We use a lot more acronyms these days, generally. The better ones can be guessed from context. I personally don't mind the BC/AD, for iron age and later. It's actually convenient that year 0 corresponds roughly to the beginning of Rome's height.
OK, I'd never it before (had to google it).
AD/BC does the job ok for classical history and onwards. Now that "history" is extending back before the bronze age and even to these really early dates...we obviously need a new stamp.
Why is including values of our time bad, while honouring some 2018ya lord good?
I didn't say that was bad, I just figured if you wanted to say 15k years ago you could say 15k years ago instead of making up another acronym, ago isn't a long word. Also I don't necessarily think you have to date from the supposed birthdate of the Jesus Christ. But since we have, why not leave it as is? Why are we being subjected to CE and BCE? It would be quite a message-laden decision if some institutions had a policy of NOT referring to our numbers as Arabic numerals, for instance.
Edit: OK, you'd need to say years ago but still, is this another part of the dropping the AD and BC tendency?
