In page Solemnity:

"

Among solemnities inscribed in the General Roman Calendar, those of the Lord have precedence over those of the Blessed Virgin and these latter over solemnities of other saints. Thus if, for instance, the Solemnity of the Sacred Heart of Jesus coincides with that of the Nativity of Saint John the Baptist or that of Saints Peter and Paul, it is these that are transferred to the next free day.[citation needed]
