Q: Our parish church’s patronal feast is already a solemnity on the universal calendar. This year it falls on a Monday in Ordinary Time. We plan to transfer it to Sunday, as the General Norms for the Liturgical Year and Calendar permit (58).
The question I have is this: What do we do, both in terms of the Mass and of the Office on Monday? Do we repeat the solemnity or does Monday then become a ferial day? I can’t seem to find an answer in the GIRM, the General Instruction on the Liturgy of the Hours or in the General Norms for the Liturgical Year and Calendar.

A: I couldn’t find it either, so I consulted a friend at the Vatican, who chatted up a few of his colleagues.
This is not an official position, but a water cooler position: If the Mass is transferred, then the whole observance of the day is transferred, including the Liturgy of the Hours, and the weekday becomes a ferial day that year in your parish.
Their sense is that transferring a feast to a Sunday was not supposed to happen very often, as GNLYC 6 cautions: “Sunday excludes in principle the permanent assigning of any other celebration.”
