In the Christian calendar, Whitsuntide (also known as Pentecost) is celebrated 50 days after Easter Sunday to commemorate the Holy Spirit descending on the disciples of Christ (Acts of the Apostles 2:1-31). It is said that in some parts of Britain, Whitsun celebrations have some of the characteristics of  those of Beltane, the Celtic festival held on May 1st to mark the beginning of Summer.

Two symbols of Whitsuntide are the dove and the columbine flower (genus: Aquilegia).
