Hours per day

Twenty-four is the cardinal number between twenty-three and twenty-five.

It divides evenly by many numbers—1, 2, 3, 4, 6, 8, 12—making it useful for organizing time and commerce: twenty-four hours in a day, two dozen eggs.

Open twenty-four hours means around the clock.

Twenty-four seven (24/7) means all the time, without interruption.
