No, there isn't. There's a very, VERY high chance, but not 100%. You need 367 people to have a 100% chance of that. (And that's assuming we only care about the day and month, not the year. If you care about the year too, it gets even trickier.)


That's still not a 100% chance. You can't have a 100% chance with a random group.

Literally no way 367 people can have different birthdays.


Wait, yes, you are right. My bad, misread the post.
