September 12 - The celebration of the Feast of the Holy Name of Mary comes from a city in Spain, New Castile, for the first time in 1513. The celebration was abolished by Pope Pius V in 1570 and restored by Pope Sixtus V, and celebrated on September 17.

The celebration originally took place only in this city, but then spread to the Diocese of Toledo and then throughout Spain. Pope Clement X authorized the government of Naples to celebrate the Holy Name of Mary in 1671. The Diocese of Milan celebrated it on September 11 and others on September 22. This celebration did not take place in Rome until 1683, at the time of Innocent XI, to give thanks to God on the occasion of the liberation of the city of Vienna under Turkish occupation on September 12, 1693. Pope Innocent XIII proclaimed this celebration of the Holy Name Mary to the Universal Church in 1721, and Pope Pius X moved the date to September 12 during the great reform of the Roman Breviary.
