Common era is kinda dumb terminology because it is meant to contrast with the regnal era (year used by commoners vs year of monarchs reign).
Jewish people in Europe used common era as well as current era which I feel makes more sense.
Altogether better is the Czech terminology which uses “of our years” and “before our years”.
I’ve also heard of retconning bc/ad to be “backwards count” and “ascending dates”
That’s around 33 CE.
