I read this article on the internet that there is 6 billion people in the world so at least 3 people should have your birthday. So lets see if someone has the same birthday as me (doubt it). My b-day is December 21st, 1994
October 5th, my birthday was a week ago! xD 6 billion? If you divide that by 365, days in a year, you would come to about 16,438. So if that's correct, about 16,438 people share the same birthday as you!
