It's pretty bad form to give the doomsday algorithm and not give credit to John H. Conway who invented it.

Pretty sure he was not when I posted my comment. It currently says "more on him at the end" and that bit seems not to have been written yet. Also there are two mathematicians called "John Conway" so it's good form to say "John H Conway".
