 The II class Vigils were those of the Ascension of Our Lord, the Assumption of the Blessed Virgin Mary, Saint John the Baptist, and Saints Peter and Paul; they took precedence over liturgical days of III or IV class.There was only one III class Vigil, that of Saint Lawrence, which had precedence only over IV class liturgical days.The Tridentine Calendar had many octaves, without any indication in the calendar itself of distinction of rank between them, apart from the fact that the Octave Day (the final day of the octave) was ranked higher than the days within the octave.
