Pentecost
Pentecost is a Christian holiday that commemorates the descent of the Holy Spirit upon the apostles and followers of Jesus Christ, as described in the New Testament of the Bible. It is celebrated 50 days after Easter Sunday, marking the end of the Easter season in the Christian liturgical calendar. Pentecost is often referred to as the birthday of the Christian Church, as it marks the moment when the apostles were empowered by the Holy Spirit to spread the message of Jesus to people of all nations. The holiday is observed with special church services, prayers, and traditions that vary among different Christian denominations.
