Google Celebrates Its 28th Birthday on September 27, 2026

Google celebrates its birthday on September 27, and today, September 27, 2026, marks its 28th birthday. The occasion is being marked with a nostalgic Doodle on the Google homepage.

🎂 The Birthday vs. The Incorporation Date

There's a well-known quirk: Google's official birthday celebration doesn't match its legal incorporation date.

• Celebrated Birthday: September 27. Google has consistently celebrated on this date since 2006.
• Official Incorporation Date: September 4, 1998. This is when Google Inc. was legally formed after receiving a $100,000 investment.

🤔 Why September 27?

The choice of September 27 is not tied to a single major company milestone. The most commonly cited reason is that Google aligned its annual celebration with this date starting in 2006 to mark the day it announced a record-breaking expansion of its web search index. Before settling on this date, Google celebrated on several different days in its early years, including September 7, 8, and 26.

🎨 The Birthday Doodle

To celebrate its 28th birthday, Google released a special Doodle that features:

• A nostalgic, retro version of its original 1998 logo.
• An interactive historical trivia quiz for users to test their knowledge of Google's history.

The Doodle serves as a tribute to Google's origins as a Stanford University research project called "BackRub," before it was renamed "Google."
