Ordinary Time
Ordinary Time refers to two periods of time in the Christian liturgical calendar, particularly the calendar of the ordinary form of the Roman Rite of the Catholic Church, although some other churches of Western Christianity also use the term. In Latin, the name of this time is Tempus per annum translated as time during the year.
Since 1970 in the ordinary form of the Roman Rite of the Catholic Church, Ordinary Time comprises two periods: one beginning on the day after the Feast of the Baptism of the Lord (the end of the Christmas season) and ending on the day before Ash Wednesday, the other beginning on the Monday after Pentecost, the conclusion of the Easter season, and continuing until the Saturday before the First Sunday of Advent. These periods of time combined are the longest time in the liturgical year.
The weeks of Ordinary Time are numbered. Several Sundays bear the name of feasts or solemnities celebrated on those days, including Trinity Sunday and the Feast of Christ the King.
