One of the most important changes, immediately visible to those who do not pray the Divine Office, was the ranking of Sundays: whereas ordinary Sundays previously had given way to all feasts of the rank of "double", of which there were roughly two hundred in the general calendar alone (among others, virtually every bishop or monastic saint of the 2nd millennium that had a feast at all had a double feast), they would in the future have precedence over them except for feasts of the first and second class and of the Lord, of which there were considerably fewer (marking the time when the liturgical color of green came to become the usual color rather than a rare exception). In addition, by the motu proprio "Ab hinc duos annos" of 23 October 1913, Pope Pius X added to his reform of 1 November 1911: no feast was to be fixed "permanently" to a Sunday except the Holy Name of Jesus and the Blessed Trinity (later, the feasts of the Holy Family and of Christ the King would be added). The Sunday office would only be superseded by sufficiently high-ranking feasts that happened to occur on their dates. The octaves were equally simplified.
