Origin and usage
Seder is a Hebrew word meaning ‘order’ or ‘procedure’. It was first used in English in the mid 19th century.
The Jewish festival of Passover began on Wednesday and will continue until Thursday of next week. Like Easter, which falls this weekend, Passover or Pesach is a movable feast, occurring in March or April according to the lunar rather than the solar calendar. The festival commemorates the liberation of the Israelites from enslavement in Egypt. The first night of Passover is marked by a special meal called Seder whose different elements include retelling the story of the Exodus, drinking wine, and eating matzo as well as symbolic foods that recall these events.

“Passover and Easter are the only Jewish and Christian holidays that move in sync, like the ice skating pairs we saw during the winter Olympics.”
