May. 25 Memorial of the Blessed Virgin Mary, Mother of the Church; Memorial Day (USA), Memorial
In 2018 Pope Francis decreed that the ancient devotion to the Blessed Virgin Mary, under the title of Mother of the Church, be inserted into the Roman Calendar. The liturgical celebration, B. Mariæ Virginis, Ecclesiæ Matris, will be celebrated annually as a Memorial on the day after Pentecost.
