Just a general explanation of this Time's End.

Mayans never predicted the time's end. It was some religious nutjobs believing that the world would end since their calendar only reaches the Baktun 13th, which is a time measure that lasts about 4,000 years, each Baktun comes with 20 katunes, and each katun comes with 200 tuns. Each tun has 360 days.

Anyway, we start the new Baktun. And today shall be the Tzolkin's 4 Ahau and Haab's 3 Kankin.

It is important to know that the mayans were not exactly religious, but rather a scientific community that made a lot of calculations, star reading and other things. Not to be mistaken with the aztecs, as they were a warrior and religius community. In other words, some religious nutjob used science.
