Now approaching 8 Billion people on the planet, YES there are going to be people who look EXACTLY the same. That's why I say no big deal when somebody has the same birthday as me, duh? There area at least 22 million people with the same birtday as you, DUH what are the odds ? 8,000,000,000/365=22,000,000

Raji.maji.3 If you gather 25 people there is a 43,23% chance that none will have the same birthday (disregarding the year of birth), and a 56.77% chance that two people will share the same day and month. :-) To be 100% sure that two people would share the day/month, you'd have to have 367 people.
