But today is the first of the Ember Days of September... in the kalendarium of the 1962 Missal. I could easily look this up but haven't: for some reason the 1960/1962 folks observe the Ember Days of the season a week after the folks who follow the calendars of 1910 and 1939 do.
I did check at New Liturgical Movement, and Dr DiPippo's explanation is here. These are not the sort of details I'm liable to keep in mind but I do wish I had thought of this last week so I could've sorted out my 'response' to the calendars' nonsense. The discrepancy between the Traditional Rite celebrated before 1960 and it celebrated after only occurs sometimes.
The Ember Days of autumn are the Wednesday, Friday and Saturday of the third week of September, during which the book of Tobias is read; according to the traditional system of calculation, this year [2015, and this year, 2020] they will occur on the 16th, 18th and 19th. The system is also calculated so that the Ember days will always begin on the Wednesday after the Exaltation of the Cross.
In the 1960 revision, however, the first Sunday of the months from August to November is always that which occurs first within the calendar month. According to this system, the first Sunday of September is the 6th this year; the third will be therefore be the 20th, and the Ember Days will be the 23rd, 25th and 26th.
At Saint-Eugène (which in this is following the 1960 calendar), Holy Mass will be livestreamed at 1000. I still have to decide whether to simply repeat the fast etc from last week, modify it, or ignore it altogether. Thursday. I am catching up at the feed reader and see that Father Zuhlsdorf had posted this helpful explanation. Since I'm not a cleric bound to the recitation of the Office, I use the pre-1960/1962 texts; if at the day of Judgment, the divine Majesty makes known to me that I haven't been participating in the Liturgy all these years, benedictus sit nomen eius. The two parishes in Veneta that observe the Traditional Rite do, both of them, in my limited experience, keep to the 1960/1962 texts.
Earlier, I listened to Ekvatoriaaltaevas (Equatorial Skies, according to the one machina, Equatorial Seas to the other-- we are evidently looking up the heavenly constellations from the equator?) on the Estonian Klassikaraadio; it is a part of Urmas Sisask's Tähistaeva tsükkel, his Starry Sky Cycle, performed by the pianist Yuko Yoshioka.
Now post Missam am listening to a concert performed on the 16th during the Berliner Festspiele Musikfest. St Hildegard, Binchois, Palestrina, Gesualdo, Lassus, Byrd, Victoria, Bach, Sheppard, Caldara, with Maestro Martin Baker improvising at the organ between the vocal works.
Am passing up a concert given by the European Workshop for Contemporary Music livestreamed from the 63rd International Festival of Contemporary Music in Warsaw for the RIAS Kammerchor concert (not a difficult choice!); they are using YouTube, which means I can listen later on, if the fancy takes me.
