I am a bit confused: wasn’t the traditional mode of age reckoning mostly unofficial anyway? (I thought official documentation and laws all used the “international” age reckoning anyway.)

I can’t really see people just abandoning it overnight.
https://t.co/obctGJaN3N Also, is it wrong of me to suspect some ulterior motive rooted in kooky magical ideas—some “national astrological shift” or “a redirection of national 기” (as in “氣”)—or something?

Just a hunch…
