When is Google Birthday? 2015

Google is celebrating its 17th birthday with a commemorative Doodle harking back to the web of the 1990s. The image, featuring a retro, plastic PC, lava lamp and even 1998's "Google!" Logo, features on Google's homepage on September 27, which the internet giant has retroactively chosen as its birthday. However, not even Google seems to really know when it was formed. Since 2006, it has celebrated its birthday on September 27, but the year before that, had it as September 26.
