I must hand it to our friends at Rorate, who are always on top of this stuff.
Today is the 50th “birthday” of the 1962 Missale Romanum!
As per Rorate:
The Decree of the Sacred Congregation of Rites establishing the 1962 edition of the Missale Romanum was promulgated exactly 50 years ago today: June 23, 1962, a few months before the opening of the Second Vatican Council and with all rubrics and classifications fully aligned with the Codex Rubricarum promulgated along with the motu proprio Rubricarum Instructum of 1960.
And because it is the Vigil of my Name Day, I am glad to have received a nice box of Macanudo cigars from one of you readers. I shall enjoy one in honor of this festive occasion!
UPDATE 24 June:
If yesterday was the day of the Missal’s promulgation, then today could be the anniversary its “First Mass”. If it was signed and promulgated on 23 June, then it came into force after most priests in Rome had said their morning Masses. Thus, today could have been the first day of its use. No? Also, in 1962, 24 June was a Sunday. It seems appropriate that Pope John would want it to go into force on a Sunday which was also the Feast of the Nativity of John.
