It’s St. Matthias Day . . . I think.

Normal people do not know it is St. Matthias Day.
Pious people, such as my humble self, look at a church calendar and know it is St. Matthias Day.
Liturgy geeks, of which I can be after too much wine or incense or Oxford, remember it’s a Leap Year and . . . oh boy, dating St. Matthias Day gets a bit complicated.  My calendar says it’s today, but if you want to get really serious about it, you could argue it’s tomorrow, and argue and…
A reader wrote in to ask why, in the traditional rite, the feast of St Matthias the Apostle is moved from February 24th to the following day every leap year. The answer lies in the very ancient Roman calendar, which is still part of the Church’s liturgy to this day; it is used in the calendars printed at the beginning of the Missal and Breviary, and in the Martyrology, the names of the days are still read out according to the Roman system.

In the Roman calendar, each month has three days which are called the Kalends, Nones and Ides; the first of these three is the first day of each month. In March, May, July and October, the Nones are on the 7th, and the Ides on the 15th; in all other months, they are on the 5th and 13th….
The Romans named the days of each month by counting backwards from these three points. Thus, Julius Caesar was killed on the day which we call March 15, but which they called “the Ides of March”; their name for the 14th was therefore “the day before the Ides of March.” As every Latin students knows, this system becomes difficult to keep track of because the Romans counted inclusively, not exclusively; therefore, the day we call “March 13” was called “three days before the Ides of March”, (not “two days before”), including the day itself, the day before the Ides, and the Ides themselves.
Hold on, it gets better.
When the Julian Calendar was instituted in 46 BC, establishing the regular leap day every four years, the leap day itself was added by counting “the sixth day before the Kalends of March” twice. From this, the Latin term for “leap year” is “annus bisextilis”, meaning “a year in which the sixth day (before the Kalends of March) occurs twice.” This term for leap year is still used in all the Romance languages, as in Italian “anno bisestile”, and was even adopted by the Greeks, (“disekto etos” in the modern language), even though the ancient Greeks had their own very different calendar….
When the feast of St Matthias came into the Roman Rite sometime between the 9th and 11th centuries, it was fixed to this “sixth” day before the kalends of March, which we call February 24. The precise reason for this choice is unknown, but it is surely not mere coincidence that nine other months have the feast of an Apostle or Evangelist within their last ten days, thus distributing them more or less evenly through the year. In a leap year, when there are two such days, Matthias’ vigil is kept on the first of the two, and his feast on the second.
The Apostles drew lots for this? It’s enough to give the pious a headache.
Well, I am taking the easy way out.  I am sticking to the Book of Common Prayer.  I did Morning Prayer for St. Matthias Day this morning.  So there.  
Hey, love or hate Thomas Cranmer, but the man knew how to keep it simple.
Anyway, have a blessed Feast of St. Matthias . . . or Eve of the same.
