Because unless you live underground, are blind, or live so far north or south that the day night cycle loses cohesion it’s literally as easy as “Can I see daylight?” If you really want to fix it round hours out to 20-30 for easier conversion between days and smaller units, 7 day weeks? That’s backwards and hard to convert mentally, make them 10 days. Months are just tied to the lunar cycle we can do better surely. Years are stuck though unless we speed up or slow the Earth’s orbit. While we are at it, one time zone, if everyone is on identical clocks it’ll save so many issues, I don’t want to know when 21:00 is in Hong Kong, I’ll just call at Universal 11:00

Sure, there’s a lot wrong about the way we work with time and date. Months are not even tied to lunar cycles, we have around 13 of them in a year.
But conversion from 12 to 24 hour format is already there and easy to switch to without losing anything. Let’s start going rational.
Or we could just embrace minor cultural differences instead of smoothing humanity out into boring orthodoxy
I’m pretty sure the time ans date format is not what makes a culture special, though.
