The ferial days in Paschaltide are IV Class, so when a III Class feast occurs on the calendar, no commemoration is made of the ferial office.
April and May are months par excellence in the traditional Dominican sanctorale. April contains the feasts of St. Vincent Ferrer (April 5), Our Lord's Most Holy Crown of Thorns (April 24), St. Agnes of Montepulciano (April 20), St. Louis de Montfort (April 28), St. Peter Martyr (April 29) and St. Catherine of Siena (April 30). May starts off with St. Pius V (May 5). Then we have the Feast of the Blessed Virgin Mary Mediatrix of All Graces (May 8), St. Antonius (May 10) , Blessed Imelda (May 13), the Transfer of Our Holy Father St. Dominic (May 24), and finally Bl. William and his Companions (May 29).
