lunar calendar, because the Last Supper, celebrated by Jesus with his disciples, was a Pesach Seder (ceremonial meal).
