Military Time Converter

About the Military Time Converter

The military time converter changes 12 hour AM and PM time into 24 hour military time, and military time back into standard time. For example, 2:30 PM equals 1430 in military time.

The bar at the top shows the current time in military format from your device. The Standard to military tab takes an hour, minute and AM or PM and returns the four digit military time, how it is spoken and the 24 hour clock format. The Military to standard tab takes three or four digits, such as 0730 or 1845, and returns the standard time and the spoken form.

How to Use the Military Time Converter

1. Choose a tab for the direction you need.
2. For standard to military, pick the hour, minute and AM or PM.
3. For military to standard, type the four digits, such as 2105.
4. Read the converted time and the spoken form.

What Is Military Time?

Military time is the 24 hour clock written as four digits without a colon. The day starts at 0000 (midnight) and ends at 2359 (one minute before midnight). The first two digits are the hour, from 00 to 23, and the last two are the minutes, from 00 to 59. There is no AM or PM, so morning and evening can never be confused.

How to Convert Standard Time to Military Time

• AM times: write the hour with a leading zero. 6:15 AM becomes 0615. Exception: 12 AM hours become 00, so 12:45 AM is 0045.
• PM times: add 12 to the hour. 3:40 PM becomes 1540. Exception: 12 PM hours stay 12, so 12:30 PM is 1230.

How to Convert Military Time to Standard Time

1. Hour 00: write 12 and add AM. 0030 is 12:30 AM.
2. Hours 01 to 11: drop the leading zero and add AM. 0745 is 7:45 AM.
3. Hour 12: keep 12 and add PM. 1215 is 12:15 PM.
4. Hours 13 to 23: subtract 12 and add PM. 2110 is 9:10 PM.

How to Say Military Time

• On the hour, say “hundred”: 0600 is “zero six hundred” and 1300 is “thirteen hundred”.
• Otherwise, say the two pairs: 1430 is “fourteen thirty”.
• Leading zeros are spoken: 0905 is “zero nine zero five”.
• Midnight is “zero hundred”.

Adding and Subtracting Military Time

Do not subtract military times as plain numbers. 1430 minus 0945 is not 485. Treat hours and minutes as separate columns and borrow 60 minutes, not 100.

For a span past midnight, add 2400 to the end time first. From 2230 to 0615: 3015 − 2230 = 7 hours 45 minutes. The time duration calculator accepts 24 hour times and does this automatically.

Military Time, 24 Hour Time and Zulu Time

24 hour time is the international standard (ISO 8601), usually written with a colon, such as 14:30. Military time is the same clock without the colon, such as 1430. Zulu time is military shorthand for UTC: 1430Z means 14:30 UTC. Military, aviation and weather services use Zulu time so that everyone refers to the same moment. To convert Zulu time to local time, use the time difference calculator with UTC as one location.
