    I mean, he is "The Stats Guy" guy after all, this is his specialty. I say let his wife unstrain him for the moment.

    The well known mathematical formula is 1-(364/365)^(n*(n-1)/2). If i remember from university, to get a 50% likelihood of at least 1 match, you need 22-23 people.

    So doesn't seem so unlikely to find 2 regulars with the same birthday on here....

    Its a well known formula which i'm sure has more explanation online if you google. Told you it was boring ;-)

    It's boring cause there's too little! It feels like that takes birthdays at random as an assumption right? It's well known however that certain environments cause people to have more childbearing activities though, which cause more people to born around spring, relatively (9 months from summer-ish) or 9 months after a power outage

    You're absolutely right TheAtom, not random however, just equally likely to be any date. what you are talking about would only set to increase the probability of having the same birthday... and could easily be calculated with more input data

    Well, this topic certainly took a much different direction than I first thought.

    The_stats_guy for certain for certain! For people outside statistics random and equally likely is somewhat synonymous I guess but I get what you mean. It's interesting however that the chances are this high :)
