"When's Google’s birthday? I'm not sure even we know – we've celebrated on September 7th, 8th, 26th, and, most recently the 27th. Still, while there’re some differing opinions about when to bust out the candles and cake, one fun fact is that our first doodle was posted even before Google was officially incorporated," says Google.
You can find Google's previous birthday doodles on this page.
Happy Birthday, Google!
