How Do You Convert 12-Hour AM/PM Time to 24-Hour Military Time?

To convert 12-hour AM/PM time to 24-hour military time, keep AM morning hours as four digits with a leading zero (e.g. 8:30 AM = 0830), change 12:00 AM midnight to 0000, and for afternoon/evening PM hours (1:00 PM to 11:59 PM), add 12 to the hour value (e.g. 7:45 PM = 7 + 12 = 1945).

What Is the International ISO 8601 Standard for 24-Hour Time?

Under international standard ISO 8601, time is represented in a 24-hour format from 00:00:00 to 23:59:59. Military time removes colons (e.g. 1730) while maintaining four fixed digits for standardized communication.

What Is the Mathematical Formula for Military Time Conversion?

Conversion follows The 24-Hour Offset Protocol:

If Time is 12:XX AM: Military Hour = 00
If Time is 1:XX AM to 11:XX AM: Military Hour = Standard Hour (with leading zero)
If Time is 12:XX PM: Military Hour = 12
If Time is 1:XX PM to 11:XX PM: Military Hour = Standard Hour + 12
Military Time String = Military Hour + Minutes (e.g. 0930 or 2145)

Worked Example: How Do You Convert 6:15 PM and 11:45 PM to Military Time?

Consider two evening flight departure timestamps:

Step 1 โ€“ Convert 6:15 PM

Since it is PM (past noon), add 12 to the hour: 6 + 12 = 18. Append minutes: 1815 hours.

Step 2 โ€“ Convert 11:45 PM

Add 12 to the hour: 11 + 12 = 23. Append minutes: 2345 hours.

Step 3 โ€“ Convert 12:30 AM Midnight Shift

Midnight hour becomes 00: 0030 hours.

Why Is Military Time Essential for Overnight Shift Calculations?

Military time simplifies elapsed duration math by avoiding AM/PM ambiguities. For overnight timesheets, calculate hours with our Night Shift Hours Calculator or convert minutes with the Time to Decimal Converter.

How do you convert military time back to regular 12-hour AM/PM? โ–พ
