Explanation in the comments

What about the lengths of days?

An hour is still as long as before so if would still be 24 hours, or 2400 minutes.

That's boring

Well what if a day was 100 hours AND an hour was 100 minutes?

Not 100 hours, something like 15, like how we can have 8 hours sections in 3, we could have 3 sections of 5

Ok ill see what u can do with 15

*what I can do

Each hour of the new time is 1.6 normal hours.
