My theory is that he was moved to accomodate the Korean martyrs on the 20th.
St. Francis Mary, pray for us!
I suppose since the liturgical observance of the Korean Martyrs is an obligatory memorial they'd take priority but we've had through the centuries more than one saint on a given day. For example, on the 23rd there's the "Finding of the Body of St Clare" and "St Pio." Which takes priority. For the Church universal it's St Pio, but a Franciscan House may or may not have a choice? The old days of commemorating more than one saint was fine, methinks.
