Palm Sunday is a 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. Palm Sunday marks the first day of Holy Week. For adherents of mainstream Christianity, it is the last week of the Christian solemn season of Lent that precedes the arrival of Eastertide. In most liturgical churches, Palm Sunday is celebrated by the blessing and distribution of palm branches (or the branches of other native trees), representing the palm branches which the crowd scattered in front of Christ as he rode into Jerusalem; these palms are sometimes woven into crosses. The difficulty of procuring palms in unfavorable climates led to their substitution with branches of native trees, including box, olive, willow, and yew. The Sunday was often named after these substitute trees, as in Yew Sunday, or by the general term Branch Sunday. In Syriac Christianity it is often called Oshana Sunday or Hosanna Sunday based on the biblical words uttered by the crowd while Jesus entered Jerusalem. Many churches of mainstream Christian denominations, including the Orthodox, Catholic, Lutheran, Methodist, Anglican, Moravian and Reformed traditions, distribute palm branches to their congregations during their Palm Sunday liturgies. Christians take these palms, which are often blessed by clergy, to their homes where they hang them alongside Christian art (especially crosses and crucifixes) or keep them in their Bibles and daily devotional books. In the period preceding the next year's Lent, known as Shrovetide, churches often place a basket in their narthex to collect these palms, which are then ritually burned on Shrove Tuesday to make the ashes to be used on the following day, Ash Wednesday, which is the first day of Lent. Biblical basis and symbolism In the accounts of the four canonical Gospels, Christ's triumphal entry into Jerusalem takes place a week before his resurrection. Only the Gospel of John shows a timeline of the event, dated six days before the Passover. The raising of Lazarus is mentioned only by the Gospel of John, in the previous chapter. The Eastern Orthodox Church and the Eastern Catholic Churches which follows the Byzantine Rite, commemorate it on Lazarus Saturday, following the text of the Gospel. In fact, the Jewish calendar dates begin at sundown of the night beforehand, and conclude at nightfall. The Gospel of Matthew states that this happened that
