21:00 is 9 pm. This is because military time runs on a 24-hour clock instead of 12. 1 am is considered the first hour (1:00), 2 am is the second hour (2:00) and so on up to 24 hours. It is often used in the practice of medicine to avoid ambiguity about when events occurred in a patient's history.

0600 military time is 6 a.m. civilian time. Like civilian time, military time starts at midnight, so 0600 and 6 a.m. are the same, except for the slightly different terminology..
