@KohakuJSMA Actually, the theory is based on the fact that there will be an alignment of the Sun and the center of galaxy in that day... It doesn't have anything to do with numbers.
I think the world will definately end some day, but I have no idea when. It's certainly an interesting theory, because it's the only end-of-the-world hysteria with at least SOME actual arguments to support it apart from "the millenia is changing" 或者 "a religious guy saw it in a dream". However, I still don't believe it's much likely to be true.
