- Palm Sunday is the Christian moveable feast that falls on the Sunday before Easter. The feast commemorates Christ’s triumphal entry into Jerusalem, an event mentioned in each of the four canonical Gospels. Its name originates from the palm branches waved by the crowd to greet and honor Jesus Christ as he entered the city. Palm Sunday marks the first day of Holy Week; in Western Christianity, this is the beginning of the last week of the solemn season of Lent, preceding Eastertide, while in Eastern Christianity, Holy Week commences after the conclusion of Great Lent.
