Dating systems: BC and AD, or BCE and CE?

[Epictetus]

One post mentioned a 'cheat sheet' that had to be devised when reading books which use BCE and CE instead of BC and AD......
Really? Is 'BC' so hugely different from 'BCE' as to require a written reminder? Oh dear.

No, the 'cheat sheet' I mentioned was used in regards to the AUC system, which, since it begins with the traditional founding of Rome, is quite a bit different from the BC/AD or BCE/CE system.
