Feasts of the Church Year
The calendar of the church year includes two cycles of feasts and holy days. One cycle is based on the movable date of Easter Day, and the other is based on the fixed date of Christmas Day, Dec. 25. Easter Day is the first Sunday after the full moon that falls on or after Mar. 21. The four Sundays of Advent are the four Sundays before Christmas Day (BCP, p. 15). The principal feasts of the church year are Easter Day, Ascension Day, the Day of Pentecost, Trinity Sunday, All Saints' Day (Nov. 1), Christmas Day, and the Epiphany (Jan. 6). Ascension Day is celebrated on the Thursday forty days after Easter. The Day of Pentecost is the eighth Sunday after Easter, the fiftieth day of the Easter season. Trinity Sunday is the Sunday after the Day of Pentecost, nine Sundays after Easter. All Saints' Sunday is the Sunday following All Saints' Day, Nov. 1, and the feast may be observed on either day. The principal feasts take precedence over any other observance.
