How many hours between 11pm and 9am?

Answer

The difference between 11pm and 9am is
10 Hours

= 600 Minutes · 10 decimal hours

11:00 PM → 9:00 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: 10 h − 30 min = 9 h 30 min paid

day 1
next day
11:00 PM — start 9:00 AM — end, next day
(24:00 − 11:00 PM) + 9:00 AM = 1 h + 9 h = 10 hours
