This is something I've been meaning to experiment with for ages, but never got round to. I've just been reminded of it, because someone posted on a thread elsewhere with the assumption that "birthdays are randomly distributed" - which I've always assumed they're not. For a start, there's always a bit of a clump of birthdays round February/March, which I've always blamed on people having early summer holidays in June.

Now, I'm assuming that unlike, say, musical taste, incidence of birthdays among my friends list will at least be representative of the population as a whole. If not, then we're into the suggestion that being born in a particular month predisposes you to particular behaviours and that smacks of astrology, so I don't like it.

(Yes, I know there are other non-astrological factors which might be relevant, but let's give it a whirl, shall we?)



You're getting no tickyboxes for this, dammit, it's radio or nothing. I refuse to allow people to be born in more than one month.

Indeed :)

Though you've reminded me that actually the distribution of birthdays wouldn't be expected to be the same in each month - the chance of being born in, say, August isn't 1/12, it's 31/365 or 31/366, depending.

Dammit, leap years are going to make this more awkward than I was expecting.

so maybe just say "(days in the month)/365.25" and count February as having 28.25 days ?
