Today is St George’s Day, and some people in England are wondering why it does not appear in Universalis today. The reason is that this year there is a collision with Easter Saturday.
The Church’s calendar has to deal with collisions. Suppose, for instance, that the Annunciation, on the 25th of March, falls on Good Friday (as it did in 2016). Should we omit Good Friday that year, or omit the Annunciation? Or try to celebrate both at once?
