Welcome to the sane world of The UK. We remain bemused that we leave you to your own devices for a measly 250 years and you forget how to write dates...

The AD/BC stuff is interesting. The BCE etc may well be technically more fitting but most of us aren't offended by tradition. The idiots pushing technically correct terminology seem to be the sort who say "I mass 100Kg" as technically you "weigh" 9.81KN.

AD/BC is purely perpetuating a tradition rather than a reality. No problem with that per se. As western religion is falling and dying out, it becomes important to keep at least some quaint heritage aspects of our past. However absurd they seem to rational people.
