Passover, also called Pesach, is a major Jewish holiday that occurs on the 15th day of the Hebrew month of Nisan, the first month of Aviv, or spring. The word Pesach or Passover can also refer to the Korban Pesach, the paschal lamb that was offered when the Temple in Jerusalem stood, to the Passover Seder, the ritual meal on Passover night, or to the Feast of Unleavened Bread. One of the biblically ordained Three Pilgrimage Festivals, Passover is traditionally celebrated in the Land of Israel for seven days and for eight days among many Jews in the Diaspora, based on the concept of yom tov sheni shel galuyot.
