A Seder (Hebrew: סדר, lit. 'order, arrangement') is a ritual feast that marks the beginning of the Jewish holiday of Passover. The Seder is conducted throughout the Jewish world on the evenings of the 15th day of Nisan in the Hebrew calendar, which falls in March or April in the Gregorian calendar. The Seder is based on the biblical story of the Exodus from Egypt, where the Israelites were freed from slavery. The Seder is described in the Haggadah, a Jewish text that sets forth the order of the Passover Seder. The Seder is conducted in the evening, beginning with a blessing over a cup of wine, and includes the partaking of symbolic foods, the recitation of blessings, and the singing of traditional Passover songs. The Seder is a time for families and friends to come together, to retell the story of the Exodus, and to celebrate the freedom that the Israelites gained. The Seder is also a time to reflect on the meaning of freedom and to consider how to apply the lessons of the Exodus to one's own life. In Yiddish, the Seder is known as a Seder Nacht, and in Ladino, it is called a Seder de Pésaj.
