When I started university studies in the late 80’s I first encountered the use of BCE/CE (before common era and common era) instead of BC/AD (before Christ and anno domini/year of our Lord).
Recently there was a bit of a kerfuffle about the changing to BCE/CE in the proposed national curriculum for schools.
Anyway, the situation keeps arising in other places.
Lee Shelton at Lemon Harangue Pie observed that the BBC is going through the same process.
He made the helpful graphic below to demonstrate how the change still leaves a most conspicuous point in the middle.
