Every September 27, searches for “Google’s birthday” rise again — and the date creates a reasonable question. Google Inc. was incorporated on September 4, 1998, so why does the company celebrate on September 27? Google has acknowledged the mismatch itself. The company says the exact birthday is debatable, but it has celebrated September 27 for more than a decade, traditionally with a Google Doodle and anniversary features.

How old is Google in 2026?

Google is celebrating its 28th birthday in 2026. Google Store’s current U.S. birthday page explicitly calls it the company’s 28th birthday and ran a birthday promotion from September 13 through September 27, 2026.

The age comes from 1998, the year Google became a company and moved from a university research project toward the business and technology platform people know today.

Why September 27 instead of September 4?

Google’s own company blog addressed this directly in 2018. It noted that Google Inc. was incorporated on September 4, but said the company had been celebrating its birthday on September 27 for more than a decade.

That means September 27 is best understood as Google’s chosen public birthday rather than the legal incorporation date. The company has repeatedly used September 27 for anniversary Doodles, retrospectives and product celebrations.

Google started before the garage

The origin story begins at Stanford University, where Larry Page and Sergey Brin worked on a search project designed to rank information on the rapidly growing web. Their approach focused heavily on relationships between pages rather than treating every page as an isolated document.

By 1998, the project had attracted attention beyond the university. Google’s official company history says Sun Microsystems co-founder Andy Bechtolsheim wrote a $100,000 check to Larry and Sergey in August 1998. That investment helped the newly formed team move out of the university environment and into its first office.

The famous Google garage

Google’s first office was a garage in Menlo Park, California, owned by Susan Wojcicki, who later became an early Google employee and eventually led YouTube. Google has recreated the garage in Street View as part of its anniversary history.

The space was modest: desktop computers, improvised furniture, colorful details and a small team. Google’s 2018 retrospective described the company expanding from the garage into rooms in the house as the team grew.

Where did the name Google come from?

Google says its name was inspired by “googol,” the mathematical term for the number 1 followed by 100 zeros. The name matched the founders’ goal of organizing an enormous and rapidly expanding amount of information.

Search was the original product

Google’s central mission was to organize the world’s information and make it broadly accessible and useful. Search became the product that defined the company, but the business eventually expanded far beyond a search box.

Over time, Google built or acquired products in maps, email, browsers, video, mobile operating systems, cloud computing, advertising, productivity software, hardware and artificial intelligence.

The first Google Doodle was also in 1998

Google’s company history notes that the first Doodle appeared in 1998. It was a playful modification of the logo connected to the Burning Man festival and served as an informal signal that the team was away.

Doodles later became a recurring part of Google’s identity, marking holidays, scientific achievements, cultural figures, anniversaries and the company’s own birthday.

Why the birthday date became part of Google culture

For a company built around organizing precise information, having a birthday that is not the incorporation date is unusual. Google has leaned into that ambiguity rather than trying to rewrite the historical record.

Its 2018 post called the anniversary “20(ish) years of Google,” openly acknowledging that September 1998 contains several plausible milestones. The September 27 celebration is therefore a tradition layered on top of the legal and product history.

Google at 25: from Search to generative AI

On September 27, 2023, Google used its 25th birthday to look back at how Search had evolved. The company described the journey from answering basic web queries to a much larger collection of services and highlighted generative AI as part of the next stage.

That anniversary is useful because it shows how Google’s own framing changed: Search remained central, but AI increasingly became part of how the company described its future.

What is different at Google’s 28th birthday?

By 2026, Google’s consumer product story is deeply tied to Gemini. The company’s current U.S. birthday promotion highlights Pixel phones and other hardware through the lens of Gemini-powered features, including photography and hands-free assistance.

This does not mean Search has disappeared. It means the company is now trying to connect Search, Android, Pixel hardware, cloud infrastructure and AI models into one larger ecosystem.

Google’s 2026 birthday promotion

For its 28th birthday, Google Store in the United States offered temporary discounts on selected Pixel phones, Pixel Buds and Fitbit-related products. The promotion was scheduled to end on September 27, 2026 at 11:59 p.m. Pacific Time.

Because those offers are time-limited, they should not be confused with the historical reason for the birthday. The date remains the annual tradition; the individual store promotions change each year.

Is September 27 Google’s legal founding date?

No. Google’s own account says Google Inc. was incorporated on September 4, 1998. September 27 is the date the company has chosen for its public birthday celebrations.

Was Google founded in a garage?

The company’s earliest search work began at Stanford, not in the garage. The garage became the first office after the new company received early funding and moved into a dedicated workspace. So “Google was founded in a garage” is a simplified version of a longer story.

Who owned the garage?

The Menlo Park garage belonged to Susan Wojcicki. She later joined Google as an early employee and went on to become CEO of YouTube. Google has preserved the garage story as a major part of its early-company history.

Why this trend returns every year

Google is one of the most widely used technology brands in the world, and its homepage historically gives its birthday unusually high visibility through Doodles and anniversary experiences. That naturally drives people to search for the company’s age, founders and the reason behind the September 27 date.

A timeline of the early milestones

  • Stanford years: Page and Brin develop their approach to web search.
  • August 1998: Andy Bechtolsheim writes a $100,000 check supporting the new company.
  • September 4, 1998: Google Inc. is incorporated.
  • 1998: the team moves into the Menlo Park garage.
  • September 27: becomes Google’s long-running public birthday tradition.
  • September 27, 2023: Google celebrates 25 years of Search and emphasizes AI in its future.
  • September 27, 2026: Google celebrates its 28th birthday.

Bottom line

Google celebrates September 27 because it became the company’s established public birthday tradition, not because that was the legal incorporation date. The legal milestone was September 4, 1998. The story stretches from a Stanford search project and a $100,000 early investment to a garage office, global Search, Android, Maps, YouTube, cloud services and today’s Gemini-centered AI strategy.

Google’s own historical sources include its “20(ish) years” explanation, the original garage retrospective, and its 25th-birthday retrospective.
