How many hours between 12pm and 4am?

Answer

The difference between 12pm and 4am is
16 Hours

= 960 Minutes · 16 decimal hours

12:00 PM → 4:00 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: 16 h − 30 min = 15 h 30 min paid

day 1
next day
12:00 PM — start 4:00 AM — end, next day
(24:00 − 12:00 PM) + 4:00 AM = 12 h + 4 h = 16 hours
