I find this change very interesting because I learned to reference these eras as BC and AD.
What does BC and AD stand for? And why were they changed to BCE and CE?
Our calendar was based on the birth of Christ; all years before Christ’s birth have traditionally been designated B.C. (before Christ) and those after his birth as A.D., an abbreviation for the Latin term “Anno Domini” which means “in the year of the Lord.”
Now, scientists and historians have adopted an alternative dating system. They’re referring to B.C. as B.C.E. (before the Common Era), and to A.D. as C.E. (Common Era).
The change was made to mask the Christian basis for the dating system, in a bid to accommodate non-Christians and maintain political correctness.
