How many hours between 11pm and 12:30am?

Answer

The difference between 11pm and 12:30am is
1 Hour 30 Minutes

= 90 Minutes · 1.5 decimal hours

11:00 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: 1 h 30 min − 30 min = 1 h paid

day 1
next day
11:00 PM — start 12:30 AM — end, next day
(24:00 − 11:00 PM) + 12:30 AM = 1 h + 30 min = 1 h 30 min = 1.5 h
