Passion Week, also known as Holy Week, is the final week of Lent leading up to Easter. It commemorates the events of Jesus Christ's last days on Earth, including his triumphal entry into Jerusalem, the Last Supper, and his crucifixion. Each day of the week has specific significance, with Palm Sunday marking the beginning of the week. The week culminates in Good Friday, which remembers the crucifixion, and Easter Sunday, celebrating the resurrection of Jesus. Many Christian denominations observe this week with special services, prayers, and reflections on the themes of sacrifice, redemption, and hope.
