Holy week is the week between Palm Sunday and Easter. It is observed with special solemnity as a time of devotion to the Passion of Christ. Palm Sunday is the beginning of Holy Week - which commemorate Jesus’ triumphal entry into Jerusalem, where the crowds greeted him waving palm, branches, and crying out “Hosanna! Blessed is the one who comes in the name of the Lord! Blessed is the coming kingdom of our ancestors David! Hosanna in the highest heaven.”
