The dating system is thought to have originated in the ancient city of Assur, and remained the official dating system in Assyria until the end of the Assyrian Empire in the seventh century BC.
This has got to be the right place to ask this question, as you historians must have to deal with this regularly, i know that Dionysius worked out the date for AD 1 (i know he may have got it wrong ! I've noticed some things that as simple as it are we usually don't consider: far less events than today were known according to its exact date. Augustine's City of God and Christian Doctrine | Christian Classics Ethereal Library "While Herod, therefore, reigned in Judea and Caesar Augustus was emperor at Rome... I suspect that for many centuries historians used the classical date for those times before Jesuchrist.
)but that he was using the date to identify easter for the church around 525 Also that AD came into more common use around year 900,but i read that BC was not officially used until around 1751,this sounds too late to me, and i think i must have got it wrong, Please put me on the right track guys and gals Thanks for the reply Gary and for trying to find something, i had the same trouble finding any dates, so it seems Bede may have been using it around 700, but that doesnt mean it was in common use, and the 1751 date was the first official use of BC in britain .

Since this system was introduced by Christians and isn't particularly controversial (as far as I know) between Christian denominations, you could do worse than to read this article ("General Chronology") in the Catholic Encyclopedia. According to one limmu list, a solar eclipse occurred in the tenth reigning year of the Assyrian king Aššur-dan II, in the month of Sivan (May–June on the Gregorian calendar), by Bur-Sagale.Using the Canon of Kings the tenth year can be dated to 763 BC, and modern astronomy dating has backed the Assyrian eclipse up as June 15, 763 BC.Those who oppose the use of the "common era" designation also seem to feel that the use of BC/AD is actually stipulated by the Bible or in some way carries biblical authority.There is no biblical authority for BC/AD; it was created over 500 years after the events described in the Christian New Testament and was not accepted usage until after another 500 years had passed.There are many religious calendars in existence, but each is normally in use in one region of the world -- typically by followers of a single religion.
