What is the difference between 12 hour clock time and 24 hour clock time?

Answer 1

A twelve hour clock has 1,2,3,4,5,6,7,8,9,10,11,12 and is the standard form time clock. A 24 hour clock has times starting at 1-12, but after it will start with 13 as 1 p.m. all the way to 24 or 00 as 12 midnight.

Answer 2

A 12 hour clock would measure time in 12 hour cycles, when the clock gets to 12am or pm it starts again at 1am or pm.

The 24 hour clock would measure time in 24 hour cycles.
