Liturgical year
The liturgical year (also known as the church year, Christian year, or ecclesiastical calendar) in the Roman Rite of the Catholic Church is the annual cycle of seasons, feasts, and days that structures the Church's public worship. It unfolds the entire mystery of Christ—from His incarnation, birth, life, passion, death, resurrection, ascension, and the sending of the Holy Spirit at Pentecost—to the expectation of His second coming. Through this cycle, the faithful participate in the Paschal Mystery and sanctify time itself.[1]
The liturgical year begins on the First Sunday of Advent (which may fall in late November or early December of the preceding calendar year) and concludes with the Solemnity of Christ the King in late November.
Canonical and theological basis
The structure of the liturgical year is governed by the Universal Norms on the Liturgical Year and the Calendar (promulgated in 1969 following the Second Vatican Council and the apostolic letter Mysterii Paschalis of Pope Paul VI).[2] These norms, incorporated into the liturgical books such as the Roman Missal, emphasize that "throughout the course of the year the Church unfolds the entire mystery of Christ... from the incarnation until the day of Pentecost and the expectation of blessed hope and of the coming of the Lord."[3]
The year combines two cycles:
- The Proper of Time (seasonal cycle) — focusing on the mysteries of Christ.
- The Proper of Saints (sanctoral cycle) — commemorating Mary and the saints.
The lectionary, revised after Vatican II, features a three-year cycle (Years A, B, C) for Sunday readings and a two-year cycle for weekdays.
Seasons
The Roman Rite liturgical year comprises six principal seasons (with some variations in length due to movable feasts):
| Season | Approximate Duration | Focus | Liturgical Color |
|---|---|---|---|
| Advent | Four Sundays before Christmas (late Nov/early Dec to 24 Dec) | Preparation for Christ's first coming (Nativity) and second coming (Parousia); watchful expectation | Violet (purple); rose on Gaudete Sunday (3rd Sunday) |
| Christmas (Christmastide) | From the Vigil of Christmas to the Feast of the Baptism of the Lord (usually mid-January) | Celebration of the Incarnation and manifestation of Christ (including Epiphany) | White |
| Ordinary Time (I) — after Christmastide | From the day after the Baptism of the Lord until Ash Wednesday | Christ's public ministry and teachings | Green |
| Lent | From Ash Wednesday to the evening of Holy Thursday | Penitential preparation for Easter; purification and conversion (recalling 40 days in the desert) | Violet (purple); rose on Laetare Sunday (4th Sunday) |
| Easter Triduum (Paschal Triduum) | From the evening of Holy Thursday to the evening of Easter Sunday | Summit of the liturgical year: Christ's passion, death, and resurrection | Red (Holy Thursday & Good Friday); white (Easter Vigil onward) |
| Easter (Eastertide) | From Easter Sunday to Pentecost Sunday (50 days) | Joyful celebration of the Resurrection and the descent of the Holy Spirit | White (or gold) |
| Ordinary Time (II) — after Pentecost | From the day after Pentecost until the Saturday before Advent | Growth in the Christian life; the Church's mission in the world | Green |
The Easter Triduum is considered the high point of the entire liturgical year.[4]
Comparison with other structures
| Feature | Roman Rite (Post-Vatican II) | Pre-1970 Roman Rite (Tridentine) | Eastern Catholic / Orthodox Traditions (example) |
|---|---|---|---|
| Starting Point | First Sunday of Advent | First Sunday of Advent | Varies (e.g., September 1 in some Byzantine calendars) |
| Number of Seasons | Six principal seasons | Included additional preparatory periods (e.g., Septuagesima, Passiontide) | Often nine seasons (e.g., Annunciation to Dedication in East Syriac) |
| Lectionary Cycle | Three-year Sunday / two-year weekday | One-year cycle | Varies by rite |
| Focus | Paschal Mystery as center; balanced sanctoral cycle | Greater emphasis on preparatory penitential periods | Stronger alternation of fasts and feasts; Paschal-centric |
