Following a request for information the Bishops' Conference of England and Wales submitted a dubium to the Pontifical Commission Ecclesia Dei which confirmed that in the Roman Rite, whichever Form of the liturgy is being celebrated, the Holydays of Obligation are held in common.
The Latin Mass Society sought further clarification from the Pontifical Commission which confirmed that In accordance with nn. 356-361 of the Rubricae Generales Missalis Romani of 1962, it is appropriate to celebrate the external solemnity of certain Holy Days on the Sunday to which they have been legitimately transferred by the Episcopal Conference. It further confirmed that it is legitimate to continue to celebrate the Mass and Office of these feasts on the days prescribed in the 1962 Calendar though there is no obligation for the faithful to attend Mass on those days.
