The best choice to know where in your missal to go to for a particular day, Sundays and holy days in particular, is to buy a liturgical calendar for the Tridentine Mass at your local bookstore. You can also order one from a vendor such as Angelus Press, which is where I get mine and the ones I give to my family. Now if you can’t afford to do that because of the economy a place I found on the internet is https://www.virgosacrata.com/catholic-calendar.html. This should help kick the year off right for everybody.
