**Pentecost (also called Whit Sunday, Whitsunday or Whitsun) is a Christian holiday which takes place on the 50th day (the seventh Sunday) after Easter Sunday. It commemorates the descent of the Holy Spirit upon the Apostles and other followers of Jesus Christ while they were in Jerusalem celebrating the Feast of Weeks, as described in the Acts of the Apostles (Acts 2:1–31).
In Western Christianity, Pentecost is celebrated on the 50th day (the seventh Sunday) after Easter Sunday. In the United Kingdom, traditionally the next day, Whit Monday, was (until 1970) also a public holiday. (Since 1971, by statute, the last Monday in May has been a Bank Holiday). The Monday after Pentecost is a legal holiday in many European countries.
In Eastern Christianity, Pentecost can also refer to the entire fifty days of Easter through Pentecost inclusive; hence the book containing the liturgical texts is called the “Pentecostarion“. Since its date depends on the date of Easter, Pentecost is a “moveable feast“.
Pentecost is one of the Great feasts in the Eastern Orthodox Church, a Solemnity in the Roman Rite of the Catholic Church, a Festival in the Lutheran Churches, and a Principal Feast in the Anglican Communion. Many Christian denominations provide a special liturgy for this holy celebration.

You are all children of the light and children of the day. We do not belong to the night or to the darkness. So then, let us not be like others, who are asleep, but let us be awake and sober.
