Catholic Liturgical Calendar 2027: Year B, Ordinary Time and Season Dates

The Catholic liturgical year 2027 uses the Sunday Year B cycle, which runs from Nov. 29, 2026 to Nov. 21, 2027, according to the 2027 liturgical calendar of the United States Conference of Catholic Bishops (USCCB). Year C begins with the First Sunday of Advent on Nov. 28, 2027. Below are the season dates, the moveable dates for 2027 and a free one-page printable.

What are the liturgical seasons in 2027?

Season	First day	Last day	Color
Advent 2026	Sun., Nov. 29, 2026	Ends before Christmas, Fri., Dec. 25	Violet
Christmas Time	Fri., Dec. 25, 2026	Sun., Jan. 10, 2027 (Baptism of the Lord)	White
Ordinary Time, first part	Mon., Jan. 11, 2027	Weeks 1 to 5; the block ends Feb. 9	Green
Lent, Triduum and Easter Time	Wed., Feb. 10, 2027 (Ash Wednesday)	Sun., May 16, 2027 (Pentecost)	Violet, then white; red on Palm Sunday, Good Friday and Pentecost
Ordinary Time, second part	Mon., May 17, 2027	Sat., Nov. 27, 2027 (Weeks 7 to 34)	Green

Dates and weeks come from the USCCB 2027 calendar, including its Liturgy of the Hours table: Weeks 1 to 5 of Ordinary Time run Jan. 11 to Feb. 9, Lent, the Triduum and Easter run Feb. 10 to May 16, Weeks 7 to 17 run May 17 to July 31, and Weeks 18 to 34 run Aug. 1 to Nov. 27. The calendar does not print an end date for Lent on its own, so the table keeps Lent, the Triduum and Easter as one block. Colors are from the USCCB page on liturgical colors: violet for Advent and Lent, white for Christmas Time and Easter Time, green for Ordinary Time and red for Palm Sunday, Good Friday and Pentecost Sunday.

When does Ordinary Time start in 2027?

Ordinary Time starts Monday, Jan. 11, 2027, listed as the First Week in Ordinary Time, the day after the Baptism of the Lord on Sunday, Jan. 10, which ends Christmas Time. It stops on Ash Wednesday, Feb. 10, and the calendar resumes on Monday, May 17, the day after Pentecost, at the Seventh Week in Ordinary Time. By our count of the printed weeks, 2027 has 33 weeks of Ordinary Time: Weeks 1 to 5 and Weeks 7 to 34. The last, the Thirty-Fourth or Last Week, starts Monday, Nov. 22, after Christ the King on Sunday, Nov. 21.

The same calendar lists the weekday readings cycle as Cycle 1, for Jan. 11 to Feb. 9 and May 17 to Nov. 27, 2027. The page for Nov. 29, 2026 is headed “Year B – Weekdays I”, and Nov. 28, 2027 is “Year C – Weekdays II”.

Which liturgical dates move in 2027?

Date	Celebration	What the USCCB calendar says
Sun., Jan. 3	Epiphany (USA)	Sunday date for the United States
Sun., Jan. 10	Baptism of the Lord	End of Christmas Time
Wed., Feb. 10	Ash Wednesday	Lent begins
Fri., March 19	St. Joseph	Not moved
Sun., March 21	Palm Sunday	Red
Thu., March 25	Holy Thursday	Annunciation is not kept this day
Fri., March 26	Good Friday	Red
Sun., March 28	Easter Sunday	Date set in the principal celebrations list
Sun., April 4	Second Sunday of Easter (Divine Mercy)
Mon., April 5	Annunciation of the Lord	Transferred: “Since March 25 is Thursday of Holy Week (Holy Thursday), the Solemnity of the Annunciation of the Lord is transferred to Monday, April 5.”
Thu., May 6 or Sun., May 9	Ascension	May 6 in the provinces of Boston, Hartford, New York, Omaha and Philadelphia; May 9 in all other U.S. provinces
Sun., May 16	Pentecost Sunday	Red
Sun., May 23	Trinity Sunday
Sun., May 30	Body and Blood of Christ (Corpus Christi, USA)
Fri., June 4	Sacred Heart
Sun., Aug. 15	Assumption
Mon., Nov. 1	All Saints	Not a holyday of obligation this year; the obligation to attend Mass is abrogated
Sun., Nov. 21	Christ the King	Last Sunday of Year B
Sun., Nov. 28	First Sunday of Advent	Year C begins
Wed., Dec. 8	Immaculate Conception	Holyday of obligation
Sun., Dec. 12	Third Sunday of Advent	The Feast of Our Lady of Guadalupe is omitted this year

Three items are easy to miss. The Annunciation is transferred because March 25 is Holy Thursday. The All Saints obligation to attend Mass on Monday, Nov. 1 is abrogated this year, and the Feast of Our Lady of Guadalupe is omitted because Dec. 12 is the Third Sunday of Advent. For the 2026 holy day, see our Immaculate Conception story.

What color is each season, and when is rose used?

The USCCB page on the liturgical colors cites the General Instruction of the Roman Missal, no. 346, for rose on the Third Sunday of Advent and the Fourth Sunday of Lent. Counting from the calendar, those fall on Sunday, Dec. 13, 2026 and Sunday, March 7, 2027; the dates are our calculation from Advent’s start and from Ash Wednesday, Feb. 10. Red marks Palm Sunday, Good Friday and Pentecost Sunday, and the celebrations of the Lord’s Passion and of Apostles. White is also used for celebrations of the Lord (except of his Passion), of Mary and of the Angels.

How do Lent and Easter 2027 line up with the calendar?

Ash Wednesday is Feb. 10, the day after Mardi Gras on Feb. 9; our Lent calendar covers the weeks that follow. Palm Sunday is March 21, Holy Thursday March 25, Good Friday March 26 and Easter Sunday March 28; see what is open on Easter 2027 for the closures. The Easter date also has a when-is page, and you can mark the week on a March 2027 printable calendar or the 2027 printable yearly calendar.

What does the printable show?

The free one-page sheet numbers ten key dates on a 2027 calendar, with the season color named in the label and each date numbered, so it still reads in black and white. It is drawn from the USCCB calendar and colors page listed under Sources.
