Difference between 1am and 7pm

How many hours between 1am and 7pm?

Answer

The difference between 1am and 7pm is

18 Hours

= 1,080 Minutes · 18 decimal hours

1:00 AM → 7:00 PM the same day · by the clock, breaks not subtracted

With a 30-min unpaid break: 18 h − 30 min = 17 h 30 min paid

1:00 AM — start 7:00 PM — end

7:00 PM − 1:00 AM = 18 hours
