Military Time Converter

This military time converter tool helps you convert 12-hour AM/PM times to 24-hour military format and convert 24-hour times back to 12-hour format.

Time & Date

Quick answer

24-hour time runs from 00:00 through 23:59.

What this tells you

  • 24-hour time runs from 00:00 through 23:59.
  • 12:00 AM is 00:00 and 12:00 PM is 12:00.
  • Afternoon times add 12 hours in 24-hour conversion.

  2. 2Enter time in the source format.
  3. 3For 12-hour input, select AM or PM.
  4. 4Calculate to get converted time format.

How It Works

Formula

12-hour to 24-hour: If PM and hour < 12, add 12. If AM and hour = 12, use 00. 24-hour to 12-hour: If hour = 0, show 12 AM. If hour < 12, show AM. If hour = 12, show PM. If hour > 12, subtract 12 and show PM.

Military time conversion is a rule-based format change, not an arithmetic estimate. The converter preserves minutes and adjusts only the hour plus AM/PM label based on standard 12-hour and 24-hour mapping rules.

Calculation note: values are processed in the order shown above, using the current input units.
