A seder is a ceremonial dinner held during the Jewish holiday of Passover. It typically takes place on the first two nights of the holiday and involves reading from the Haggadah, a text that outlines the order of the meal and the story of the Exodus from Egypt. The meal includes symbolic foods, such as matzah (unleavened bread) and bitter herbs, which represent the hardships faced by the Jewish people. During the seder, participants engage in various rituals, including the four questions asked by the youngest child present. The evening is a time for family and community gatherings, emphasizing themes of freedom, remembrance, and gratitude.
