Palm Sunday is a Christian moveable feast that falls on the Sunday before Easter. The feast commemorates Jesus' triumphal entry into Jerusalem, an event mentioned in all four canonical Gospels. (Mark 11:1–11, Matthew 21:1–11, Luke 19:28–44, and John 12:12–19).

In many Christian churches, Palm Sunday is marked by the distribution of palm leaves (often tied into crosses) to the assembled worshipers. The difficulty of procuring palms for that day's ceremonies in unfavorable climates for palms led to the substitution of boughs of box, yew, willow, or other native trees. The Sunday was often designated by the names of these trees, as Yew Sunday, or by the general term Branch Sunday.

Lent (Latin: Quadragesima, "fortieth"^[1]) is an observance in the liturgical year of many Christian denominations, lasting for a period of approximately six weeks leading up to Easter. In most Western denominations Lent is taken to run from Ash Wednesday to Maundy Thursday (Holy Thursday) or to Easter Eve.

The traditional purpose of Lent is the preparation of the believer—through prayer, penance, repentance, almsgiving, and self-denial. Its institutional purpose is heightened in the annual commemoration of Holy Week, marking the death and resurrection of Jesus, which recalls the events of the Passion of Christ on Good Friday, which then culminates in the celebration on Easter Sunday of the resurrection of Jesus Christ.
