The above is a photograph of the Calendar page from the June 1981 newsletter of the $$PX British District. It is interesting to compare then and now. Below is a screen- capture from the current newsletter of the $$PX District of Great Britain, Ireland and Scandinavia showing the calendar for the month of June.
One sees the difference in the liturgical books in use. The newsletter from 1981 clearly shows the use of the pre-1962 books in the British district. The Octaves of the Ascension, Corpus Christi and the Sacred Heart are all there. Notice too the traditional classification of the liturgical days as Doubles of the First Class, greater-doubles, doubles, semi-doubles and simples. One can also see three different grades of Octave.
It is interesting too to see that some of the Horae Minores, namely Prime, Sext and Compline, were publicly celebrated on week-days too back in those days.
