24-hour clock vs military time

A 24-hour clock writes hours from 00 to 23 with a colon, like 13:00 or 07:30. Military time is the same clock without the colon: 1300 and 0730. Both drop AM/PM, which is why hospitals, aviation, and logistics prefer them.

Quick examples

00:00 / 0000 = 12:00 AM (midnight)
12:00 / 1200 = 12:00 PM (noon)
13:00 / 1300 = 1:00 PM
17:45 / 1745 = 5:45 PM
