The Easter season, also known as the Great Fifty Days, begins at sunset Easter eve and continues through the Day of Pentecost.
It is the most joyous celebrative season of the Christian year. It focuses on Christ's resurrection, ascension and on the givings of the Holy Spirit on the first Easter (John 20: 22 - 23) and the Day of Pentecost (Acts 2). The ancient Christian name of the festival Pasch, derived from the Hebrew "pesah" (deliverance or passover), thus connecting the Resurrection to the Exodus. The origin of the English word Easter is disputed but may come from the Anglo-saxon spring goddess Eastre and her festival.
The liturgical colour for this season is white, symbolising purity and celebration.
