Ante Christum Natum
From Open Encyclopedia
Ante Christum Natum, usually abbreviated to A.C.N., a.C.n., or ACN, Latin for Before the Birth of Christ, denotes the years before the birth of Jesus Christ. It is hence equivalent to the far more common B.C. (Before Christ) and B.C.E. (Before Common Era).
The phrase Ante Christum Natum is commonly seen as the shorter Ante Christum (Latin for Before Christ), again usually abbreviated to A.C. or AC.
