Our patronal feast is Pentecost, so there is never a problem. Interesting question.

Do you have the option of transferring to either the previous or subsequent Sunday? Does it need to be one or the other?

Matthew, consider how the observances which are shifted to Sunday are treated: Epiphany, Corpus Christi, Ascension (in the un-biblically-minded provinces that shift it). Each of them is only observed once in the year.

That's a different kind of thing though.

The relevant section of the General Instruction of the Calendar regarding external celebrations of Feasts in the new rite:

58. For the pastoral advantage of the people, it is permissible to observe on the Sundays in Ordinary Time those celebrations that fall during the week and have special appeal to the devotion of the faithful, provided the celebrations take precedence over these Sundays in the Table of Liturgical Days. The Mass for such celebrations may be used at all the Masses at which a congregation is present.

This is an outgrowth of the practice of the external solemnity in the old rite. The last sentence is a specific expansion of the rule there, which was more restrictive. The festival is observed on Sunday, but not transfered in this case (and the office said privately is that of the day, not the observance).

Old rubric:

Votive Masses on the External Solemnity of Feasts

356. The external solemnity” of any feast means the celebration of the feast without an office, for the good of the faithful, either on the day on which the feast is impeded, or on a Sunday when the feast occurs during the week, or on some other established day.
...
360. One sung and one low Mass, or two low Masses, as votive Masses of the 2nd class, may be celebrated of the feast whose external solemnity is being held, except for the case specified in no. 358c.

Omitted from my quotation here is a middle part corresponding to the middle part of the revised norms about what feasts can be observed in this way which was also expanded...part of the general expansion of permissions.

This process is different than the process which has moved Corpus Christi etc. to Sunday which is covered in #7

7. In those places where the solemnities of Epiphany, Ascension, and Corpus Christi are not observed as holydays of obligation, they are assigned to a Sunday, which is then considered their proper day in calendar.

Note that last part, which is not present in #58.

I think parishes can overdo this though. My parish had the Feast of St Paul the first Hermit, St Margaret Mary and Our Lady of Chestahova all transferred to Sundays.
