How many hours between 9:30pm and 9:30am?

Answer

The difference between 9:30pm and 9:30am is
12 Hours

= 720 Minutes · 12 decimal hours

9:30 PM → 9:30 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
9:30 PM — start 9:30 AM — end, next day
(24:00 − 9:30 PM) + 9:30 AM = 2 h 30 min + 9 h 30 min = 12 hours
