Everybody is... AD, BC... Any other letters are a bastardization of reality.
You need to believe Jesus is the son of God to be a Christian, believing his life was a historical event worthy of measuring history is politically and religiously neutral.
If English-speaking Christians can keep using “Thursday” (Thor’s Day), then non-Christians using the Gregorian calendar can use “B.C.” and “A.D.” without violating their consciences. Otherwise, they can try to get on with the Islamic calendar (1447 AH), Hebrew Calendar (AM 5786), Buddhist calendar (2569–2569 or 2564–2565 depending on location), Chinese calendar (4719, 4720, 2724, 4725, depending on . . . stuff), Ethiopian calendar (2018), Hindu Calendar (2083 VS), Aldous Huxley calendar (AF 118).
I have no problem with AD and BC, I’m a Christian sort of guy.
How do we refer to the 33 or so years Christ was alive?
WA?
