This Christian observance falls on the Sunday before Easter and is the sixth and last Sunday of Lent, which began on Ash Wednesday. The beginning of Holy Week, Palm Sunday marks the day when Christ rode into Jerusalem a week before his death and resurrection and was greeted by its people, who strewed cloaks and tree branches along his path to honor him as their king. This event is known as the Triumphal Entry. Nowadays, Palm Sunday service often includes the blessing of palm leaves (or substitute branches from yews, willows, or other plants) before a procession into or in the church, after which hymns are sung and readings that focus on Christ’s final week are given. In many Christian denominations, palm fronds are burned at the end of the service; the ashes are saved for use on the next Ash Wednesday. Palm Sunday is also called Passion, Branch, Yew, Willow, Blossom, or Fig Sunday, as well as Flower Day and several other names.
