BCE and CE are Common Era, not Christian Era.
They are?????
.. and popularized by Jehovah Winesses.
"The only difference between "BC/AD" and "BCE/CE" is that the term Common Era does not use the religious titles for Jesus ("Lord" and "Christ") that are explicit in "Anno Domini" and "Before Christ". Originating among Christians at least as early as 1617 (at first in Latin),[7] Common Era notation has been adopted by many non-Christians, and also by some Christians wanting to be sensitive to non-Christians.[8] The use of BCE and CE has been criticized by some who favor the BC/AD system as being "the result of secularization" and "political correctness".[9]"
Sorry ... some of us have a memory.
Folks were using the term "Christian Era" in the 1970s and 1980s ... before dreaming up the meaningless term "Common Era"
What's "Common" about it? The term is nonsense
Of course, it's all a fig leaf.
I can understand folks who aren't Christian not wanting to say "Year of Our Lord" (Anno Domini), but pretending that the reference event is anything other than the birth of Jesus of Nazareth is silly. And revisionist. We might well call folks who do that "Nativity Deniers".
