General Roman Calendar of 1960
This article lists the feast days of the General Roman Calendar as approved on 25 July 1960 by Pope John XXIII's motu proprio Rubricarum instructum and promulgated by the Sacred Congregation of Rites the following day, 26 July 1960, by the decree Novum rubricarum. This 1960 calendar was incorporated into the 1962 edition of the Roman Missal, continued use of which Pope Benedict XVI authorized in the circumstances indicated in his 7 July 2007 motu proprio Summorum Pontificum.
Novum rubricarum replaced the former classifications of Doubles, Semidoubles, and Simples with I, II, and III class feasts and commemorations. It removed a few feasts, in particular duplications such as the Feast of the Cross (3 May and 14 September), the Chair of Peter (18 January and 22 February), Saint Peter (1 August and 29 June), Saint John the Evangelist (6 May and 27 December), Saint Michael (8 May and 29 September), and Saint Stephen (3 August and 26 December).
This calendar is distinct from the General Roman Calendar of 1954 in that it also incorporates the changes made by Pope Pius XII in 1955, which included the reduction of octaves to three only, those of Christmas, Easter and Pentecost. See General Roman Calendar of Pope Pius XII.
