If you put 20 people in a room, the odds of at least 2 of the people having the same birthday are suprisingly high.

Yup.

23 people gives you a 50% chance. IIRC 50 people means its 99% likely that 2 share the same birthday.

FWIW my birthday is July 14th. I'm gonna see my daddy for the first time on July 14th.
