Wow++.  I didn't know this one.

At least there was some time ahead to prepare for the switch from "=E5=B9=B3
=E6=88=90" to "=E4=BB=A4=E5=92=8C".  Things were much "funnier" when the er=

=66rom "=E6=98=AD=E5=92=8C" to "=E5=B9=B3=E6=88=90", as the sudden death of=
 the emperor has required
Japan to switch to a new calendar very suddenly back in the day..
I've heard this was quite a mess for folks in IT back then, especially
