In support of this thesis there would be an alleged error in reading the Gregorian calendar, introduced in 1582 to replace the Julian one. With the change, they were “lost” a few days a year, 11 to be precise, which added up together eight years of difference. “According to the Giuliano calendar, technically we are now in 2012,” wrote the scientist Paolo Tagaloguin in a series of tweets which were then deleted. But that was enough to circulate on social media – especially among conspiracy theorists – the unlikely theory that the final judgment day would therefore be Sunday. All that remains is to see if the phantom prophecy will come true.
