B.C.E. and C.E.

The Christian origin of the designation of years as "B.C." (Before Christ) and "A.D." (Anno Domini, Latin for "in the year of the Lord") has led some people to favor a less culturally specific designation. "C.E." stands for "the Common Era," and "B.C.E." for "Before the Common Era." In practice, the terms are perfect synonyms for "B.C." and "A.D."
