Enjoy the day, because the Viking calendar claims the world is about to end.

As USA Today reports, old Nordic folklore alleges that three freezing winters with no summers in between signal the end of the world. Thus, Ragnarök—also known as the "Twilight of the Gods"—is upon us. Maybe. 

Feel free to scoff at this just like the "Mayan apocalypse," but there are some people in York, England who playful, yet serious about it. The Jorvik Viking Center is celebrating with its Viking Festival, complete with a countdown on its website. It's fun and cool to make an event out of the end of the world, but these folks are really into this stuff.

"This really is an event that should not be underestimated. In the last couple of years, we've had predictions of the Mayan apocalypse, which passed without incident, and numerous other dates where the end of the world has been penciled in by seers, fortune tellers and visionaries," festival director Danielle Daglan explained.
