Liturgical Year 

2024 Liturgical Calendar

The Archdiocese of Santa Fe observes five solemnities designated as Holy Days of Obligation with the obligation to participate in Mass: 

• Mary, Mother of the Lord (January 1-the obligation to participate in Mass is abrogated)
• The Ascension of the the Lord (May 9)
• Assumption of the Blessed Virgin Mary (August 15)
• All Saints Day (November 1)
• Immaculate Conception (December 8 - the observance is transferred to Monday, December 9, and there is no obligation to participate in Mass)
• The Nativity of the Lord (December 25)  

• When January 1, August 15, or November 1 fall on a Saturday or a Monday, the obligation to participate in Mass is abrogated.
• When December 8 falls on a Saturday or a Monday, the obligation to participate in Mass remains because Mary, under the title of the Immaculate Conception, is the patroness of the United States.
• When December 8 falls on a Sunday of Advent, the observance is transferred to Monday, December 9, and there is no obligation to participate in Mass.
• December 25, The Nativity of the Lord, is always a holy day of obligation.
