Feast of the Cross
"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).
