The Feast of the Ascension is a Holy Day of Obligation in the U.S. Most U.S. dioceses transfer the celebration to the following Sunday (7th Sunday of Easter), removing the Thursday obligation.
However, it remains a Thursday obligation in the Ecclesiastical Provinces of Boston, Hartford, New York, Newark, Omaha, and Philadelphia.
In regions like the Northeast and Nebraska, it is celebrated on Thursday, May 14, 2026, as a Holy Day of Obligation.
In most other parts of the U.S., the feast is observed on Sunday, May 17, 2026 (or the nearest Sunday), replacing the 7th Sunday of Easter, with no extra obligation.
