The way to count the years is very differently and as ghaele say it's only ca. 600 years old (our current way).
The Islam cultures count sometimes from the moment on which Mohammed fled to Medina.
The Jews count from the writing of the 10 (don't know this word in english) of Mozes.
And Mayans, well, they count(ed) even more different don't know who, has something to do with the sun.
It's interesting to find out how they counted their years in the past ...
