The liturgical year is the way the Catholic Church organises time in order to relive, year after year, the whole mystery of Christ. It does not follow the civil calendar: it begins neither on January 1 nor on a fixed date, but on the First Sunday of Advent, and it unfolds like a great fresco stretching from the expectation of the Messiah to the gift of the Spirit, in the hope of the glorious return of the Lord.
This year is not a mere schedule of feasts. The Second Vatican Council states it forcefully: by distributing the mysteries of Redemption "throughout the course of the year", the Church makes present the saving works of her Lord, so that the faithful "may lay hold of them and be filled with saving grace"[1]. Time ceases to be an empty flight: it becomes the place where salvation is communicated.
Everything in this year revolves around a single centre: the Paschal Mystery, that is, the death and Resurrection of Christ. Sunday celebrates it every week; the Paschal Triduum celebrates it every year as "the high point of the entire liturgical year"[2]. Around this core unfold two intertwined cycles — the Temporal, which follows the seasons and feasts of the Lord, and the Sanctoral, which honours the Virgin Mary and the saints — and five great seasons: Advent, Christmas, Lent, the Triduum and Eastertide, and Ordinary Time.
This article gives an overview of this cycle: what the liturgical year is, why Christ is its content, how it took shape, how it is organised into seasons, ranks of celebration and colours, and what it means for Christian life. The detail of each season and each day is treated in the dedicated articles — on Sunday, Advent, Lent, the Paschal Triduum, Ordinary Time, the calendar of saints and holy days of obligation.
What is the liturgical year?
Before describing its workings, we must grasp the central idea. The liturgical year is not first of all a practical organisation of the ecclesiastical calendar: it is a way of believing in time. For Christianity, time is not a circle turning emptily, but a directed history in which God acts. The liturgical year is the concrete expression of this conviction.
A year that is not the civil calendar's
The first surprise is that the Christian year does not coincide with the civil year. It opens neither on January 1, nor at Easter, nor on a fixed date, but on the First Sunday of Advent — the Sunday nearest to November 30, a date that shifts between November 27 and December 3[3]. It closes nearly a year later, on the Saturday before the following Advent, after the solemnity of Christ the King of the Universe[4].
This choice is not arbitrary. By beginning her year with a season of waiting rather than with a feast, the Church says something about the Christian condition: before reliving the coming of Christ, she places herself back in the posture of the people who hope for Him. The year opens not on a triumph, but on a desire — the desire for Him who comes. This is the proper subject of Advent, the first threshold of the whole cycle.
Sanctifying time: making time a sign
The key word of all liturgical doctrine on the year is the sanctification of time. The Second Vatican Council places the liturgy "in time" as a prolongation of Christ's work: through feasts, the Church "devotes to the sacred memory of the saving acts of her divine Spouse" the days, weeks and seasons[5]. The natural rhythm — day and night, the week, the year — is not abolished but taken up and charged with new meaning.
"Holy Mother Church believes that it is for her to celebrate the saving work of her divine Spouse by devoutly recalling it on certain fixed days in the course of the year." — Second Vatican Council, constitution Sacrosanctum Concilium, § 102, December 4, 1963[6]
The Catechism takes up this idea down to the prayer of each day: the Liturgy of the Hours "sanctifies the different hours of the day with the praise of God", while the year as a whole sanctifies the course of the seasons[7]. Christianity therefore does not flee time: it transfigures it, making each Sunday an Easter and each year a journey through the mystery of Christ.
Memory, presence, expectation: the liturgical "today"
How can a feast "make present" an event twenty centuries old? This is where Christian liturgy differs from mere commemoration. To grasp what is at stake, take an image: a civil anniversary recalls a past fact that will not return; the liturgy claims to make the celebrated reality touched today.
The Catechism speaks of a liturgical "today": in celebrating the mysteries of Christ, the Church does not recite a memory, she enters a reality that is ever living, because the risen Christ "is the same yesterday, today and for ever" (Heb 13:8)[8]. The feast holds three times together: the memory of what Christ did, His effective presence through the sacraments, and the expectation of His return. This is what the eucharistic liturgy condenses in the acclamation: "We proclaim your death, we celebrate your resurrection, we await your coming in glory."
"The liturgical year, devotedly fostered and accompanied by the Church, is not a cold and lifeless representation of the events of the past, or a simple and bare record of a former age. It is rather Christ Himself who is ever living in His Church." — Pius XII, encyclical Mediator Dei, § 165, November 20, 1947[9]
This sentence of Pius XII is one of the keys to the whole subject: the liturgical year is not a museum of ancient feasts, it is Christ continuing His work in the time of the Church.
Liturgical year, cycle, calendar: clarifying the vocabulary
Three words recur and overlap, and it is useful to distinguish them. The liturgical year designates the unfolding of seasons and feasts over twelve months. The calendar is the concrete document that fixes, day by day, the celebration assigned to each date (the Calendarium Romanum generale for the universal Church, completed by proper calendars for dioceses and religious orders)[10]. The computus, finally, is the art of calculating the movable dates, beginning with that of Easter, on which Lent and Pentecost depend — a learned calculation treated separately in Why Does Easter Change Date?. The liturgical year thus combines fixed dates (Christmas on December 25) and movable dates (Easter and all that depends on it).
The centre of everything: the Paschal Mystery
The liturgical year cannot be understood as a series of juxtaposed feasts. It has a heart, and this heart commands all the rest: the Passover of Christ, that is, His passage from death to life. All other celebrations derive from it or lead to it.
Easter, the "Feast of feasts"
Easter is not one feast among others: it is the feast, the one of which the others are only the radiance. The Catechism says so in a formula that ranks the whole calendar.
"Easter is not simply one feast among others: it is the 'Feast of feasts,' the 'Solemnity of solemnities,' just as the Eucharist is the 'Sacrament of sacraments.'" — Catechism of the Catholic Church, § 1169[11]
From this central feast flows the very definition the Catechism gives of the year: it is not a collection of separate mysteries, but the unfolding of one alone.
"The liturgical year is the unfolding of the different aspects of the one Paschal mystery." — Catechism of the Catholic Church, § 1171[12]
That is why the window of Easter dates carries Lent, the Ascension and Pentecost along with it: to move the centre is to move the whole movable cycle. (Advent depends on Christmas, a fixed date: it does not move with Easter.)
The Paschal Triduum, summit of the year
If Easter is the centre, the Paschal Triduum is its liturgical summit: these three days — from the evening of Holy Thursday to the evening of Resurrection Sunday — celebrate the Supper, the Passion and the Resurrection as a single act of salvation. The Universal Norms use a luminous image: the Triduum shines forth as the culminating point of the whole year.
"Since Christ accomplished the work of human redemption and of the perfect glorification of God principally through His Paschal Mystery, the sacred Paschal Triduum of the Passion and Resurrection of the Lord shines forth as the high point of the entire liturgical year." — Universal Norms on the Liturgical Year and the Calendar, no. 18[13]
The same norm adds a correspondence of great clarity: "the pre-eminence that Sunday has in the week, the Solemnity of Easter has in the liturgical year"[14]. The detail of these three days — Holy Thursday, Good Friday, the Easter Vigil — is treated in The Paschal Triduum.
Why Christ is the content of the year
The liturgical year is Christocentric: its content is not a moral code, nor a series of religious seasons, but a Person. The Universal Norms state this from their opening: "throughout the course of the year the Church unfolds the entire mystery of Christ, from the Incarnation and the Nativity to the Ascension, to the day of Pentecost, and to the expectation of the blessed hope and of the coming of the Lord"[15]. Each season illuminates one facet of this unique mystery: Advent the expectation, Christmas the Incarnation, Lent conversion, Easter victory, Pentecost the gift of the Spirit. That is why the year, far from being a devout calendar, is a true catechesis in act: by journeying through it, the faithful receive, year after year, the totality of the faith.
Sunday, the first nucleus of the year
Even before a liturgical "year" existed, Christians had Sunday. It is the seed of all the rest: the original cell from which the annual cycle developed. The year therefore cannot be understood without starting from this day.
The Lord's Day, the "primordial feast day"
From the beginning, Christians gather "on the first day of the week" — the day of the Resurrection — for the breaking of the bread (Acts 20:7; 1 Cor 16:2). This day very early received the name of the Lord's Day (dies dominica, whence "Sunday" in the Romance languages)[16]. The Universal Norms give it an absolute rank.
"On the first day of each week, which is known as the Day of the Lord or the Lord's Day, the Church, by an apostolic tradition that draws its origin from the very day of the Resurrection of Christ, celebrates the Paschal Mystery. Hence, Sunday must be considered the primordial feast day." — Universal Norms on the Liturgical Year and the Calendar, no. 4[17]
The Second Vatican Council draws the consequence: Sunday is "the foundation and kernel of the whole liturgical year", the primordial feast day to be "proposed to the piety of the faithful and urgently impressed on them"[18]. No ordinary feast can therefore supplant it: the Sundays of Advent, Lent and Eastertide take precedence even over feasts of the Lord[19].
The week as a little year
Sunday makes the week a miniature of the year: every eighth day is a little Easter. It is by doubling and amplifying this weekly nucleus that the Church came to celebrate, once a year, the great annual Easter, then the whole cycle of mysteries around it. The relation between Sunday and the year is thus that of seed to tree: the year adds nothing to Sunday but its full unfolding. The meaning, history and obligations proper to the Lord's Day are developed in Sunday.
The two cycles: the Temporal and the Sanctoral
The liturgical year is read on two staves at once, like a score for two voices. The first follows Christ; the second follows those who followed Him. They are traditionally called the Proper of Time and the Proper of Saints.
The Proper of Time (de tempore)
The Temporal, or Proper of Time (proprium de tempore), groups the Sundays and liturgical seasons that celebrate the mysteries of the Lord: Advent, Christmas, Lent, the Triduum, Eastertide, Ordinary Time, and the great feasts of Christ (Epiphany, Ascension, Pentecost, Trinity, Corpus Christi, Christ the King). It is the backbone of the year: the chronological framework of the unfolded Paschal Mystery.
The Proper of Saints (de sanctis)
The Sanctoral, or Proper of Saints (proprium de sanctis), is the set of feasts fixed on a date of the civil calendar to honour the Virgin Mary and the saints, most often on the day of their death — their dies natalis, their "birth into heaven". The Council gives the reason: in celebrating the saints, the Church "proclaims the paschal mystery in the saints who have suffered and been glorified with Christ"[20]. The saints therefore do not compete with Christ: they are the Paschal Mystery verified in human lives. The detailed working of this calendar of saints — ranks, proper calendars, canonisations — is treated in The Calendar of Saints.
Precedence: time before saints
What happens when a saint's feast falls on an important day of the Temporal? The rule, laid down by the Second Vatican Council, is clear: the Proper of Time must keep "the precedence which is its due over the feasts of the saints", so that "the entire cycle of the mysteries of salvation may be fittingly observed"[21]. Concretely, a saint's memorial falling on a Sunday of Advent, Lent or Eastertide, or during the Triduum, gives way or is transferred. The table of precedence settles, rank by rank, these encounters of dates.
Mary in the liturgical year
The Virgin Mary holds a singular place, at the hinge of the two cycles. The Council explains that, in the annual cycle, the Church "honours with special love the Blessed Mary, Mother of God, who is joined by an inseparable bond to the saving work of her Son"[22]. Some of her feasts belong to the Temporal (the Mother of God on January 1, the Annunciation on March 25, nine months before Christmas), others to the Sanctoral (the Assumption on August 15, the Immaculate Conception on December 8)[23]. In her, says the Council, the Church "joyfully contemplates, as in a faultless image, that which she herself desires and hopes wholly to be"[24].
The liturgical seasons, one by one
The Temporal is composed of five great seasons, each illuminating one dimension of the mystery of Christ. Here is their sequence; the detail of each is referred to its own article, to avoid duplicating here what is developed elsewhere.
Advent: the season of coming
The year opens with Advent (from the Latin adventus, "coming"), four weeks of double expectation: the memory of Christ's first coming at Christmas, and the desire for His glorious return at the end of time[25]. Its colour is violet, softened by the rose of Gaudete Sunday. The meaning, history and liturgy of this season are developed in Why Does Advent Exist?.
Christmastide: the Incarnation made manifest
Christmastide opens on the night of December 24-25 and celebrates the manifestation of the Son of God made man: the Nativity, the Holy Family, Mary Mother of God, the Epiphany (the manifestation to the nations) and the Baptism of the Lord, which closes the season[26]. Its dominant colour is white, the colour of joy and light. The question of the December 25 date is itself the subject of its own article.
Lent: the ascent toward Easter
Lent opens, on Ash Wednesday, a penitential march of forty days toward Easter: fasting, prayer and almsgiving, after the image of Christ's forty days in the desert. Its colour is violet; the Alleluia and the Gloria are omitted. The meaning of the number forty and the counting of the days are explained in Why Does Lent Last Forty Days?.
The Triduum and Eastertide: "one great Sunday"
The Paschal Triduum (see The Paschal Triduum) opens Eastertide, fifty days of joy running from Easter to Pentecost. The Universal Norms give this period a striking definition.
"The fifty days from the Sunday of the Resurrection to Pentecost Sunday are celebrated in joy and exultation as one feast day, indeed as one 'great Sunday'." — Universal Norms on the Liturgical Year and the Calendar, no. 22[27]
It is the season of the recovered Alleluia, of the paschal candle, of the accounts of the Risen One's appearances; it culminates in the gift of the Holy Spirit at Pentecost, which closes the paschal cycle.
Ordinary Time: the mystery of Christ in its fullness
There remain the thirty-three or thirty-four weeks that belong to no strong season: this is Ordinary Time (per annum), divided into two blocks — between the Baptism of the Lord and Lent, then from Pentecost to Christ the King. Far from being "dead time", it has a precise object according to the Norms: in it "no particular aspect of the mystery of Christ is celebrated, but rather the mystery of Christ itself is honoured in its fullness, especially on Sundays"[28]. Its colour is green, the colour of hope and growth. This often misunderstood season is the subject of Ordinary Time.
The following table summarises the overall structure of the Temporal, with the approximate length and dominant colour of each season.
| Liturgical season | What it celebrates | Beginning | Approximate length | Colour |
|---|---|---|---|---|
| Advent | The expectation of Christ's twofold coming | 1st Sunday of Advent | 22 to 28 days | Violet (rose on the 3rd Sun.) |
| Christmastide | The Incarnation and manifestation of the Saviour | December 24 in the evening | 2 to 3 weeks | White |
| Ordinary Time (I) | The mystery of Christ in its fullness | After the Baptism of the Lord | 4 to 9 weeks | Green |
| Lent | Conversion, penitential ascent toward Easter | Ash Wednesday | 40 days (Sundays excluded) | Violet |
| Paschal Triduum | The Supper, the Passion and the Resurrection | Holy Thursday evening | 3 days | Red / white |
| Eastertide | The Resurrection and the gift of the Spirit | Easter Sunday | 50 days | White (red at Pentecost) |
| Ordinary Time (II) | The mystery of Christ in its fullness | After Pentecost | 23 to 28 weeks | Green |
The ranking of celebrations
Not all feasts carry the same weight. To order encounters of dates and give each mystery its relief, the Church classifies days by ranks. This hierarchy, simplified by the 1969 reform, structures the whole calendar.
Solemnities, feasts, memorials
Since the Universal Norms of 1969, celebrations are divided into three main ranks[29]. Solemnities are the highest days (Easter, Christmas, the Ascension, Pentecost, Epiphany, Trinity, Corpus Christi, the Immaculate Conception, the Assumption, All Saints, St Joseph, Sts Peter and Paul…): they begin on the previous evening, like Sunday, and include the Gloria and the Credo. Feasts (for example the Presentation of the Lord, the Transfiguration, the apostles, the evangelists) are celebrated within the limits of a day. Memorials, finally, obligatory or optional, simply commemorate a saint without interrupting the fabric of the season.
The table below presents these ranks, their scope and an example, so that the reader may see at a glance what each rank covers.
| Rank | What it marks | Liturgical scope | Examples |
|---|---|---|---|
| Solemnity | The greatest mysteries of salvation | Begins the previous evening; Gloria and Credo | Easter · Christmas · Pentecost · Assumption |
| Feast | A mystery or a major saint | Limited to the day; Gloria without Credo | Transfiguration · St John · Presentation |
| Obligatory memorial | A saint inscribed in the universal calendar | Proper collect and readings | St Augustine · St Teresa of Avila |
| Optional memorial | A saint who may or may not be celebrated | At the celebrant's choice | Many saints of the calendar |
| Ferial day | A day with no proper celebration | Follows the liturgical season | Ordinary weekdays |
Holy days of obligation
Among the solemnities, some are, for the faithful, holy days of obligation: days on which attendance at Mass and rest are prescribed as on Sunday. Their list, fixed by canon law and adapted country by country by the episcopal conferences, is the subject of Holy Days of Obligation and is not detailed here.
The liturgical colours
To each season and each feast corresponds a colour of vestments — the priest's garment, the altar hangings. Far from decorative, these colours are a language: they tell at a glance the meaning of the day. The present system, inherited from the Middle Ages and codified by the Roman Missal, retains four principal colours and two exceptional ones[30].
- White (or gold) expresses joy, light and glory: it clothes Christmas, Easter, feasts of the Lord that are not of martyrs, of the Virgin, of the angels and of non-martyr saints.
- Red, the colour of blood and fire, marks the feasts of the Passion (Good Friday, Palm Sunday), Pentecost and the Holy Spirit, the feasts of the Apostles and martyrs.
- Green, the colour of hope and growth, belongs to Ordinary Time.
- Violet signifies penance and expectation: it is the colour of Advent and Lent, and one of the possible colours for the dead.
- Rose, a softening of violet, is permitted twice a year: on Gaudete Sunday (3rd of Advent) and Laetare Sunday (4th of Lent), to announce the coming joy.
- Black may still be used for Masses for the dead and on November 2, although white or violet have often been preferred since the reform.
This grammar of colours is therefore no ornament: it is a visual catechism, teaching the faithful to read at a glance the season they are entering.
How the liturgical year took shape
The liturgical year did not fall ready-made: it is the fruit of a long growth of nearly twenty centuries, starting from a single day — Sunday — to reach the calendar we know. Tracing its great stages helps us understand why it has its present form.
From paschal Sunday to the annual cycle
In the beginning there is only Sunday, the weekly Easter. Then, from the 2nd century, an annual Easter appears, whose date provokes the famous "paschal controversy" between Asia Minor and Rome, settled in principle by the Council of Nicaea (325)[31]. Around this annual Easter first crystallise a time of preparation (the embryo of Lent) and a time of joy (the fifty days to Pentecost). The Christmas cycle, attested at Rome in the 4th century, forms independently, around December 25. It is the progressive addition of these nuclei that gives birth to the year.
- 1st-2nd centurySunday, the weekly Easter
Christians gather "on the first day of the week" for the breaking of the bread (Acts 20:7). Sunday is the original nucleus of the whole cycle.
- 2nd centuryThe appearance of an annual Easter
An annual celebration of Easter spreads. Its date provokes the "Quartodeciman controversy" between Asia and Rome.
- 325The Council of Nicaea fixes the principle of Easter's date
- 4th centuryThe Christmas cycle forms at Rome
The Nativity is celebrated on December 25; Epiphany, of Eastern origin, answers it. The two cycles — paschal and Christmas — coexist.
- 6th-11th centuryAdvent and the Roman structure
Advent, born of Gallic fasts, is integrated and reduced to four weeks. The sacramentaries fix the framework of the seasons.
- 1568-1570The Tridentine reform of St Pius V
After the Council of Trent, the Roman Breviary (1568) and Missal (1570) unify the calendar and prune a Sanctoral grown invasive.
- 1969The reform of Paul VI
The motu proprio Mysterii paschalis promulgates the Universal Norms and the new Roman calendar, recentred on the Paschal Mystery and Sunday.
The proliferation of the Sanctoral and the Tridentine reform
Over the centuries, the Sanctoral had developed so much that saints' feasts ended up covering most Sundays and ferial days, stifling the Temporal. The reform of St Pius V, after the Council of Trent — the Roman Breviary of 1568 and the Missal of 1570 — unified the calendar of the Latin Church and reduced this overabundant Sanctoral to restore the Proper of Time to visibility[32]. It was the first great ordering of the year on a universal scale.
From St Pius X to Pius XII: the return to Sunday
At the beginning of the 20th century, the concern to restore Sunday and the Temporal to their primacy returns with force. St Pius X reforms the Breviary and the place of Sundays (1911)[33], and the liturgical movement, born in the Benedictine abbeys, prepares minds for a thorough reform. Pius XII lays down its doctrinal principles in Mediator Dei (1947), where he defines the liturgical year not as a memory, but as Christ living in His Church[34]. The role of this current is developed in The Liturgical Movement.
Vatican II and the reform of Paul VI (1969)
The Second Vatican Council devotes chapter V of Sacrosanctum Concilium to the liturgical year (§ 102-111). It asks that the calendar be revised so that "the Proper of Time may be given the precedence which is its due over the feasts of the saints" and "the entire cycle of the mysteries of salvation may be fittingly observed"[35]. This revision results, on February 14, 1969, in Paul VI's motu proprio Mysterii paschalis, which promulgates the Universal Norms on the Liturgical Year and the Calendar and the General Roman Calendar: the framework still in force today[36]. The reform recentres the year on the Paschal Mystery and Sunday, simplifies the hierarchy of feasts and creates "Ordinary Time".
A year that is not a museum: the theology of the cycle
There remains the decisive question: why live by this calendar rather than by the civil calendar alone? The answer touches the heart of Christian faith about time and salvation.
Christ living in His Church
The deepest doctrine on the liturgical year holds in one sentence of Pius XII already quoted: this cycle "is not a cold and lifeless representation of the events of the past", but "Christ Himself who is ever living in His Church"[37]. In other words, in journeying through the year, the faithful do not merely learn the history of salvation: they are inserted into it. The mysteries of Christ, says Pius XII again, are "ever present and active", not in some vague way, but according to Catholic doctrine: sources of grace and models of Christian perfection[38]. The Second Vatican Council prolongs exactly this idea: in recalling the mysteries of Redemption, the Church "opens to the faithful the riches of her Lord's saving actions and merits, so that they may in some way be made present in every age"[39].
Dom Guéranger: "the manifestation of Jesus Christ"
The great herald of this spirituality, in the 19th century, is Dom Prosper Guéranger (1805-1875), restorer of the Benedictine order in France and author of a monumental Liturgical Year in fifteen volumes, which nourished generations of the faithful. He sums up the whole stake in one formula.
"The Ecclesiastical Year which we propose to develop in this work is nothing other than the manifestation of Jesus Christ and of His mysteries in the Church and in the faithful soul." — Dom Prosper Guéranger, The Liturgical Year, General Preface[40]
For Guéranger, to pray with the Church to the rhythm of her year is to enter into the purest prayer there is, for the public prayer of the Church is "the most pleasing to the ear and heart of God, and therefore the most powerful"[41]. The liturgical year is thus no external framework: it is a school of prayer and a pedagogy of salvation.
Living the liturgical year today
Concretely, to live the liturgical year is to let the Church's calendar give rhythm to one's own spiritual life: truly waiting in Advent, fasting in Lent, exulting for fifty days after Easter, honouring the Virgin and the saints on their feasts, sanctifying each Sunday as an Easter. It is also to pray the Liturgy of the Hours, which sanctifies the hours of the day as the year sanctifies the seasons (see The Liturgy of the Hours). The faithful who follow this cycle, year after year, receive the totality of the mystery of Christ — not as a lesson, but as a shared life. It is in this sense that the liturgy may be called, in the words of the Second Vatican Council, "the summit toward which the activity of the Church is directed, and at the same time the fount from which all her power flows"[42].

See Calendarium Romanum generale, 1969, and Catechism of the Catholic Church, § 1172, on the memory of the Virgin Mary "inseparably linked to the work of her Son".
23Universal Norms on the Liturgical Year and the Calendar, no. 39: Advent has a twofold character — preparation for Christmas, the memorial of the first coming, and directed toward the expectation of Christ's return at the end of time. The detail (length, "O" antiphons, colour) is treated in the article devoted to Advent.
25Christmastide runs from the night of the Nativity (December 24-25) to the Sunday of the Baptism of the Lord inclusive. It includes the solemnity of the Nativity, the feast of the Holy Family, the solemnity of Mary Mother of God (January 1), the solemnity of the Epiphany and the feast of the Baptism of the Lord. See Universal Norms on the Liturgical Year and the Calendar, no. 32-38.
26Universal Norms on the Liturgical Year and the Calendar, no. 22. Original: "The fifty days from the Sunday of the Resurrection to Pentecost Sunday are celebrated in joy and exultation as one feast day, indeed as one 'great Sunday'. These are the days above all others in which the Alleluia is sung."
27Universal Norms on the Liturgical Year and the Calendar, no. 43. Original: "there remain in the yearly cycle thirty-three or thirty-four weeks in which no particular aspect of the mystery of Christ is celebrated, but rather the mystery of Christ itself is honoured in its fullness, especially on Sundays. This period is known as Ordinary Time." No. 44 specifies the bounds of Ordinary Time (from the Monday after the Baptism of the Lord to Shrove Tuesday, then from the Monday after Pentecost to the Saturday before Advent).
28Universal Norms on the Liturgical Year and the Calendar, no. 10-15, which distinguish solemnities, feasts and memorials (obligatory or optional), and regulate their celebration. The table of liturgical days and their precedence appears as an appendix to the Norms.
29On liturgical colours, see the General Instruction of the Roman Missal (Institutio generalis Missalis Romani), no. 345-347, which fixes the use of white, red, green and violet, as well as the exceptional use of rose (Gaudete and Laetare Sundays) and black (Masses for the dead).
30The Council of Nicaea (325) laid down the principle of a common date for Easter — a Sunday, after the spring equinox, independently of the Jewish calendar — without itself fixing the formula of calculation, which was worked out afterwards, notably at Alexandria. The detail of this history and of the paschal computus is treated in the article on Easter's date.
31After the Council of Trent (1545-1563), St Pius V promulgated the Breviarium Romanum (1568) and the Missale Romanum (1570), which unified the liturgy of the Latin Church and reduced an overabundant Sanctoral in order to restore the Proper of Time to its rightful place. See "Ecclesiastical Year", The Catholic Encyclopedia, vol. 5, Robert Appleton Company, New York, 1909.
32St Pius X, apostolic constitution Divino afflatu (November 1, 1911) and reform of the Roman Breviary: he redistributes the psalter over the week and restores to Sundays and ferial days their liturgical precedence, beginning the return to the primacy of the Temporal that would culminate in the 1969 reform. See the article on the liturgical movement.
33Dom Prosper Guéranger (1805-1875), The Liturgical Year, General Preface (first volume, Advent, 1841). Abbey of Solesmes / Société Saint-Jean-l'Évangéliste, Desclée. Guéranger, restorer of the Benedictine abbey of Solesmes, is one of the great figures of the 19th-century liturgical renewal.
40Dom Prosper Guéranger, The Liturgical Year, General Preface: "The prayer of the Church is therefore the most pleasing to the ear and heart of God, and therefore the most powerful." (English translation of the French text).
41Second Vatican Council, Sacrosanctum Concilium, § 10: the liturgy is "the summit toward which the activity of the Church is directed, and at the same time the fount from which all her power flows". This principle applies eminently to the liturgical year, the unfolding in time of the Church's liturgical action.
