Military time converter

How military time works

Military time is the 24-hour clock written as four digits with no colon, from 0000 (midnight) to 2359. The first two digits are the hour and the last two are the minutes. The minutes never change in a conversion; only the hour does.

Military to 12-hour

From 0000 to 0059 the hour is 12 AM. From 0100 to 1159 keep the hour and add AM. From 1200 to 1259 it is 12 PM. From 1300 to 2359 subtract 12 and add PM, so 1430 is 2:30 PM.

12-hour to military

For PM times add 12 to the hour, except 12 PM, which stays 12. For AM times keep the hour, except 12 AM, which becomes 00. So 12:15 AM is 0015 and 12:15 PM is 1215.

Midnight and noon

12:00 AM is midnight, written 0000, at the start of a day. 12:00 PM is noon, 1200. You may see 2400 used for the end of a day, as in "open 0600 to 2400". This converter reads 2400 as midnight and shows it as 0000.

What you can type

1430, 14:30, 2:30 pm and 2pm all work. A time with no am or pm is read as 24-hour, so 2:30 alone means 0230. In speech, 0800 is "zero eight hundred" and 1430 is "fourteen thirty", often followed by "hours".

Time zones

Military messages often add a letter for the zone, such as Z ("Zulu") for UTC. This page changes the format only and never the zone.
