The collects used can be those Pro Papa in Orationes diversae, as they are the same. There is no commemoration in the Divine Office.

These Mass collects will be added in like manner each year on May 18 for the anniversary. This time of year they could be impeded by Pentecost, Trinity Sunday, or the Ascension, in which case they would be used on the next day which is not first class (RG 363).
In cathedrals and parishes with a chapter of canons or equivalent religious (i.e., collegiate churches), the II class votive Mass is celebrated instead (RG 362), as also by consent of the Ordinary in individual churches holding special celebrations in honor of the Sovereign Pontiff (RG 365).
