Uh-uh. The first common use of A.D. was from a monk in 532 A.D. It is not a date set in stone, or some astrological sequence. The terminology is strictly a human construct, and in case you haven't noticed, not all humans are Christians. Jews have their own calendar, as do other cultures. We need a common starting place, but the whole Jesus story is at best just a myth, there is no accuracy about when he was born, or when he died, or even if he actually lived. So to put a religious aspect to a common calendar is just hubris.
