How many hours between 8pm and 12:30am?

Answer

The difference between 8pm and 12:30am is
4 Hours 30 Minutes

= 270 Minutes · 4.5 decimal hours

8:00 PM → 12:30 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.

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

With a 30-min unpaid break: 4 h 30 min − 30 min = 4 h paid

day 1
next day
8:00 PM — start 12:30 AM — end, next day
(24:00 − 8:00 PM) + 12:30 AM = 4 h + 30 min = 4 h 30 min = 4.5 h
