I was born on the 28th. July.

How many people do I have to invite to my party to ensure that, on average, there should be two people present with the same birth date?

Let's assume there are 365 days to the year.

Have a guess and write it down and then run this program. You will be very surprised.

It is a .exe file but all is OK. You can always find me!

Run it from the current location and save it later if you wish.
