Quote:This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, AD counting years from the start of this epoch and BC denoting years before the start of the era. There is no year zero in this scheme; thus the year AD 1 immediately follows the year 1 BC. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century.[4][5]
The bold part being more relevant for my purposes.
That’s because the concept of the zero was unknown to the Greeks and Romans, much less the Jews, and was thus inconceivable and anathema to the Christian, until the concept had been around the world a few times and slapped the Catholic Church in the face on both sides in the 13th century.
