What are the Holy Days of Obligation in the US?

In the US in 2026: Mary, Mother of God (Jan 1), Ascension (varies by diocese), Assumption (Aug 15), All Saints (Nov 1), Immaculate Conception (Dec 8), and Christmas (Dec 25). Some dioceses move Ascension to the following Sunday.

Do I have to go to Mass if a Holy Day falls on a Saturday or Monday?

In the US, the obligation is dispensed when Mary Mother of God, Assumption, or All Saints falls on a Saturday or Monday. Immaculate Conception and Christmas remain obligatory regardless.

Is missing a Holy Day of Obligation a mortal sin?

Missing Mass on a Holy Day of Obligation is grave matter. Whether it constitutes mortal sin depends on full knowledge and deliberate consent. If you genuinely could not attend due to illness, work, or distance, it is not a sin. Confession is the path forward if it was deliberate.

Can I attend a vigil Mass for a Holy Day?

Yes. A Mass celebrated the evening before (usually after 4pm) fulfills the obligation for the next day's holy day.

Finding a Mass near you

Use a Mass times directory or Faith Common's parish profiles to find vigil and day-of Mass times. Most parishes add 1–3 extra Masses on holy days.

What to do if you genuinely can't make it

Illness, work that cannot be moved, caring for someone, or distance excuses the obligation. If it was deliberate, the path forward is sacramental confession. Holy days are gifts, not burdens — they exist to mark the great mysteries of the faith.
