How many hours between 9pm and 10am?

Answer

The difference between 9pm and 10am is
13 Hours

= 780 Minutes · 13 decimal hours

9:00 PM → 10:00 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: 13 h − 30 min = 12 h 30 min paid

day 1
next day
9:00 PM — start 10:00 AM — end, next day
(24:00 − 9:00 PM) + 10:00 AM = 3 h + 10 h = 13 hours
