Pentecost

Pentecost (Ancient Greek: Πεντηκοστή, Pentēkostē , "the Fiftieth ") is a prominent feast in the calendar of ancient Israel celebrating the giving of the Law on Sinai, and also later in the Christian liturgical year commemorating the descent of the Holy Spirit upon the twelve Apostles of Christ. In the Eastern churches, Pentecost can also refer to the fifty days between Easter and Pentecost, hence the book containing the liturgical texts for Paschaltide is called the Pentecostarion. The feast is also called Whit Sunday, Whitsun, or Whit, especially in England, 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.
