The Paulist Press Ordo spells it out succinctly.
"Regarding the Ascension of the Lord, the ecclesiastical Provinces of Boston, Hartford, New York, Newark, Omaha, and Philadelphia have retained its celebration on the proper Thursday; all other Provinces have transferred this Solemnity to the Seventh Sunday of Easter."
Thus, it is a holy day of obligation if you live in one of those Provinces listed. Ascension Thursday becomes Ascension Sunday for the rest of us and tomorrow is just a regular Easter weekday celebration.
Please do not miss the opportunity to pray a novena simply because the Solemnity has been moved to Sunday for most of us. The days between Ascension Thursday and the Solemnity of Pentecost are looked upon as the time when the original novena took place. Our Blessed mother and the disciples gathered together in prayer awaiting the outpouring of the Holy Spirit.
Your novena should begin on Friday, May 6, and go through the following Saturday. This time of preparation will bring great blessing to you as we celebrate Pentecost on Sunday, May 15. Let the power of the Holy Spirit impact your life in a magnificent way during these final days of Easter.
