How many hours between 11pm and 11am?

Answer

The difference between 11pm and 11am is
12 Hours

= 720 Minutes · 12 decimal hours

11:00 PM → 11:00 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
11:00 PM — start 11:00 AM — end, next day
(24:00 − 11:00 PM) + 11:00 AM = 1 h + 11 h = 12 hours
