I've noticed several of my Facebook friends have posted a picture of the date displayed inside the DeLorean time machine in 'Back to the Future II' as June 10, 2015. That's NOT CORRECT!

In fact, there's a tumblr page you can view HERE that is dedicated to making every date look like the date to which Marty travels in the future.

The real date will certainly be celebrated with more fanfare than a few friends posting a photo shopped picture; it's October 21, 2015.
