Military Time Converter

Military time is a timekeeping system based on the full 24 hours of the day.

Unlike the standard 12-hour clock, it never repeats. There's no AM or PM confusion.

It runs from 0000 (midnight) to 2359 (one minute before midnight).

The military, emergency services, aviation, and hospitals use it worldwide for precision and clarity.

Why Use Military Time?

Standard 12-hour time can cause dangerous confusion. Is "6:00" morning or evening?

Military time eliminates that ambiguity entirely. Each moment has one unique number.

1. Used by the US Army, Navy, Air Force, and Marines
2. Standard in hospitals and emergency dispatch centers
3. Required in aviation and international shipping
4. Prevents scheduling errors across time zones

How to Read Military Time?

Military time is expressed as a four-digit number. The first two digits are the hour. The last two are the minutes.

For example, 1430 means 2:30 PM. You read it as "fourteen thirty hours."

Times before 1000 always start with a zero. So 9:05 AM becomes 0905, read as "zero nine zero five."

Quick Reading Rules

• 0000–0059 = Midnight to 12:59 AM
• 0100–1159 = 1:00 AM to 11:59 AM
• 1200–1259 = Noon to 12:59 PM
• 1300–2359 = 1:00 PM to 11:59 PM
• 2400 = End of day (same as 0000)

How to Calculate Military Time by Using Our Tool?

Converting between military and standard time is straightforward once you know the rules.

Standard Time → Military Time

• If it's AM: Remove the colon and add a leading zero if the hour is single-digit. Example: 9:15 AM → 0915
• If it's 12:xx PM: Keep 12 as-is. Example: 12:30 PM → 1230
• If it's PM (not 12): Add 1200 to the hour. Example: 3:45 PM → 3 + 12 = 15 → 1545
• If it's 12:xx AM (midnight): Replace 12 with 00. Example: 12:10 AM → 0010

Military Time → Standard Time

• If the number is 0000–0059: It's 12:xx AM
• If the number is 0100–1159: It's AM. Just add the colon.
• If the number is 1200–1259: It's 12:xx PM
• If the number is 1300–2359: Subtract 1200 to get PM time

Military Time Calculation Formula

The core formulas for conversion are simple arithmetic:

12-Hour to Military Time

• AM hours (except 12 AM): Military = Hour × 100 + Minutes
• 12 AM (midnight): Military = 0 × 100 + Minutes = 00MM
• PM hours (except 12 PM): Military = (Hour + 12) × 100 + Minutes
• 12 PM (noon): Military = 12 × 100 + Minutes = 12MM

Military Time to 12-Hour

• Extract hours: H = floor(Military ÷ 100)
• Extract minutes: M = Military mod 100
• If H = 0: 12:MM AM
• If H < 12: H:MM AM
• If H = 12: 12:MM PM
• If H > 12: (H − 12):MM PM

Conversion Example

Let's walk through a real example step by step.

Example 1: Convert 2:45 PM to Military Time

• It's PM and not 12, so add 12 to the hour: 2 + 12 = 14
• Keep the minutes: 45
• Result: 1445 hours ("Fourteen Forty-Five Hours")

Example 2: Convert 1830 to Standard Time

• Hours = 18, Minutes = 30
• 18 > 12, so subtract 12: 18 − 12 = 6
• It's PM
• Result: 6:30 PM

Example 3: Convert 12:00 AM to Military Time

• Midnight is a special case
• Replace 12 with 00
• Result: 0000 hours ("Zero Hundred Hours")
