How many hours between 10pm and 9am?

Answer

The difference between 10pm and 9am is
11 Hours

= 660 Minutes · 11 decimal hours

10:00 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: 11 h − 30 min = 10 h 30 min paid

day 1
next day
10:00 PM — start 9:00 AM — end, next day
(24:00 − 10:00 PM) + 9:00 AM = 2 h + 9 h = 11 hours
