clock hour
One twelfth day
A clock hour is a full sixty-minute period, as opposed to an academic hour or other shortened unit.
The term appears in contexts where the distinction matters—professional licensing, continuing education credits, or flight training: The course requires forty clock hours of instruction.
Sometimes called a contact hour.
