Working

  1. 2:30 PM: the hour is 2 and it is PM.
  2. PM hours from 1 to 11 get 12 added: 2 + 12 = 14.
  3. Write the hour and the minutes together with no colon: 14 + 30 = 1430.
  4. Say it: “fourteen thirty”.

How to use the military time converter

Type a regular clock time in the first box and choose AM or PM, or type a military time in the second box — the other box, the result and the working update as you type. You can add seconds (9:05:30 or 090530), type 12-hour times with “am” or “pm” in the text, and add a military time zone letter such as 1430Z. Invalid times such as 2460 or 13:00 PM get an explanation instead of a wrong answer. The page address keeps the time, so you can share it.

How to convert to and from military time

Military time counts the hours from midnight, 00 to 23, and writes hours and minutes as four digits with no colon.

12-hour timeMilitary timeRule
12:00 AM – 12:59 AM0000 – 0059The midnight hour: 12 becomes 00
1:00 AM – 11:59 AM0100 – 1159Same hour, with a leading zero below 10
12:00 PM – 12:59 PM1200 – 1259The noon hour stays 12
1:00 PM – 11:59 PM1300 – 2359Add 12 to the hour
PM (1–11): military hour = hour + 12 12 AM: military hour = 00 military → standard: hours 13–23 − 12 = PM hour; 00 = 12 AM; 12 = 12 PM

The minutes never change — only the hour does.

Worked examples

  • 2:30 PM to military: it is PM and the hour is 2, so 2 + 12 = 14. Write it with the minutes and no colon: 1430, said “fourteen thirty”. This is the example already in the converter.
  • 1905 to standard: 19 is more than 12, so 19 − 12 = 7 and it is PM: 7:05 PM. It is said “nineteen zero five”.
  • 0045 to standard: hour 00 is the hour after midnight, written 12 on a 12-hour clock: 12:45 AM.
  • 9:15 AM to military: AM hours stay the same but need a leading zero: 0915, “zero nine fifteen”.

How to say military time

  • On the hour, say “hundred”: 0600 is “zero six hundred”, 1400 is “fourteen hundred” and 0000 is “zero hundred”. “Hours” is commonly added: “fourteen hundred hours”.
  • Otherwise, read two pairs of digits: 1430 is “fourteen thirty”, 2115 is “twenty-one fifteen”.
  • Say the zeros: 0630 is “zero six thirty” and 1405 is “fourteen zero five”. In everyday speech many people say “oh” — “oh six thirty”.
  • Never add AM or PM. “1430 PM” is redundant; the 24-hour clock already tells morning from afternoon.

Military time vs 24-hour time

In the United States “military time” is the everyday name for the 24-hour clock, but strictly they differ in how the time is written, not in the clock itself:

  • Colon. The international standard for dates and times, ISO 8601, writes the time of day as hours, minutes and seconds with colons (14:30 or 14:30:15); military style normally drops the colon (1430).
  • Always four digits. Military time keeps the leading zero (0630). Everyday 24-hour notation in many countries writes 6:30 as well as 06:30.
  • Midnight. 24-hour schedules sometimes use 24:00 for the end of a day, as in “open 09:00–24:00”. Military usage writes midnight as 0000 almost always, which is why this converter shows 2400 only when you type it.
  • Time zone letters. Military times often carry a letter for the time zone, spoken with the phonetic alphabet: Z (Zulu) is UTC and J (Juliett) means local time. Continental US offsets are Q (UTC−4, Eastern daylight time), R (UTC−5, Eastern standard), S (UTC−6), T (UTC−7) and U (UTC−8, Pacific standard). The letters stand for fixed offsets, so Eastern Time is R in winter and Q in summer.

Common mistakes

  • 12 AM and 12 PM. 12:30 AM is 0030, not 1230. 12:30 PM is 1230, not 2430.
  • Treating minutes as decimals. 1430 is 14.5 hours after midnight, not 14.3. To add or subtract times, use the time calculator.
  • Mixing up time zones. A “1400Z” briefing is 2 PM UTC — 10 AM in New York in summer. The time zone converter handles daylight saving time for you.

Frequently asked questions

What time is 1500 in military time?

1500 is 3:00 PM. For any military time from 1300 to 2359, subtract 12 from the first two digits and add PM: 15 − 12 = 3, so 1500 is 3:00 PM, 1745 is 5:45 PM and 2200 is 10:00 PM.

Is midnight 0000 or 2400 in military time?

Both describe the same moment. 0000 is midnight at the start of a day and is what most schedules, logs and computer systems use. 2400 is sometimes used to mark the end of a day — “Monday 2400” is the same instant as “Tuesday 0000”. There is no 2401: the minute after 2359 is 0000.

How do you say 0800 in military time?

“Zero eight hundred” — often followed by “hours”. Times on the hour are said as hundreds (1400 is “fourteen hundred hours”); other times are read as two pairs of digits, so 0630 is “zero six thirty” and 1405 is “fourteen zero five”. In casual speech many people say “oh” instead of “zero”.

What is the difference between military time and 24-hour time?

They use the same clock — hours 00 to 23 from midnight. The difference is how it is written and used: 24-hour notation normally has a colon (14:30), while military time is written as four digits with no colon (1430), is often followed by “hours”, and may carry a time zone letter such as Z for UTC (1430Z).

Is 12 PM noon or midnight?

12 PM is noon (1200) and 12 AM is midnight (0000). The labels trip people up because noon is neither before nor after midday. The 24-hour clock avoids the problem entirely: noon is 1200 and midnight is 0000.

How do I turn military time into decimal hours?

Keep the hours and divide the minutes by 60: 1445 is 14 + 45 ÷ 60 = 14.75 hours after midnight. For hours worked between two clock times, use the hours calculator, which does the subtraction and the decimal conversion together.
