I have no idea how that works since the odds are 1 in 365 but ill go with it.

30th May


The odds aren't 1 in 365, that would be for a person chosen at random to have the same birthday. I can't be bothered to work the odds out atm, but it's the chance of any of the 55 people sharing a birthday.
If you guys want the probabilities.

I guess it means of someone in the room sharing a birthday with someone else in the room, rather than you specifically?

I don't know though, I try to avoid maths as much as possible :colonhash:
