The liturgical year, also called the church year, Christian year, ecclesiastical calendar, or kalendar, consists of the cycle of liturgical days and seasons that determines when feast days, including celebrations of saints, are to be observed, and which portions of scripture are to be read.
Mass is the main Eucharistic liturgical service in many forms of Western Christianity. The term Mass is commonly used in the Catholic Church, Western Rite Orthodoxy, Old Catholicism, and Independent Catholicism. The term is also used in many Lutheran churches, as well as in some Anglican churches, and on rare occasion by other Protestant churches.
Advent is a season observed in most Christian denominations as a time of expectant waiting and preparation for both the celebration of the Nativity of Christ at Christmas and the return of Christ at the Second Coming. Advent is the beginning of the liturgical year in Western Christianity. The name was adopted from Latin adventus "coming; arrival", translating Greek parousia from the New Testament, originally referring to the Second Coming.
The Advent wreath, or Advent crown, is a Christian tradition that symbolizes the passage of the four weeks of Advent in the liturgical calendar of the Western church. It is traditionally a Lutheran practice, although it has spread to many other Christian denominations.
Kingdomtide or the Kingdom Season is a liturgical season observed in the autumn by some Anglican and Protestant denominations of Christianity. The season of Kingdomtide was initially promoted in America in the late 1930s, particularly when in 1937 the US Federal Council of Churches recommended that the entirety of the summer calendar between Pentecost and Advent be named Kingdomtide. In practice, most denominations that have adopted the Kingdom Season have restricted it to the later autumnal part of Ordinary Time.
Ordinary Time is the part of the liturgical year in the liturgy of the Roman Rite, which falls outside the two great seasons of Christmastide and Eastertide, or their respective preparatory seasons of Advent and Lent. Ordinary Time thus includes the days between Christmastide and Lent, and between Eastertide and Advent. The liturgical color assigned to Ordinary Time is green. The last Sunday of Ordinary Time is the Solemnity of Christ the King.
The Paschal Triduum or Easter Triduum, Holy Triduum, or the Three Days, is the period of three days that begins with the liturgy on the evening of Maundy Thursday, reaches its high point in the Easter Vigil, and closes with evening prayer on Easter Sunday. It is a moveable observance recalling the Passion, Crucifixion, Death, burial, and Resurrection of Jesus, as portrayed in the canonical Gospels.
The Feast of the Baptism of the Lord, or Theophany, is the feast day commemorating the baptism of Jesus in the Jordan River by John the Baptist. Originally the baptism of Christ was celebrated on Epiphany, which commemorates the coming of the Magi, the baptism of Christ, and the wedding at Cana. Over time in the West, however, the celebration of the baptism of the Lord came to be commemorated as a distinct feast from Epiphany. It is celebrated in the Catholic Church as well as the Anglican and Lutheran Churches on the first Sunday following The Epiphany of Our Lord. Some Lutheran churches celebrate it on the Sunday before Lent, or Quinquagesima.
The Solemnity of Our Lord Jesus Christ, King of the Universe, commonly referred to as the Feast of Christ the King, Christ the King Sunday or Reign of Christ Sunday, is a feast in the liturgical year which emphasises the true kingship of Christ. The feast is a relatively recent addition to the liturgical calendar, instituted in 1925 by Pope Pius XI for the Roman Rite of the Catholic Church. In 1970, its Roman Rite observance was moved from October to the last Sunday of Ordinary Time and thus to the end of the liturgical year. The earliest date on which the Feast of Christ the King can occur is 20 November and the latest is 26 November. It typically marks the end of Ordinary Time, which continues up until Advent Sunday, the first day of Advent. Depending on the year, Saint Andrew's Day, significant in some cultures, may fall prior to Advent Sunday. Thus, Christ the King is typically the last or second-to-last calendrical feast of the liturgical year.
Christian liturgy is a pattern for worship used by a Christian congregation or denomination on a regular basis. The term liturgy comes from Greek and means "public work". Within Christianity, liturgies descending from the same region, denomination, or culture are described as ritual families.
A lectionary is a book or listing that contains a collection of scripture readings appointed for Christian or Jewish worship on a given day or occasion. There are sub-types such as a "gospel lectionary" or evangeliary, and an epistolary with the readings from the New Testament Epistles.
Holy Monday or Great and Holy Monday is a day of the Holy Week, which is the week before Easter. According to the gospels, on this day Jesus Christ cursed the fig tree, cleansed the temple, and responded to the questioning of his authority.
Holy Tuesday or Great and Holy Tuesday, also known as Fig Tuesday, is a day of Holy Week, which precedes Easter. As with other days of Holy Week, this day is observed through the holding of church services.
The Feast of the Transfiguration is celebrated by various Christian communities in honor of the transfiguration of Jesus. The origins of the feast are less than certain and may have derived from the dedication of three basilicas on Mount Tabor. The feast was present in various forms by the 9th century, and in the Western Church was made a universal feast celebrated on 6 August by Pope Callixtus III to commemorate the raising of the siege of Belgrade (1456).
The Fifth Sunday of Easter is the fifth Sunday of the Easter season, being four weeks after the Christian celebration of Easter Sunday. In Western Christianity, this day is also known as the Fourth Sunday after Easter or Cantate Sunday. Eastern Christianity also calls this day the "Fifth Sunday," but typically using an Eastern synonym for Easter; for example, Fifth Sunday of Holy Pascha or Fifth Sunday of the Resurrection. In the Byzantine Rite, this day is also known as the Sunday of the Samaritan Woman.
A liturgical book, or service book, is a book published by the authority of a church body that contains the text and directions for the liturgy of its official religious services.
Pentecost season, also known Pentecostide, as well as the time of Sundays after Pentecost or Sundays after Trinity, is a liturgical period, celebrated by some Christian churches, which immediately follows the Easter season. Although the start and end dates vary by liturgical tradition, the season typically begins on the day of Pentecost and continues throughout the rest of the liturgical year, ending just before the season of Advent. The liturgical color for this period is typically green or red.
The Ordo Lectionum Missae, commonly referred to as OLM, is the main liturgical lectionary used in the Roman Catholic Church. It contains the designated Scripture readings for the celebration of the Mass of Paul VI, encompassing selections (pericopes) from both the Old and New Testaments of the Bible.
