It can be, but it is normally done to specifically indicate the end of a day.
12 AM or 2400
Presumably by 2400 you mean 24:00 as the time. There is no time 24:00 as a minute after 23:59 would normally be written as 00:00, which would be midnight.
15 hours: 1500 is 3PM; 600 is 6AM 3PM to midnight (2400) is 9 hours; midnight (2400) to 6AM (0600) is 6 hours. 9+6 = 15
Since military time follows universal time (sometimes referred to as civilian time) with some formatting changes, both are correct. According to the 1884 International Conference for the purpose of fixing a prime meridian and a universal day the day is to "be counted from zero to twenty-four hours". This means that 0000 is midnight at the beginning of the day and 2400 is midnight at the end of the day. (ie 2400 04JUN is the same moment as 0000 05JUN) In practice, to avoid confusion, most schedules / logs end at 2359 and begin at 0001. While not in accordance with the standard, you will sometimes see universal time reference end or arrival times as greater than 24:00 (eg open 07:00 to 24:15). You will never see this in military time. The above example would be written as 0700 to 0015.
No. After 2300 hours comes 0000. In 24-hour time, the time always means "hours since midnight". 2400 hours would be 0 hours and 0 minutes since midnight, so that time is 0000 hours.
Midnight is always 00:00 and not 24:00.
1200 is Military jargon for Noon and 2400 hours is actually 12:00 am (midnight)
In the french 24-hour clock, you can technically say "Il est vingt-huit heures." (translation: it is 24 hours i.e. 2400) although people almost always say "Il est minuit." (translation: it is midnight).
Written as a percentage, it is 2400%
2400 hours does not exist. Some outdated miltaries will say "2400" to represent midnight, but in reality it doesn't exist.After 2300 hours (11pm) it resets to 0000 hours, which is 12am.1300 = 1pm1400 = 2pm1500 = 3pm1600 = 4pm1700 = 5pm1800 = 6pm1900 = 7pm2000 = 8pm2100 = 9pm2200 = 10pm2300 = 11pm0000 = 12am
