the Mayans made calenders, i did hear they found another one, but you know there is more than two Mayan calenders in the world. the one everyone was sourcing was just one that ended in 2012. some end much sooner, it just comes down to how much room they had on the disk.
i hope you didn't hold this dooms day in high regards. people have predicted the end for centuries, and will continue long after. i don't know what peoples fascination with it is, but it needs to stop, too many panicie people already without the end of days nonsense.
