No, the Vikings did not predict this date, but...

According to the Jorvik Viking Center in York, England, tomorrow is Ragnarök, the Twilight of the Gods (it remarkably coincides with the end of their Viking festival). So best of luck to you and yours. I'm realizing now that I don't have a sword or a mace or anything, so I'll probably be among the first to die. Considering everyone's going to be wiped out, though, I don't think it matters what order we go in.

oh, but here are some of my favorite things I've seen on fb about it:

"Wait, tomorrow is Ragnarök? You know, I'm not entirely sure what one wears to the Viking end of the world. I mean, I have nothing in the way of horned helmets or the like. Will a kilt suffice?" - Gregg

"Apparently Ragnarök is tomorrow and nobody told me. I do not have enough mead to put up with a barbarian apocalypse right now." - Caitlin

"BTW, if anyone needs a nice Viking young man to protect them from Ragnarok tomorrow... I'd offer my services, but it's not like I can actually protect you from ice giants.
So pray to Thor, I guess... Even though he's gonna die." - Buddy

"With Ragnarok (allegedly) coming tomorrow, please show a little bit of courtesy.
If you can't spell correctly, then please at least learn how to use commas and carriage returns. Especially if you're making an argument and expect others to read it and/or take you seriously." - Jason
