According to the Catholic Encyclopedia, when the Galician and Roman practices were combined, the September date, for which the Vatican adopted the official name "Triumph of the Cross" in 1963, was used to commemorate the rescue from the Persians and the May date was kept as the "Invention of the True Cross" to commemorate the finding.[43] The September date is often referred to in the West as Holy Cross Day; the May date (See also Roodmas.) was dropped from the liturgical calendar of the Catholic Church in 1960 when the Roman Breviary was reformed by Pope John XXIII.[44] The Orthodox still commemorate both events on September 14, one of the Twelve Great Feasts of the liturgical year, and the Procession of the Venerable Wood of the Cross on 1 August, the day on which the relics of the True Cross would be carried through the streets of Constantinople to bless the city.[45]
