As *yabob said, they don’t start counting from the year of the presumed birth of Christ but from some other reference year.

Echoing r-k’s sentiments… It’s not OK to bash a whole country out of sheer ignorance.

Well, no, they count the present era from the birth of Christ, they just believe that Christ was born in what we call 7 AD.

From here:

How these figures were arrived at is not stated in the sites I checked.

Thanks for the correct info, but then it looks like their base year is really their presumed date of creation.
