From a reader:
I generally go to the Extraordinary Form of the Mass on Sundays but pray the Liturgy of the Hours.
I live in Los Angeles, CA, one of the areas where Ascension Thursday is moved to Sunday in the Ordinary form.
Since the EF doesn’t move Ascension Day to Sundays and I generally prefer to make use of the traditional calendar whereever possible, can I follow the LotH as written (i.e., Ascension Day on this coming Thursday) or am I obliged to follow what our local Ordinary has instructed (Ascension Thursday Sunday)?
Yes, there is rather a lot of confusion over the decision to transfer Ascension Thursday to become Ascension Thursday Sunday.
Lay people have no obligation to recite the Office, that is, the Liturgy of Hours or the Breviarium Romanum or any of the monastic variations, etc.
You may do as you wish in this regard if you are a layman.
I would also say that even clerics and religious who are bound to the Office can freely choose to use whichever office on Ascension Thursday, the office for the day in the Novus Ordo calendar or Ascension Thursday with the Breviarium Romanum. We have two uses of the Roman Rite and we may avail ourselves of them.
