Also called the Church Year or Liturgical Calendar. Starting with Advent and ending with Christ the King Sunday, the year is divided into seasons and punctuated with Festival Sundays.
The cycle of seasons of the church year, including, in order, Advent, Epiphany, Lent, Easter, and Pentecost (see specific definitions of each one).
the annual cycle of seasons and feasts that celebrates the Paschal Mystery (Christ's life, death, Resurrection and Ascension). The unfolding of the entire Christian story makes its power available once again in each retelling. The smallest unit of the liturgical year is the liturgical day, made holy through the Eucharist and the Liturgy of the Hours. Liturgical days are divided into four degrees of celebration: solemnities, feasts, obligatory memorials, and optional memorials. The source and center of the liturgical year is the Paschal Mystery, which the Church celebrates every day but most especially on the first day of the week known as the Lord's Day or Sunday, the first of all holy days.
The seasons and cycles of the Christian year. It is the instrument and means for leading God's people along the way to the Lord. The readings introduce and invite us into the Paschal Mystery. It includes: Christmas Cycle (the first Sunday of Advent through the Baptism of the Lord), Easter Cycle ( Ash Wednesday through Pentecost), and Ordinary Time.
The liturgical year, also known as the Christian year, consists of the cycle of liturgical seasons in some Christian churches which determines when Feasts, Memorials, Commemorations, and Solemnities are to be observed and which portions of Scripture are to be read. Distinct liturgical colours may appear in connection with different seasons of the liturgical year. The dates of the festivals vary somewhat between the Western (Roman Catholic, Anglican, and Protestant) churches and the Eastern Orthodox Churches, though the sequence and logic is the same.
