Ordinary Time (Latin: Tempus per annum) 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 word "ordinary" as used here comes from the ordinal numerals by which the weeks are identified or counted, from the 1st week of Ordinary Time in January to the 34th week that begins toward the end of November.[better source needed]
In the ordinary form of the Roman Rite, the Feast of the Baptism of the Lord, which ordinarily occurs on the Sunday after the Solemnity of the Epiphany of the Lord (6 January), begins Ordinary Time and closes the Season of Christmas. The weekdays that follow the Feast of the Baptism of the Lord are reckoned as belonging to the first week of Ordinary Time which continues until the Tuesday that immediately precedes Ash Wednesday.
After Eastertide the Ordinary Time resumes on the Monday after the Solemnity of Pentecost. In regional calendars where Whitmonday is a Day of Obligation, Ordinary Time and the use of the liturgical colour Green may begin on the following Tuesday.
The decision to treat the whole of Ordinary Time as a unit led to abandonment of the previous terminology, whereby the Sundays of the first period were called Sundays after Epiphany and those of the second period Sundays after Pentecost.
The last Saturday is nominally the XXXIV Saturday, as the second part of the Ordinary Time is counted backwards from the 34th week.
Depending on where the XXXIV Saturday falls from 26 November to 2 December, the Ordinary Time will have 33 or 34 weeks.
If the XXXIV Saturday falls on 26/27/28/29 November, the Ordinary Time will have 33 weeks.
If the XXXIV Saturday falls on 30 November or 1/2 December, the Ordinary Time will have 34 weeks.
Ordinary Time with 33 weeks.
Ordinary Time with 34 weeks.
An other, easier way to say the "33 or 34 rule" follows.
If the following liturgical year starts in November, the previous liturgical year's Ordinary Time will have 33 weeks.
If the following liturgical year starts in December, the previous liturgical year's Ordinary Time will have 34 weeks.
The celebration of an Ordinary Time weekday gives way to that of any solemnity, feast, or obligatory memorial that falls on the same day, and may optionally be replaced by that of a non-obligatory memorial or of any saint mentioned in the Roman Martyrology for that day.
The solemnities, feasts, and commemorations of the General Roman Calendar which may, according to the Ranking of liturgical days in the Roman Rite, replace a Sunday of the Ordinary time are:
The Universal Norms on the Liturgical Year and the General Roman Calendar also lists as proper solemnities (which outrank in the relevant church building or community Sundays in Ordinary Time):
Following the lead of the liturgical reforms of the Roman Rite, many Protestant churches also adopted the concept of an Ordinary Time alongside the Revised Common Lectionary, which applies the term to the period between Pentecost and Advent. However, use of the term is not common.
Those that have adopted the Revised Common Lectionary include churches of the Anglican, Methodist, Lutheran, Old Catholic and Reformed traditions.
Some Protestant denominations set off a time at the end of Ordinary Time known as Kingdomtide or Season of End Times. This period can range anywhere from only the three Sundays prior to Christ the King (as in the Wisconsin Synod Lutheran) to 13 or 14 weeks (most notably in the United Methodist Church). The Church of England observes this time between All Saints and Advent Sunday.
In some traditions, what in the Roman Rite is the first period of Ordinary Time is called Epiphanytide (beginning on Epiphany Day in the Anglican Communion and Methodist churches) and from Trinity Sunday to Advent is called Trinitytide. In the Church of England, Sundays during "Ordinary Time" in this narrower sense are called "Sundays after Trinity", except the final four, which are termed "Sundays before Advent". In the Episcopal Church (United States), it is normal to refer to Sundays after Epiphany and Sundays after Pentecost (not Trinity).
The total number of Sundays varies according to the date of Easter and can range anything from 18 to 23. When there are 23, the Collect and Post-Communion for the 22nd Sunday are taken from the provision for the Third Sunday before Lent.
Ordinary Time is called "ordinary" not because it is common but simply because the weeks of Ordinary Time are numbered.
The Revised Common Lectionary has been subsequently adopted by many English-speaking Protestant denominations such as the Church of Scotland and various Lutheran and Reformed churches. It has also been adopted by some Old Catholic churches and is widely used throughout the Anglican Communion, for example by the Church of Ireland, the Scottish Episcopal Church, the Church in Wales, the Episcopal Church (US) and the Anglican churches of Canada, Australia, Aotearoa/New Zealand and Polynesia, Melanesia, the West Indies, Central Africa, and Southern Africa. In the Church of England the two-year Sunday Lectionary of the Alternative Service Book 1980 was replaced in 2000 by an adapted version of the Revised Common Lectionary in Common Worship.
For many Protestant church traditions, the season of Epiphany extends from 6 January until Ash Wednesday, which begins the season of Lent leading to Easter.
