according to my http://www.livejournal.com/birthdays.bml

there are 87 unique person-birthdays;

there are four birthdays on 11/11/xx;
there are three birthdays on 10/20/xx (I counted four until "Oh Wait Hey Car Has At Least Two LJs");
there are three birthdays on 11/25/xx;
there are three birthdays on 06/19/xx;
there are three birthdays on 05/18/xx.

According to these- and only these- data,
You have an 18.4% chance to have been born on one of those five days.

Divide that by five and you get a 3.68% chance to have been born on one of those days.

However, in a completely-random, completely-equal-chanced sort of system, you'd only have a 0.274% chance to be born on a given day.

So with this data set, the five days I listed above have a 13.43-times-greater "birth-happening-chance" than would be predicted by a completely random model.

87 is a small sampling of data-points for a system which allows for 365.25 different outcomes,
but I'd say that that 13.43 is a pretty significant figure.




So, uh,
happy birthday, kids c.c
YOU FELL INTO THE BLACK HOLE OF SCIENCE.

Well, if your friends tend to be rather odd people, then it makes some sense. Nonconformists and eccentrics rarely display socially typical, expected, predictable behaviour, after all. Thankfully! * laughs *

I love how communities (can) have birthdays.

No, communists can't have birthdays, because they're not allowed to "have" anything, you cyan-oh capital-ie.

The high volume of mid-November birthdays can be easily explained:

Mid-November is 9 months after Valentine's Day.
