No one can possibly know what will happen. There is significance in an end of a culture’s calendar, however.
even crazy Wikipedia has debunked it.
There is no ending to the Calendar...
as a matter of fact....

It hasn’t been needed yet though.
Ever thought that calendar maker may have run of stone?
The Mayans had a circular concept of time—they had several of these “last days”—all it means is that change will come that will change everything. Last time this hit was in the 16th Century when Cortez landed in Mexico (that changed a great many things—some good —No more hearts being cut out, and Christian Church—and some bad—slavery and serfdom.) So a change is coming! It might be both good and bad as well. A new invention, contact with space people, a plague, a new world government? World War Three? —It could be many things. BUT it will not be the end of all life on earth.
