Military time is very similar to 24 hour time.
There are 2 differences between the military time setting and the 24 hour time setting. Military time uses a leading zero and doesn’t have a colon, while 24 hour time uses a colon but not a leading zero. So 8 o’clock am is shown as 0800 in military and 8:00 in 24 hour time. 8 pm would be 2000(military) and 20:00(24 hour).
Knowing these differences will help with deciding which time format will be of most use for specific purposes.
