How many hours between 3pm and 3am?

Answer

The difference between 3pm and 3am is
12 Hours

= 720 Minutes · 12 decimal hours

3:00 PM → 3:00 AM next day · by the clock, breaks not subtracted

The end is earlier than the start, so it falls on the next day (+24 h). On a night the clocks change, the real span differs by the size of the change.

With a 30-min unpaid break: 12 h − 30 min = 11 h 30 min paid

day 1
next day
3:00 PM — start 3:00 AM — end, next day
(24:00 − 3:00 PM) + 3:00 AM = 9 h + 3 h = 12 hours
