What comes before Pentecost?

Before Pentecost, Christians observe the period of Easter, which celebrates the resurrection of Jesus. Pentecost occurs fifty days after Easter Sunday and commemorates the descent of the Holy Spirit upon the apostles. This event is significant as it marks the birth of the Christian Church and the beginning of its mission to spread the Gospel. Additionally, the week leading up to Pentecost is often referred to as the Easter season or the Great Fifty Days.
