No. Traditional military-time is written without a time separator.
Traditional military-time is written without a time separator. The standard military format uses four digits, with the first two representing the hour and the last two representing the minutes.
For example:
| Military-Time | Standard-Time |
|---|---|
| 0800 | 8:00 AM |
| 0930 | 9:30 AM |
| 1200 | 12:00 PM |
| 1430 | 2:30 PM |
| 1800 | 6:00 PM |
| 2145 | 9:45 PM |
So if you need to write 2:30 PM in military-time, the correct military-style format is:
not 14:30
U.S. Navy correspondence guidance specifically states that military-time should be expressed in four digits and that a time separator should not be used between the hour and minutes.
If you simply need the correct conversion, you can skip the manual calculation and use the Calculator Online Pro Military-Time Converter. It converts standard time into military format instantly.
Military-Time Uses Four Digits — Not a Colon
The easiest rule is:
For example, 1430 can be separated mentally into:
Together, 1430 means 2:30 PM. You do not write it as 14:30 when following the traditional military-time notation.
The official Navy correspondence manual gives the same format, with examples such as 0630 for 6:30 AM and 1545 for 3:45 PM.
Military-Time vs. 24-Hour Time: 1430 or 14:30?
This is the main reason people search for “Is Military-Time Written With a Colon?” You may see the same time written in three different ways:
| Time Format | Example |
|---|---|
| Military-time | 1430 |
| 24-hour clock | 14:30 |
| Standard time | 2:30 PM |
All three represent the same moment. The important difference is the written convention.
Calculator Online Pro’s current converter likewise presents military-time as four-digit values such as 0000, 0800, 1200, 1300, 1830, and 2359.
Does Military-Time Have a Colon Between Hours and Minutes?
No. The hour and minutes are written together.
| Standard-Time | Military-Time |
|---|---|
| 7:15 AM | 0715 |
| 11:30 AM | 1130 |
| 1:45 PM | 1345 |
| 4:20 PM | 1620 |
| 8:30 PM | 2030 |
| 11:45 PM | 2345 |
Notice that none of the military-time versions contain a colon. The pattern is simple:
Military: 1620
The first two digits are the hour, and the final two digits are the minutes.
Why Does 24-Hour Time Sometimes Have a Colon?
Because 24-hour clock notation and traditional military notation are not always written identically.
A digital clock, computer system, travel schedule, or international timetable may display:
while a military-style document may display:
The actual time is identical. This is why searching for military-time conversions can sometimes produce both versions. The colon is a formatting difference, not a different time.
How to Write Military-Time Correctly
When you need to enter or record military-time, follow these practical rules.
Use Four Digits
Morning times need a leading zero.
not 800
Do Not Add a Colon
When military notation is specifically required, write:
not 14:30
Do Not Add AM or PM
not 1830 PM
The 24-hour value already identifies the part of the day.
Keep Minutes as Two Digits
For 5 minutes past an hour:
not 145
This keeps the military-time format consistent.
Military-Time Colon Examples

Here are common conversions that make the formatting difference easy to see:
| Standard-Time | Military-Time | 24-Hour Clock |
|---|---|---|
| 6:00 AM | 0600 | 06:00 |
| 7:30 AM | 0730 | 07:30 |
| 9:45 AM | 0945 | 09:45 |
| 12:00 PM | 1200 | 12:00 |
| 1:15 PM | 1315 | 13:15 |
| 2:30 PM | 1430 | 14:30 |
| 4:45 PM | 1645 | 16:45 |
| 6:00 PM | 1800 | 18:00 |
| 9:30 PM | 2130 | 21:30 |
| 11:59 PM | 2359 | 23:59 |
The military-time column has no colon. The 24-hour-clock column uses a colon. That is the distinction to remember.
Is 14:30 Military-Time?
14:30 represents the same time as military-time 1430, but the colon-based version is generally described as 24-hour clock notation.
If you are specifically asked to provide the time in traditional military format, enter 1430. If the requested format is a standard 24-hour clock display, you may see 14:30.
This distinction is especially useful when completing forms, reading schedules, converting timestamps, or entering time into systems that expect a specific format.
Is 0800 the Same as 08:00?
Yes. Both represent 8:00 AM, but they use different formatting.
08:00 → colon-based 24-hour format
This is one of the simplest examples to remember. Likewise:
Calculator Online Pro already uses four-digit military values such as 0800 and 1800 in its military-time conversion resources.
Does Military-Time Use a Colon for Midnight?
No. When using the traditional military-style four-digit format, midnight is commonly represented as 0000 rather than 00:00.
The next minute would be 0001, and 0030 is 12:30 AM. This follows the same four-digit, no-colon pattern. Military references show the early-day sequence using values such as 0000, 0001, 0015, 0030, and 0045.
Does Military-Time Use a Colon at Noon?
No. In traditional military notation, noon is:
not 12:00
This is another useful value to memorize because it sits directly in the middle of the 24-hour sequence.
Common Mistakes With Military-Time
Writing 14:30 Instead of 1430
If the requested format is traditional military-time:
✅ 1430
Forgetting the Leading Zero
For morning times:
✅ 0730
Adding PM
✅ 1800
Confusing 1200 and 2400
1200 represents noon. 0000 is commonly used for the start of a new day.
Calculator Online Pro’s converter uses 0000 for midnight and 1200 for noon in its reference chart.
Reading 1400 as 4:00 PM
This is incorrect. 1400 = 2:00 PM. For PM times from 1:00 through 11:00, subtract 12 from the military hour:
Therefore:
The Fastest Way to Check Military-Time Formatting
If you are unsure whether you have written a military-time correctly, check three things:
So the correct structure is:

This simple check eliminates most formatting mistakes.
