Google's Founding Anniversary

What Is Google's Founding Anniversary?

September 27th is celebrated as "Google's Founding Anniversary" — the day Google, the company behind the world's most widely used search engine, marks as its own birthday.

Why September 27th, of All Days?

Curiously, September 27th isn't Google's actual incorporation date. So why has it become the company's official birthday?

• Company founded: Google was founded in 1998 by Larry Page and Sergey Brin
• Domain registered: The "google.com" domain was registered on September 15, 1997
• Incorporation: Google was formally incorporated on September 4, 1998
• Origin of the "birthday": Google first posted a founding-anniversary Doodle on September 27th, and since 2006 the company has celebrated this date as its official birthday every year

Choosing a Symbol Over a Strict Date

Rather than insisting on the exact legal founding date, Google has embraced a symbolic date to celebrate each year — a flexible, characteristically Google approach.

Ways to Mark the Day

• Look into the founding story of Google and its co-founders, Larry Page and Sergey Brin
• Revisit the evolution of the Google logo and past Doodles
• Take a moment to appreciate the search engine you use every day without a second thought
• Reflect on how much technology has evolved since Google's earliest days

A Day to Reflect on the Search Engine That Changed the World

Google's Founding Anniversary isn't tied to a strict legal date — it's a symbolic day the company itself chose to celebrate. September 27th is a moment to pause and appreciate the history of the search engine that has become woven into our everyday lives.
