Military time, also known as the 24-hour clock, is a timekeeping system used by armed forces and other organizations worldwide. It offers a clear and unambiguous way to express time without the need for AM or PM labels. Reading military time is straightforward once you understand its basic principles.
The 24-hour clock starts at midnight (0000 hours) and continues through the day until 2359 hours. For times between 0000 and 0959, simply read the four digits as they appear. From 1000 to 2359, subtract 12 from the first two digits to convert to standard time. This system eliminates confusion and ensures precise communication, especially in critical situations where timing is crucial.
Learning to read military time can be useful for civilians too. Many countries use the 24-hour clock in daily life, and it’s common in industries like aviation, healthcare, and public transportation. By mastering this skill, you’ll be better prepared to interpret schedules and timetables in various settings.

Understanding the 24-Hour Clock
The 24-hour clock is the standard timekeeping system used by the military and many countries worldwide. It eliminates confusion between AM and PM times by using a single 24-hour cycle for each day.
Basics of the 24-Hour Clock System
The 24-hour clock starts at midnight (00:00) and counts up to 23:59. Hours run from 00 to 23, while minutes go from 00 to 59. The first 12 hours match standard clock times, just without AM/PM.
After noon, add 12 to the regular time. For example:
- 1:00 PM = 13:00
- 2:00 PM = 14:00
- 10:00 PM = 22:00
This system removes any doubt about whether a time is AM or PM, making it clearer for scheduling and coordination.
Converting Between 12-Hour and 24-Hour Time
To switch from 12-hour to 24-hour time:
For AM times:
- Keep hours the same (except midnight becomes 00:00)
- Add leading zero if needed
For PM times:
- Add 12 to the hour
- Drop AM/PM
Examples:
- 3:30 AM → 03:30
- 2:45 PM → 14:45
To convert back, subtract 12 from hours 13-23. Add AM for 00:00-11:59, PM for 12:00-23:59.
Reading Minutes in Military Time
Minutes in military time work the same as regular time. They range from 00 to 59. The main difference is how they’re spoken.
In military speak, times are often said as a string of four digits:
- 0630 = “zero six thirty” (6:30 AM)
- 1445 = “fourteen forty-five” (2:45 PM)
For exact times, “hours” and “minutes” are used:
- 0615 = “zero six fifteen hours”
- 2300 = “twenty-three hundred hours”
This system keeps time clear and precise in military operations.
How to Read Military Time
Military time uses a 24-hour clock system. It’s simple to learn and can be useful in many situations. This system eliminates confusion between AM and PM times.
Reading the Hours
Military time starts at 0000 (midnight) and goes up to 2359 (11:59 PM). The first two digits show the hour. For times from midnight to noon, just read the hour as is. For example, 0600 is 6:00 AM.
After noon, add 12 to the civilian hour. So 1:00 PM becomes 1300, 2:00 PM is 1400, and so on. This continues until 2359, which is 11:59 PM.
Remember, there’s no 2400 in military time. The day ends at 2359 and starts over at 0000.
Reading the Minutes
The last two digits in military time show the minutes. These work just like regular time. 0015 is 15 minutes past midnight. 1430 is 30 minutes past 2:00 PM.
Minutes are always shown, even if they’re zero. So 9:00 AM is written as 0900, not just 09.
Combining Hours and Minutes
To read full military times, put the hours and minutes together. Here are some examples:
- 0745: 7:45 AM
- 1200: 12:00 PM (noon)
- 1515: 3:15 PM
- 2330: 11:30 PM
Practice is key. Try converting times back and forth. Soon, reading military time will become second nature.
How to Pronounce Military Time
Military time uses a specific pronunciation system. Knowing the rules helps you say times clearly and avoid confusion. Let’s look at how to say military times out loud.
Pronunciation Rules
Military time is read as a four-digit number. For hours 0000 to 0959, say “zero” before the first digit. From 1000 to 2359, say the first two digits as a whole number. Then say “hundred” for the last two digits if they’re zeros. For other minutes, say them as two separate digits.
Examples:
- 0630: “Zero six thirty”
- 1200: “Twelve hundred”
- 2145: “Twenty-one forty-five”
This system makes times easy to understand in noisy or urgent situations.
Pronouncing Times with Minutes
For times with minutes, say the hour first, then the minutes. Don’t use “o’clock” or “hours.”
Examples:
- 0105: “Zero one zero five”
- 1315: “Thirteen fifteen”
- 2230: “Twenty-two thirty”
In casual settings, you might hear people say “oh” instead of “zero” for the first hour digit. But in formal military contexts, always use “zero.”
Special Pronunciations
Some times have special names in military jargon:
- 0000: “Midnight” or “Zero hundred hours”
- 1200: “Noon” or “Twelve hundred hours”
For date-time groups, pronounce each number separately:
- 082300Z OCT 24: “Zero eight two three zero zero Zulu October two four”
The letter “Z” stands for “Zulu” and means UTC (Coordinated Universal Time).
How to Write Military Time
Writing military time is straightforward once you understand the basic format. It uses a 24-hour clock system that eliminates the need for AM and PM designations.
Format of Military Time
Military time is written as a four-digit number without a colon. The first two digits represent the hour, and the last two represent the minutes. Hours range from 00 to 23, while minutes go from 00 to 59.
For example, 3:30 PM in standard time is written as 1530 in military time. 9:45 AM becomes 0945.
Leading zeros are important. For times before 10:00 AM, add a zero at the start. 7:15 AM is written as 0715.
Writing Hours and Minutes
To write hours in military time, simply use the number corresponding to the hour of the day. For 1:00 PM to 11:59 PM, add 12 to the standard time hour.
1:00 PM = 13:00
6:00 PM = 18:00
11:00 PM = 23:00
Minutes are written the same as in standard time. If the number of minutes is less than 10, add a leading zero.
2:05 PM = 1405
11:30 AM = 1130
Special Cases
Midnight is written as 0000 in military time. This represents the start of a new day.
Noon is written as 1200. It’s the middle of the day and the point where the hour count goes beyond 12.
For 1:00 AM to 11:59 AM, the military time matches the standard time, just with four digits and no colon.
8:00 AM = 0800
11:59 AM = 1159
Practice Examples
Try these exercises to get better at reading and saying military time. They will help you convert between 12-hour and 24-hour formats quickly.
Sample Conversions
Convert these standard times to military time:
- 1:30 PM = 1330
- 3:45 AM = 0345
- 11:15 PM = 2315
Now try the reverse. Change these military times to standard format:
- 1415 = 2:15 PM
- 0830 = 8:30 AM
- 2200 = 10:00 PM
Keep practicing until you can do conversions easily in your head. This skill comes in handy for many jobs and situations.
Pronunciation Practice
Say these military times out loud:
- 0630: “zero six thirty”
- 1445: “fourteen forty-five”
- 2100: “twenty-one hundred”
Remember to use “hundred” for times ending in 00. For other times, say each number separately.
Try saying these aloud:
- 0915: “zero nine fifteen”
- 1330: “thirteen thirty”
- 2359: “twenty-three fifty-nine”
Regular practice will make pronouncing military time feel natural. This clear way of stating times helps avoid confusion in many fields.
Tips and Tricks
Learning to read military time can be made easier with a few simple techniques. These tips will help you quickly convert times and avoid common errors.
Memorization Techniques
Start by memorizing the key hours: 1300 is 1 PM, 1400 is 2 PM, and so on. Practice converting times regularly to build muscle memory.
Create mental associations between military and civilian times. For example, picture a clock face with both 12-hour and 24-hour markings.
Use daily activities as reminders. Link 1500 to the end of a school day or 2000 to your favorite TV show’s start time.
Common Mistakes to Avoid
Don’t forget to subtract 12 from hours after noon. 1800 is not 18 PM, it’s 6 PM.
Be careful with midnight and noon. 0000 and 2400 both mean midnight, while 1200 is noon.
Watch out for leading zeros. 0800 is 8 AM, not 8 PM.
Double-check your conversions, especially when it matters for schedules or appointments.
Helpful Mnemonics
Remember “2 PM is 1400” as a starting point. Add or subtract hours from there.
Use “7 PM, take away 12, add 1900” to quickly convert evening times.
Think “13 is 1, 14 is 2” and so on for the tricky afternoon hours.
Visualize a 24-hour clock face to help connect military times to familiar 12-hour times.
