How many hours between 1pm and 9am?

Answer

The difference between 1pm and 9am is
20 Hours

= 1,200 Minutes · 20 decimal hours

1:00 PM → 9:00 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: 20 h − 30 min = 19 h 30 min paid

day 1
next day
1:00 PM — start 9:00 AM — end, next day
(24:00 − 1:00 PM) + 9:00 AM = 11 h + 9 h = 20 hours
