How many hours between 9am and 1am?

Answer

The difference between 9am and 1am is
16 Hours

= 960 Minutes · 16 decimal hours

9:00 AM → 1:00 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: 16 h − 30 min = 15 h 30 min paid

day 1
next day
9:00 AM — start 1:00 AM — end, next day
(24:00 − 9:00 AM) + 1:00 AM = 15 h + 1 h = 16 hours
