It is commonly thought that BC stands for “before Christ” and AD stands for “after death.” This is only half correct. How could the year 1 B.C. have been “before Christ” and 1 A.D. been “after death”? BC does stand for “before Christ.” AD actually stands for the Latin phrase “anno domini” which means “in the year of our Lord.” The B.C. / A.D. dating system is not taught in the Bible. It actually was not fully implemented and accepted until several centuries after Jesus’ death.
