Although the feasts of St. Lawrence and the Nativity of the Blessed Virgin Mary officially still had simple octaves, by the 20th century they had all but vanished as higher-ranking feasts were added to the calendar. The octave day alone of St. Lawrence was still commemorated during the mass of St. Hyacinth. The entire octave of the Nativity of the Blessed Virgin Mary was impeded, but The Most Holy Name of Mary was celebrated during the octave and The Seven Sorrows of the Blessed Virgin Mary was celebrated on the former octave day.
