Christian Holy Week is the final week of Lent, leading up to Easter Sunday. It commemorates the events of Jesus Christ's last days on Earth, including his triumphal entry into Jerusalem, the Last Supper, and his crucifixion. The week begins with Palm Sunday, followed by Maundy Thursday, which remembers the Last Supper, and Good Friday, marking the crucifixion. The week culminates in Easter Sunday, celebrating the resurrection of Jesus, a central belief in Christianity. Holy Week is observed with various traditions and services in many Christian denominations.
