How many hours between 9pm and 12am?

Answer

The difference between 9pm and 12am is
3 Hours

= 180 Minutes · 3 decimal hours

9:00 PM → 12:00 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.

12 AM is midnight (00:00), 12 PM is noon (12:00).

With a 30-min unpaid break: 3 h − 30 min = 2 h 30 min paid

day 1
next day
9:00 PM — start 12:00 AM — end, next day
(24:00 − 9:00 PM) + 12:00 AM = 3 h + 0 min = 3 hours
