Editing Ordinary Time (section)

== Roman Rite ==
In the ordinary form of the [[Roman Rite]], the last day of Christmas Time is the Sunday after the [[Epiphany (holiday)|Solemnity of the Epiphany]], or the Sunday after January 6 in places where Epiphany is moved to always occur on a Sunday.  Ordinary Time begins the following Monday, and the weekdays that follow are reckoned as belonging to the first week of Ordinary Time.  The [[Feast of the Baptism of the Lord]] is usually celebrated on the last day of Christmas Time, but if it is displaced to Monday due to Epiphany being celebrated on January 7 or 8, the Feast of the Baptism falls in Ordinary Time instead.<ref name="UNLY332">{{Cite web |title=''Universal Norms on the Liturgical Year'', 33 |url=http://www.liturgyoffice.org.uk/Calendar/Info/GNLY.pdf |access-date=June 18, 2018}}</ref><ref>{{Cite web |title=Lectionary: Movable Feasts during the Christmas Season |url=https://catholic-resources.org/Lectionary/Overview-Christmas.htm |access-date=2024-09-09 |website=catholic-resources.org}}</ref>

Because Ordinary Time begins on a Monday, there is no day called the "First Sunday in Ordinary Time".  Instead, the lowest-numbered Sunday is called the Second Sunday in Ordinary Time. This block of Ordinary Time continues through the Tuesday that immediately precedes [[Ash Wednesday]].<ref name=":0">{{Cite web |last=Sloun |first=Father Michael Van |date=2020-06-19 |title=Ordinary Time |url=https://thecatholicspirit.com/commentary/hotdish/ordinary-time/ |access-date=2024-09-10 |website=TheCatholicSpirit.com |language=en-US}}</ref>

Ordinary Time resumes on the Monday after the Solemnity of [[Pentecost]].  The two Sundays following Pentecost are the [[Trinity Sunday|Solemnity of the Most Holy Trinity]] and the [[Feast of Corpus Christi|Solemnity of the Most Holy Body and Blood of Christ]], which despite being part of Ordinary Time, are not numbered.<ref name=":0" />  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 last day of Ordinary Time is the day before the [[First Sunday of Advent]].  The last Sunday of Ordinary Time is the [[Feast of Christ the King|Solemnity of Christ the King]], with the Sunday before that being the Thirty-Third Sunday in Ordinary Time, with the ordinal numbers counting backwards from that point.<ref name=":0" /> 

Due to the configuration of the calendar year, Ordinary Time may have a total of either 33 or 34 weeks.  As a [[mnemonic]], if the First Sunday of Advent is in November, the previous liturgical year's Ordinary Time will have 33 weeks.  If it falls on December 2 or 3, it will have 34 weeks.  However, if it falls on December 1, the previous year's Ordinary Time will have 34 weeks only when it is a leap year.<ref>{{cite web|url=https://www.gcatholic.org/calendar/2022/General-A-pt.htm |archive-url=https://web.archive.org/web/20221009095525/http://www.gcatholic.org/calendar/2022/General-A-pt.htm |url-status=dead|title=Calendário Litúrgico: Calendário Romano Geral|archive-date=October 9, 2022}}</ref>  In a year where Ordinary Time has 33 weeks, the omitted week is the one between the weeks immediately surrounding Lent and Easter Time, which varies with the [[date of Easter]].  This is because the weeks always count forward from the first week at the beginning of Ordinary Time, and separately backwards from the thirty-fourth week at the end of Ordinary Time.

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.

=== Solemnities, feasts and commemorations ===
The celebration of an Ordinary Time weekday gives way to that of any [[solemnity]], feast, or obligatory [[memorial (liturgy)|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 Ordinary Time are:<ref>{{Cite web|url=https://www.liturgyoffice.org.uk/Calendar/Info/GNLY.pdf|title=Universal Norms on the Liturgical Year and the General Roman Calendar: Table of liturgical days according to their order of precedence, p. 13}}</ref>
