In the Christian calendar, Palm Sunday marks the beginning of Holy Week, which leads up to Easter Sunday.

Palm Sunday commemorates Jesus's triumphal entry into Jerusalem, seated on a donkey, shortly before the Last Supper and his crucifixion. The entry into Jerusalem is mentioned in all the New Testament gospels, where there is reference to people strewing garments and branches in Jesus's path. In the gospel of John (12:12-13), there is specific reference to palm trees:

much people ... took branches of palm trees, and went forth to meet him, and cried Hosanna ...

Palm Sunday is celebrated in different ways by Christian communities throughout the world; in some United Kingdom churches, crosses made out of palm leaves are provided for the congregation.
