World population right this moment = 6, 908, 354, 380
No. of days in a year = 365
6, 908, 354, 380 ÷ 365 = approx. 18, 926, 998
So you share your birthday with nearly 19 million other people in the world.
Not so special now, eh?
I spent a stupidly long while just watching the world population clock live, seeing the numbers rise and rise... It's incredible. Thousands of babies have been born since I began this very post.
