Difference between 9am and 8pm

How many hours between 9am and 8pm?

Answer

The difference between 9am and 8pm is

11 Hours

= 660 Minutes · 11 decimal hours

9:00 AM → 8:00 PM the same day · by the clock, breaks not subtracted

With a 30-min unpaid break: 11 h − 30 min = 10 h 30 min paid

9:00 AM — start 8:00 PM — end

8:00 PM − 9:00 AM = 11 hours
