How many hours between 1am and 12pm?

Answer

The difference between 1am and 12pm is

11 Hours

= 660 Minutes · 11 decimal hours

1:00 AM → 12:00 PM the same day · by the clock, breaks not subtracted

12 AM is midnight (00:00), 12 PM is noon (12:00).

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

1:00 AM — start 12:00 PM — end

12:00 PM − 1:00 AM = 11 hours
