You will not find the changing of Saint’s feast days in the documents of VII. I am unaware of any specific Church document that lists all of the changes.
Alot of the Saints still have the same feast days. Some were moved or removed to make way for nore recently canonized Saints. And I believe that others were moved so that they ended up outside of the season of Lent.
One thing that I find very helpful in comparing the 2 Liturgical Calendars, especially when it comes to feast days of the Saints, is a
calendar put out by Tan Books. It covers both the Nouvs Ordo and Tridentine Liturgical years. And it also has some feasts which were historically celebrated but are no longer celebrated in either rite.
