The Season of Pentecost
The Long Green Season
Pentecost is the longest season of the church year. It stretches from the Feast of Pentecost (50 days after Easter), which marks the coming of the Holy Spirit, until Advent, the season of waiting and watching for the coming of Jesus. This season lasts about six months and may include as many as twenty-eight Sundays, depending on the date of Easter.
The Season of Pentecost is bounded by Trinity Sunday which is the First Sunday after Pentecost and Christ the King Sunday, the Last Sunday after Pentecost. This period may also be considered "ordinary time," a period of the church year not dedicated to a particular observance in the life of Christ. Ordinary time can be understood in terms of the living out of Christian faith and the meaning of Christ's resurrection in ordinary life. It may also be referred to as the "green season," because green is the usual liturgical color for this period of the church year.
