The Anno Domini system is indeed widely accepted as counting 1 BC then AD 1. It is not universally accepted that the first year of the first century was AD 1. Since there is no treaty and no law that has been passed by virtually all countries, it is just a matter of popular usage, and the parties observed on New Year's Eve in 2000 and 2001 suggests popular usage favors the first years of centuries being those ending in "00". Extrapolated backward, that would make 1 BC the first year of the first century.

The "Anno Domini" system is widely accepted as counting 1 BC than 1 AD and not having a zero. It does not
matter what Lil' Dennis intended--- since he did not date things--- but what matters is how the system has been
used by the Churches over the past 1000+ years.
