The feast commemorates an event reported by all four Canonical Gospels (:Mark 11:1-11, Matthew 21:1-11, Luke 19:28-44, and John 12:12-19) - the Triumphal Entry of Jesus into Jerusalem in the days before his execution. Many Christians and Messianic Jews regard this event as the terminus of the first 69 weeks of Daniel's Prophecy of Seventy Weeks, and thereby a very holy day. Even setting this aside, the nature of the entry and its circumstances are usually deemed enough to warrant a special feast.
