Question: what are bce and ad?
Answer: There is no difference in dating, just in the terms. Anno Domini is Latin for "in the year of the Lord" referring to the birth of Jesus Christ. ... B.C. means "before Christ" and B.C.E. stands for "Before the Common Era". Therefore, 1403 A.D. and 1403 C.E. are the same date as are 4000B.
