Palm Sunday occurs on the Sunday before Easter Sunday in the Western Christian liturgical calendar. It signals the upcoming end of Lent and the beginning of Holy Week. The day commemorates the spreading of palms and clothing in Jesus' path as He entered Jerusalem prior to His crucifixion:
They brought the donkey and the colt, placed their cloaks on them, and Jesus sat on them. A very large crowd spread their cloaks on the road, while others cut branches from the trees and spread them on the road. The crowds that went ahead of him and those that followed shouted, "Hosanna to the Son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!" (Matthew 21:7-9)
Many churches re-enact Jesus' return to Jerusalem with a processional in which participants wave palm branches. In areas where palm trees are unavailable, branches of the pussy willow, yew, and spruce trees are often used.
