I find it incredible that pretty much the entire world counts the years off a mythological hero’s birthday (and CE/BCE is just whitewashing the same).
By now there’s probably just too much traction to try to change it, but when this system first spread, was there significant opposition to it? Did anyone try to implement a global Muslim calendar? A Buddhist one? A geologic one?
And what about today? Do countries that ban religion (China, North Korea, etc.) ever try to use their own system, or at least consider the Christian years a despicable but necessary evil?
