How many hours difference is it from 230 AM to 2 AM the next day?

Answer 1

It is 23.5 hours (23 hours thirty minutes). From 2:30 AM one day to the next would be 24 hours.

You can also do this using "military" time if you make each day 2400 hours, express 0200 the next day as the sum, and change the sum into hours and minutes before subtracting (this is the way computer programs do it, e.g. for military flight plan times).

02:00 + 24:00 = 46:00 = 45:60

45:60 - 02:30 = 23:30

Answer 2

23.5 hours
