Christi Himmelfahrt
The days from the Ascension of Our Lord to the Vigil of Pentecost exclusive became feriae of Eastertide (in the Simple rite); the Mass was to be that of the Feast of the Ascension, but without the Credo and the special Communicantes (even on the Friday before Pentecost, where hitherto the Mass of the Sunday had to be taken). The days of the suppressed Octaves of Corpus Christi and the Most Sacred Heart of Jesus became feriae per annum.
