1400 is the military and European version of 2:00 p.m.. The military and Europe operate on a 24-hour clock, where noon-onward is expressed as 1200-1300-1400, etc. '1400' is US Marine Corp phrasing, whereas the Army and Air Force would say '1400 hours.'
1400 hours is 2pm
The time is 4:48 PM in normal time.
1800 hours or eightteen hundred hours is 18:00/6 pm.
If you are saying it in military time you would say, "fourteen hundred hours" but if you were saying it civilian language you would say two o'clock pm.
0600 is 6am 1400 is 2pm = 8 hours
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.
Military time is the 24 hour clock. It was created to avoid any confusion between similar sounding times such as 2:00am and 2:00pm. If this was sent over a radio with bad reception for instance! This would be 0200 hours and 1400 hours in military time.
Military time uses a 24 hour clock with no repeated times. The hours are numbered 0100 through 2400, so for the first 12 hours of any day, military time will be the same as a conventional 12 hour clock. However, after 1200 (12:00PM) military time keeps counting up. 1300 (1:00PM), 1400 (2:00PM) and so on. So in this case 1800 would be 18 hours into the day, or 6:00PM.
