What is today?
As Jeff Miller points out, in much of the English-speaking world it's the Feast of the Rant that today is not Ascension Thursday. As he says:
Last year the Bishops of England and Wales joined the U.S. in moving the Ascension to Sunday so I welcome those who live their to commiserate with us. On the "Feast of the Rant that today is not Ascension Thursday" it is traditional for bloggers in these countries to gripe about the movement of this feast especially newer bloggers who have not yet posted on this subject.
(I think, though I'm not sure, that it's also moved in Australia and New Zealand. It's definitely moved in Canada.)
Of course, not all Catholics suffer with this. Even though we live in Canada, since we attend a Ukrainian-rite church, we get to observe Ascension Thursday on . . . Ascension Thursday. I'll try not to rub it in, though.
