How many hours between 8:30pm and 8am?

Answer

The difference between 8:30pm and 8am is
11 Hours 30 Minutes

= 690 Minutes · 11.5 decimal hours

8:30 PM → 8:00 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 − 30 min = 11 h paid

day 1
next day
8:30 PM — start 8:00 AM — end, next day
(24:00 − 8:30 PM) + 8:00 AM = 3 h 30 min + 8 h = 11 h 30 min = 11.5 h
