Well, I have no insider knowledge, but apparently Holy Week takes precedence over everything else, so any saint's day that happens to fall in Holy Week gets vaporised completely that year. Apparently the Irish, loathe to lose St Patrick's Day this year, celebrated it last Saturday instead.

I should own up and admit that I didn't actually know this until Pellinor told me a few days ago, and I then read it on the BBC website. It still entitled me to be nice and smug on Monday, though.
