A hoax that fools people into thinking it is the same day that Marty McFly travels to in Back to the Future has struck for a second time.

Social media was abuzz with news that June 27 was the day that Christopher Lloyd's Doc Brown and Michael J Fox's Marty McFly set their time machine car the Delorean to travel to in the hit 1985 film.

But the real date, revealed by Mashable.com, is October 21, 2015.

The rumours were gold for Facebook and Twitter users, where thousands of people shared a doctored image from the car's time machine showing the June 27 date.

'Back to the Future' even began trending on Twitter, NME.com reported.

The same prank fooled people a couple of years ago, but the new prankster told Mashable his hoax was "an accident".

Social media manager Steve Berry said it was done to promote the release of the Back to the Future trilogy on blu-ray.

He thought everyone would remember the original hoax and find the new one funny.

"We promoted the image fully confident in the knowledge that everyone was familiar with the original hoax from a couple of years ago," Berry told Mashable.

"We figured that no one would fall for the same joke twice, so the caption was deliberately replicated word-for-word so people would get the reference."
