Any diehard Back to the Future fan knows that October 21, 2015, is “Back to the Future Day,” the date that Marty McFly and Doc Brown travel to the future in the second film of the trilogy. Or wait, is it July 5, 2010? Or July 6, 2010? Or June 27, 2012? You may have seen conflicting photos on your Facebook page over the years of random future dates Doc and Marty traveled to from 1985, all splayed across the dashboard display of their time-traveling DeLorean. These posts you’ve seen? They’re a pack of lies. Rest assured, Back to the Future’s 30th birthday is this year, and the real Back to the Future Day on October 21, 2015, is finally happening.
