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.
1800 hours or eightteen hundred hours is 18:00/6 pm.
It is called "zero eight hundred" hours, and it is 8:00 a.m.
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..

If the time is below 12, eg, 1100 hours, you do not need to convert, just add AM - 1100 hours is 11:00 AM If the time is above 12, you need to subtract 12 and add PM - 2100 hours > (21-12=9) = 9:00 PM.
Melbourne is 21 hours ahead of Honolulu. (ex. Melbourne Time - 6:53am Wednesday/Honolulu Time - 9:53am Tuesday)
The flight time from Bangor, Maine to Melbourne, Australia is:21 hours, 16 minutes
There are 21 hours between 4 p.m. Monday and 1 p.m. Tuesday when measured without changing time zones or adjusting clocks for daylight savings time or other "tricks" to confuse the issue.21 hours twenty-oneas 4 - 1 = 3and 24 - 3 = 21
Add 5 hours to EST (Easter Standard Time [North America]) to get GMT. 21:30 EST is 02:30GMT the next day.
XXI is the Roman Numeral for 21 and would be used on a clock using the 24 hour, or military, time system where 000 (or zero hundred) hours is midnight, 1200 (twelve hundred) hours is 12:00 noon, and 2400 (twenty four hundred) hours is midnight again. This system avoids confusion as to which time of day is being referred to...which could be catastrophic in a military situation. 21 or XXI on the clock would refer to 2100 hours which is 9:00PM by conventional time.
21 00 in military time is 9:00

21:15 in military time is the same as 9:15pm in traditional time. To convert from military time, the hours up to 12 are the same as normal time, they are just all AM times. For anything above 12, subtract 12, but then count it as a PM time.
