@SpaceTurtle224 you're "looking for" and easy answer to a question you can answer yourself easily. Your "question" did not even specify what your looking for.

@Sigmatics Habits can be unlearned over a few generations. Doesn't mean in becomes practical all if a sudden. It's just messy to say "I'll do this tomorrow" when "tomorrow" might mean "before I go to bed".
"See you Monday!"
"Eh, before or after sleep on Monday?"
It's just not viable. It requires us to think differently about what a date is, returning the original issue: different people living at different dates.
@Sigmatics you can have everyone on the same time zone and still have different day/night cycles. It just means you have to get up at 14:00 and go to sleep at 5:00. The big problem with this is that the date-switch happens for everyone at the same time, which means you might have breakfast on Thursday and lunch on Friday. That makes it terribly inconvenient, and therefore probably unviable.
@misophist Nah.
