Military time converter

Military time is the 24-hour clock written without a colon: 1430 instead of 2:30 PM. The day runs from 0000 (midnight) to 2359, so there is no AM or PM. It is called military time in the United States, where the 12-hour clock is normal; most of the world uses the 24-hour clock every day.

From 1:00 AM to 12:59 PM, write the hour with two digits and drop the colon: 9:30 AM is 0930, and 12:15 PM is 1215. From 1:00 PM to 11:59 PM, add 12 to the hour: 2:30 PM is 1430. From midnight to 12:59 AM the hour is 00: 12:45 AM is 0045.

If the hour is 13 or more, subtract 12 and add PM: 1745 is 5:45 PM. 1200 to 1259 are PM as they are, 0100 to 1159 are AM, and 0000 to 0059 are 12 AM: 0030 is 12:30 AM.

Both are used. 0000 is the start of a day and 2400 its end, so 2400 on Monday is the same moment as 0000 on Tuesday. Schedules usually use 0000, or 2359 to avoid the question.

Say the hour and the minutes as two numbers, with zero for a leading 0: 0905 is “zero nine zero five” and 1430 is “fourteen thirty”. Full hours end in hundred: 0900 is “zero nine hundred” and 2000 is “twenty hundred”. The word hours is often added: “fourteen hundred hours”.

Yes, the hours are the same. Military time is written without a colon (1430, not 14:30) and often with a time zone letter: 1430Z is 14:30 UTC.
