About Military Time

Military time uses a 24-hour clock notation system where the day runs from 0000 (12:00 AM) to 2359 (11:59 PM). It is widely used by military organizations, emergency services, hospitals, and in countries that use the 24-hour time format.

How to Read Military Time
  • The first two digits represent the hour (00-23)
  • The last two digits represent minutes (00-59)
  • 0000 (pronounced "zero hundred hours") is midnight
  • 1200 (pronounced "twelve hundred hours") is noon
  • For times from 0100 to 0959, drop the leading zero when pronouncing (e.g., 0730 is pronounced "seven thirty hours")
  • For times from 1000 to 2359, pronounce all digits (e.g., 1545 is pronounced "fifteen forty-five hours")

Conversion Formula

To convert Standard to Military Time:

If PM and hour ≠ 12 → Military Hour = hour + 12

Military Time = Military Hour + Minutes

To convert Military to Standard Time:
