Whitsunday, or Pentecost, is the seventh Sunday after Easter. For Christians, this commemorates the descent of the Holy Spirit in tongues of flame upon the apostles. Because the disciples were said to have begun baptizing thousands of people soon afterward, Whitsunday or Pentecost became the traditional time for baptisms. Whit, a corruption of white, refers to the white baptismal garments worn on this day. It is also a time of spring festivals throughout Europe, with echoes of pagan spring rites such as morris dancing and dressing a young boy in greenery (Jack-in-the-Green) and marching him through the village.
