Holy week is the week leading up to Easter day. Starting with Palm Sunday when Jesus rode on a donkey and the people waved palm leaves and asked him to save them. Then there is "spy Wednesday",as a reference to the betrayal of Jesus by Judas Iscariot, followed by Maundy Thursday, Good Friday, Great Saturday and ending with Easter day.
Palm Sunday ~Is traditionally celebrated on the Sunday before Easter, in our church we pass out palm branches, some churches only give them to the children who walk in waving them in celebration of Jesus' triumphal entry into Jerusalem. Jesus rode a donkey into Jerusalem, and the celebrating people there lay down their cloaks in front of him, and also lay down small branches of trees.
