The Catholic liturgical calendar is the cycle of seasons in the Roman Rite of the Catholic Church. The Church year begins each year with Advent, the season of awaiting Christ’s coming, and ends with the final Saturday of Ordinary time. Within the standard calendar year, the Church year starts in early December (or sometimes the end of November) and goes through the following November.

The Church year consists of six liturgical seasons: Advent, Christmas, Ordinary Time after Epiphany, Lent, Easter, and Ordinary Time after Pentecost. Seasons begin or end based on a movable feast and so some seasons vary in length from year to year, and vary as to the calendar dates.
