It’s Google’s 11th birthday today, so here’s wishing them many more decades of success and may all their (and our) Google wishes come true!

To celebrate, Google has done a neat little trick by changing their logo to a version that has replaced “L” with an “11″.

There are some disputes about when Google’s birthday is considering Google.com domain was registered on September 15th, 1997. On the other hand, Google filed for incorporation in September 1998: the papers were filed on September 4th, but Google has been known to celebrate on both September 7th and September 27th.

Last year, Google released its logo on September 24th, this year however, they’ve released their logo to everyone today. Maybe, they’ve decided to officially adopt September 27th as their official birthday, you think?

Here are some of Google’s birthday logos from past years. Last year’s one is my favorite but i guess it needed to be a tad more decadent (excuse my unintentional pun) considering it’s been a decade.
