Passover, or Pesach, is a major Jewish holiday commemorating the liberation of the Israelites from slavery in Egypt. It lasts for seven or eight days, marked by a ceremonial feast called the Seder. During Passover, Jews refrain from eating leavened bread (chametz) and instead eat matzah, unleavened bread, to symbolize the haste of their ancestors' departure from Egypt. The Seder includes symbolic foods and rituals retelling the Exodus story. Overall, Passover is a time for reflection, family gatherings, and celebration of freedom.
