The Feast of the Most Holy Name of the Blessed Virgin Mary is an optional memorial celebrated in the liturgical calendar of the Catholic Church on 12 September.
Within the Eastern Orthodox Church, the feast is celebrated on 7 September in the Antiochian Western Rite Vicariate.
At Rome, one of the twin churches at the Forum of Trajan is dedicated to the Name of Mary (Santissimo Nome di Maria al Foro Traiano).
A number of religious orders such as the Cistercians and the Servites, customarily give each member "Mary" as part of his/her name in religion as a sign of honor and of entrustment to her.
[8] Its object is to commemorate all the privileges bestowed upon Mary by God and all the graces received through her intercession and mediation.
[6] In 1666 the Discalced Carmelites received permission to recite the Divine Office of the Name of Mary four times a year.
In the following year, to celebrate the victory, Pope Innocent XI added the feast to the Roman calendar, assigning to it the Sunday within the octave of the Nativity of Mary.
