[[Liturgical Studies]] / Liturgical Calendar > [!note] New - 2026-03-26 ![[assets/covers/liturgical-calendar.jpg]] The Christian year organises the calendar around two major doctrines: the Incarnation of Christ and the Trinity. In doing so, the Prayer Book calendar reminds worshippers throughout the year of God’s redemptive work and the central truths of the faith. ## Theological Structure The church year divides into two halves.[^bray-common-prayer-p53] Half the year, beginning with Advent, celebrates the Incarnation through the feasts of Christmas and Epiphany; the other half is Trinity Season, running from Whitsunday through the remainder of the year.[^bray-common-prayer-p111] This organisation is not arbitrary. The two doctrines around which the calendar is built correspond to the deepest theological affirmations of Christian belief.[^bray-common-prayer-p53] Each feast and fast functions as a moment of remembrance, drawing the community back into key events of God’s redemptive work.[^bray-common-prayer-p110] ## Historical Roots [[Church History and Development|The practice of marking the Christian year according to doctrinal significance has ancient roots]]. Christians as early as the second century distinguished certain days based on events in the life of Christ.[^bray-common-prayer-p56] They observed Sunday as a feast day commemorating the [[Resurrection]], fasted on Friday to remember the Crucifixion, and in some traditions fasted on Wednesday to recall the Betrayal in Gethsemane.[^bray-common-prayer-p56] The dating of Christmas itself reflects centuries of theological reasoning. > [!quote] > ‘At first, in the Fast the birth of Christ was celebrated on January 6. But by the 400s the December 25 date became widely used throughout both the East and the West. It is unlikely that the December 25 date was taken from a pagan holiday.’ > > *How to Use the [[Book of Common Prayer]]: A Guide to the [[Anglican Liturgy]]*, p. 113 The selection of December was not arbitrary but rooted in theological logic: early Christians believed that great providential events recur on the same dates, and tradition held that Jesus died on 25 March.[^bray-common-prayer-p113] ## The Nativity Cycle The Incarnation half of the year begins with Advent and proceeds through Christmas, Epiphany, and the ‘Gesimas (pronounced ‘JEZ-i-muhs’) into Lent.[^bray-common-prayer-p111] Advent itself holds a double focus, remembering both the First Advent (Christ’s coming in the flesh) and the Second Advent (his return in glory).[^bray-common-prayer-p112] A single collect is said throughout the Advent season, binding the whole season together.[^bray-common-prayer-p112] Advent begins on the Sunday nearest to 30 November (Saint Andrew’s Day).[^bray-common-prayer-p112] The season leads through Christmas and the Twelve Days to Epiphany and its connected feasts. Three biblical stories are especially associated with Epiphany in the church’s tradition.[^bray-common-prayer-p115] The Nativity Cycle concludes with the Presentation of Christ in the Temple, which occurs forty days after Christmas Day on 2 February.[^bray-common-prayer-p115] This feast is also known as Candlemas, from an ancient custom of carrying lighted candles in procession, perhaps inspired by Simeon’s words in the Gospel: ‘For mine eyes have seen thy salvation, which thou hast prepared before the face of all people, a light to lighten the Gentiles, and the glory of thy people Israel.’[^bray-common-prayer-p116] ## Lenten Preparation and the Easter Cycle Before Lent proper comes the ‘Gesimas, a season of preparation that provides a transition into the great penitential season.[^bray-common-prayer-p117] Lent itself contains six Sundays, the last known as ‘The Sunday next before Easter’.[^bray-common-prayer-p122] Easter is followed by a season of celebration running through the Ascension and culminating in Whitsunday (Pentecost).[^bray-common-prayer-p111] The fifth Sunday after Easter is Rogation Sunday, which is followed by three days of fasting and prayer.[^bray-common-prayer-p127] Ascension Day is known in English tradition as ‘Holy Thursday’, a custom traceable to the time of King Alfred (reigned 871–899).[^bray-common-prayer-p128] Whitsunday, the celebration of the gift of the Holy Spirit, takes its name from an old practice of reserving this Sunday for baptisms, when those newly baptised wore white robes, making it ‘white, or whit, Sunday’.[^bray-common-prayer-p128] ## Trinity Season Trinity Sunday is a relatively late development in the Christian calendar, included in the Book of Common Prayer.[^bray-common-prayer-p130] The observance of Trinity Sunday spread during the 900s and became popular in England, France, Germany, and the Low Countries, though it did not become universal throughout the Western Church until the 1300s.[^bray-common-prayer-p131] ## Lectionary Integration The Prayer Book’s lectionary is integrated with the calendar. The Sunday first lessons for the Nativity Cycle begin in Advent with readings from the prophet Isaiah, which continue through Christmas and Epiphany.[^bray-common-prayer-p104] ## Selected passages > ![[assets/covers/bray-common-prayer.jpg|28]] ‘==At first, in the Fast the birth of Christ was celebrated on!
