We'll be fine. The bible specifically says no one knows the exact date the world will end, to shut up all the religious people. The three day black-out is also a hoax, the only planetary objects that could have any substantial affect on the Earth are the moon (because it's so close, but that only deals with tide) and the sun (because it's so large, but it could only cause a solar storm, which isn't supposed to happen until next year and wouldn't seem to have any substantial effect). Any other scientific things such as a magnetic reversal or whatever only happen so many years apart from each other, and I can say with 100% certainty we're far away from any due dates. There's also a Planet X/Nirimu thing going around says some planet 4x the size of Earth will crash into us, but if that were happening, we would've seen it by now.

The only danger we're really in is if a super-eruption occurs at Yellow Stone Park, which is very unlikely as well, but it has a higher chance of happening than any of the things I listed above.

Conclusion: December 22nd exists.

(Oh and December 21 on the Mayan calendar is like December 31 on our's, just saying.)
