Pentecost (Πεντηκοστή [ἡμέρα]], 'the Fiftieth [day]') is a prominent feast in the Christian liturgical year commemorating the descent of the Holy Spirit upon the disciples of Christ after the Resurrection of Jesus.  The feast is also called Whit Sunday, Whitsun, or Whit, especially in the United Kingdom, where the following Monday was traditionally a holiday. Pentecost is celebrated seven weeks (50 days) after Easter Sunday, hence its name. Pentecost falls on the tenth day after Ascension Thursday.
