Question 167240
How many hours are there between 8:30 am today and 3:15am tomorrow?
---------------------
From 0830 to 0830 is 24 hours.
Subtract the hours from 0315 to 0830, which is (830 - 315) 5:15.
24:00 - 5:15 = 18:45, 18 hours, 45 minutes.
-----------------
An easier way is call 0315 tomorrow 2715 (add it to 24 hours), then subtract:
2715
-830
1845
