Military Time Chart: 0000 to 2300 With Standard Time Equivalents

Written by Om Vaghani · Published October 9, 2026 · 6 min read

1700 in military time is 5:00 PM. The rule for any afternoon or evening time is simple: if the hour is 13 or higher, subtract 12 and add PM. So 1700 becomes 17 - 12 = 5, which is 5:00 PM. Morning times from 0100 to 1159 are the same as standard time, just written with four digits and no AM.

Military time is the 24-hour clock written as four digits with no colon. It is used by armed forces, and the same 24-hour system is widely used in hospitals, aviation, public transport timetables and most countries outside the US. If you want to convert a specific time instantly, use the military time converter.

The quick answer

| Military time | Standard time | |---|---| | 0000 | 12:00 AM (midnight) | | 0600 | 6:00 AM | | 1200 | 12:00 PM (noon) | | 1300 | 1:00 PM | | 1700 | 5:00 PM | | 2000 | 8:00 PM | | 2359 | 11:59 PM |

Conversion rule: for 1300 to 2359, subtract 12 from the hour and add PM. For 0000 to 0059, the hour is 12 AM. For 0100 to 1159, drop the leading zero and add AM. 1200 to 1259 is PM with no change to the hour.

Some people say "oh" instead of "zero" (oh-six hundred) in casual speech. In military and aviation radio procedure, "zero" is preferred because it is harder to mishear.

How to say military time out loud

Military time is read as a four-digit number, usually in two pairs.

• On the hour: say the hour, then "hundred". 1700 is "seventeen hundred". 0900 is "zero nine hundred".
• With minutes: say the hour pair, then the minute pair. 1745 is "seventeen forty-five". 0830 is "zero eight thirty".
• Minutes under 10: say the zero. 1405 is "fourteen zero five".
• Hours: you may hear "hours" added at the end in formal use, as in "seventeen hundred hours".

Midnight: 0000 vs 2400

Both refer to midnight, but they mark opposite ends of the day.

• 0000 is the start of a day. 0000 on 10 March is the first moment of 10 March.
• 2400 is sometimes used for the end of a day. 2400 on 9 March is the same instant as 0000 on 10 March.

In practice, most systems use 0000 and avoid 2400, because 2400 can make it unclear which date is meant. Timetables and digital clocks generally go from 2359 straight to 0000. You may still see 2400 in some schedules and shift rosters to show that a shift ends exactly at midnight. When it matters, write the date as well.

There is no 2401. One minute after midnight is 0001.

How minutes work

Minutes in military time are exactly the same as in standard time. Only the hour changes.

| Military | Standard | |---|---| | 0015 | 12:15 AM | | 0645 | 6:45 AM | | 1130 | 11:30 AM | | 1210 | 12:10 PM | | 1555 | 3:55 PM | | 1725 | 5:25 PM | | 2050 | 8:50 PM | | 2359 | 11:59 PM |

Seconds, when needed, are usually written with colons in 24-hour format (17:25:30), though strict military style rarely uses them.

Converting in your head

Military to standard

1. Look at the first two digits (the hour).
2. 00: change to 12 and add AM.
3. 01 to 11: keep the number (drop any leading zero) and add AM.
4. 12: keep 12 and add PM.
5. 13 to 23: subtract 12 and add PM.
6. Keep the last two digits as the minutes.

Examples: - 0035 = 12:35 AM - 0715 = 7:15 AM - 1200 = 12:00 PM - 1840 = 18 - 12 = 6, so 6:40 PM - 2230 = 22 - 12 = 10, so 10:30 PM

Standard to military

1. AM times: 12 AM becomes 00. Otherwise keep the hour and add a leading zero if it is a single digit.
2. PM times: 12 PM stays 12. Otherwise add 12 to the hour.
3. Remove the colon.

Examples: - 12:20 AM = 0020 - 4:05 AM = 0405 - 12:45 PM = 1245 - 3:30 PM = 3 + 12 = 15, so 1530 - 9:00 PM = 9 + 12 = 21, so 2100

You may come across other mental shortcuts, but the add-12 and subtract-12 rules are the least error-prone. Stick with those.

Where you will see it

• Healthcare: medication times and patient charts commonly use the 24-hour clock so there is no AM/PM confusion.
• Aviation: flight plans use the 24-hour clock, usually in UTC (often called Zulu time).
• Military: orders, logs and radio communication.
• Travel: train and flight timetables in much of the world.
• Shift work: police, fire, security and many factory rosters.

If you deal with several time zones as well, the world clock shows current times around the globe, and the online clock can display your local time in 24-hour format.

Calculating with military time

One nice thing about the 24-hour clock is that working out durations is easier, since you do not need to cross from AM to PM.

Example: a shift from 0645 to 1530. - Think of it as 15 h 30 min - 6 h 45 min. Since 30 minutes is less than 45, borrow an hour: 14 h 90 min - 6 h 45 min. - 14 - 6 = 8 hours, 90 - 45 = 45 minutes. - Shift length: 8 h 45 min

For anything longer or crossing midnight, the time duration calculator or hours calculator is quicker.
