B.C. and A.D. or B.C.E. and C.E.? The Battle Over History:
"The nonsensical nature of this proposal comes down to this -- there is no way to get around the fact that the hinge year is assumed by tradition to be the year of Christ's birth. One can try to avoid any reference to Christ by using B.C.E. and C.E., but the numbers of the years still tell the story. If advocates of this change are really serious about avoiding all references to Christ, they will have to come up with a whole new numbering system for the years."
