What is Military Time?
Military time is a precise way of expressing time using the 24-hour clock system, where the day runs continuously from midnight to midnight without the need for AM or PM designations. It is commonly referred to as the “24-hour clock” in most parts of the world, but in American English, it is specifically called military time due to its widespread use in the U.S. armed forces and allied military operations.
Key Definition and Features
- Military time measures time in 24-hour increments, starting at 00:00 (midnight) and ending at 23:59 (one minute before the next midnight). Sometimes, the end of the day is noted as 24:00.
- It uses four digits to represent time: the first two digits indicate the hour (00–23), and the last two indicate the minutes (00–59). For example:
- 1:00 AM = 0100 (pronounced “zero one hundred” or “oh one hundred”).
- 2:30 PM = 1430 (pronounced “fourteen thirty”).
- 11:59 PM = 2359 (pronounced “twenty-three fifty-nine”).
- Unlike standard 12-hour time (which uses AM/PM and often includes a colon, like 2:30 PM), military time typically omits the colon in strict notation (e.g., 1430 instead of 14:30) for clarity and brevity, especially in written communications, logs, or digital displays.
- Leading zeros are used for hours 1–9 (e.g., 0900 for 9:00 AM) to maintain a consistent four-digit format.
Why It’s Called “Military Time”
The U.S. military (and many allied forces) adopted this format to eliminate any confusion between morning and afternoon hours, which is critical in 24/7 operations like combat, aviation, logistics, and communications. The system ensures unambiguous timing across different time zones, often with added suffixes like “Z” for Zulu (UTC) time in operations.
Military Time vs. Standard 24-Hour Clock
While the terms are often used interchangeably:
- The plain 24-hour clock (common in Europe, Asia, and most of the world) usually includes a colon (e.g., 14:30) and may not always use leading zeros.
- Military time (especially in U.S. contexts) emphasizes the no-colon, four-digit format with leading zeros and phonetic pronunciation (e.g., “thirteen hundred” for 1300).
This format is not exclusive to the military—it’s also standard in healthcare (e.g., hospitals and nursing), emergency services, aviation, railroads, transportation, and scientific fields where precision prevents errors.
In short, military time is simply the 24-hour clock optimized for clarity, reliability, and zero ambiguity in high-stakes environments. It’s the same system used globally for most official schedules, but with a distinct American nickname and notation style.

Notes on the full chart:
- For any time not listed (e.g., 0815), simply match the hour and keep the minutes the same (0815 = 8:15 AM).
- Midnight can be written as 0000 (start of the day) or sometimes 2400 (end of the previous day).
- This format is widely referenced in reliable sources like medical training materials, university documents, and time conversion tools.
For even finer detail (every 15 minutes), many printable PDFs expand this further, but the 30-minute increments above provide a clear, complete, and commonly used full reference. You can copy this table into a document, add colors or formatting, and print it as a handy military time chart printable. If you need a version with every 15 minutes or decimal minute conversions (for payroll/timesheets), let me know!
How Military Time Works?
Military time, also known as the 24-hour clock, is a continuous timekeeping system that divides the day into 24 distinct hours instead of resetting at noon like the standard 12-hour clock (which uses AM/PM). This eliminates any confusion about whether a time is in the morning or afternoon, making it ideal for precise, unambiguous communication in operations that run 24/7.
Core Mechanics of How It Works?
- The day starts at midnight, which is written as 0000 (or sometimes 2400 to mark the end of the previous day).
- It progresses hour by hour up to 2359 (11:59 PM), the last minute before the next midnight.
- After 2359, the clock rolls over to 0000 of the next day.
- There is no AM or PM—each hour of the 24 has its own unique number:
- Morning hours (midnight to just before noon): 0000 to 1159.
- Afternoon and evening hours (noon onward): 1200 to 2359.
- Time is expressed as a four-digit number without a colon in strict military notation:
- The first two digits = hours (00–23).
- The last two digits = minutes (00–59).
- Leading zeros are used for single-digit hours (e.g., 1:00 AM = 0100, not 100).
Key Examples of How It Flows?
- Midnight (start of day) → 0000 (pronounced “zero hundred hours” or “oh hundred”).
- 1:00 AM → 0100 (“zero one hundred” or “oh one hundred”).
- 9:45 AM → 0945 (“zero nine forty-five”).
- Noon → 1200 (“twelve hundred”).
- 1:00 PM → 1300 (“thirteen hundred”).
- 6:30 PM → 1830 (“eighteen thirty”).
- 11:59 PM → 2359 (“twenty-three fifty-nine”).
- End of day / next midnight → 2400 (sometimes used interchangeably with 0000).
Pronunciation Rules (How It’s Spoken)
In military and professional settings, time is read clearly and consistently:
- Full hours often use “hundred hours” (e.g., 1400 = “fourteen hundred hours”).
- For single-digit hours, say “zero” or “oh” (e.g., 0500 = “zero five hundred” or “oh five hundred”).
- Minutes are read as normal numbers (e.g., 1430 = “fourteen thirty”).
- Avoid saying “thousand” — it’s always “hundred” for clarity (e.g., not “fourteen thousand”).
Quick Conversion Logic
- From standard 12-hour to military:
- For AM times (12:00 AM to 11:59 AM): Add a leading zero if needed (e.g., 7:15 AM → 0715). 12:00 AM = 0000.
- Noon = 1200.
- For PM times (1:00 PM to 11:59 PM): Add 12 to the hour (e.g., 4:45 PM → 1645).
- From military to standard:
- If the first two digits are 00–11 → AM time (00 = 12 AM midnight, 01–11 = 1–11 AM).
- If 12 → Noon (12 PM).
- If 13–23 → Subtract 12 and add PM (e.g., 17:00 → 5:00 PM).
Why This System Works So Well?
By running straight through 24 unique hours without repeating numbers or adding AM/PM labels, military time prevents critical mix-ups (e.g., scheduling a briefing at “0800” is unmistakably 8:00 AM, not 8:00 PM). It’s the same foundation as the global 24-hour clock but with specific notation tweaks (no colon, leading zeros, phonetic-style reading) tailored for military precision.
This straightforward, rolling 24-hour structure is why military time is reliable, efficient, and widely adopted beyond just the armed forces—in aviation, emergency services, hospitals, and international coordination. Once you grasp the continuous count from 0000 to 2359, it becomes second nature!
How to Read Military Time? (Simple Guide)
Reading military time is actually very straightforward once you understand the basic rules. Military time uses the 24-hour clock format and is written as a four-digit number (e.g., 1430, 0945, 0000). Here’s a simple, step-by-step guide to reading it correctly every time.
1. Break It Into Two Parts
Every military time has four digits:
- First two digits = the hour (00 to 23)
- Last two digits = the minutes (00 to 59)
Examples:
- 1430 → 14 (hour) + 30 (minutes)
- 0945 → 09 (hour) + 45 (minutes)
- 2359 → 23 (hour) + 59 (minutes)
2. Read the Hour (00–23)
- If the hour is 00 to 11 → it’s morning (AM), except 00 is midnight and 12 is noon.
- If the hour is 12 → it’s noon (12:00 PM).
- If the hour is 13 to 23 → it’s afternoon/evening (PM). To convert to standard time, subtract 12 from the hour.
Quick hour cheat sheet:
- 00 = 12 AM (midnight)
- 01–11 = 1 AM – 11 AM
- 12 = 12 PM (noon)
- 13 = 1 PM
- 14 = 2 PM
- … up to …
- 23 = 11 PM
3. Read the Minutes
The last two digits are just regular minutes — read them exactly as you would in normal time.
Examples:
- 30 = thirty
- 45 = forty-five
- 05 = five
- 00 = hundred (for full hours)
4. How to Say It Out Loud? (Military Style)
In military, aviation, emergency services, and professional settings, time is spoken clearly using these patterns:
- Full hours: “___ hundred hours”
- 0800 = “zero eight hundred” or “oh eight hundred hours”
- 1400 = “fourteen hundred hours”
- With minutes: just say the four digits in pairs
- 1430 = “fourteen thirty”
- 0945 = “zero nine forty-five” or “oh nine forty-five”
- 2359 = “twenty-three fifty-nine”
You don’t say “AM” or “PM” — the hour number itself tells you whether it’s morning or afternoon.
Quick Reading Examples
| Military Time | How to Read It | Standard Time |
|---|---|---|
| 0000 | zero hundred / midnight | 12:00 AM |
| 0630 | zero six thirty | 6:30 AM |
| 0900 | oh nine hundred | 9:00 AM |
| 1200 | twelve hundred | 12:00 PM (noon) |
| 1345 | thirteen forty-five | 1:45 PM |
| 1700 | seventeen hundred | 5:00 PM |
| 2145 | twenty-one forty-five | 9:45 PM |
| 2359 | twenty-three fifty-nine | 11:59 PM |
Fast One-Second Rule for Any Time
- Look at the first two digits (the hour).
- If 00–11 → morning (AM), except 00 = midnight.
- If 12 → noon.
- If 13–23 → afternoon/evening (PM) — subtract 12 to get the regular hour.
- Say the last two digits as normal minutes.
That’s it! Practice with a few times each day (like checking a clock or schedule in military format), and within a week you’ll read it instantly without thinking. It becomes second nature very quickly.
Military Time Format Around the World
The 24-hour format is the world’s most widely used time notation and is standard for schedules, transport, and official use in most countries (e.g., Europe, Asia, Latin America, Africa). In daily speech, many nations (like Germany, France, Indonesia, China, Brazil) prefer 24-hour time, while English-speaking countries like the US commonly use 12-hour (AM/PM) in civilian life but mandate 24-hour/military time in professional, military, aviation, and medical contexts. The military everywhere uses the 24-hour system for unambiguous global coordination.
