What Is Military Time?
Military time, also known as the 24-hour clock, is a timekeeping system where the day runs from midnight to midnight and is divided into 24 hours, numbered from 0 to 23. This system is used by military, aviation, healthcare, emergency services, and many countries worldwide.
Unlike the 12-hour clock (AM/PM), military time eliminates confusion between morning and afternoon hours. For example, 3:00 PM becomes 1500 (fifteen hundred hours), and 12:00 AM becomes 0000 (zero hundred hours).
Key Conversion Rules:
12:00 AM = 0000 | 1:00 AM = 0100 | 12:00 PM = 1200 | 1:00 PM = 1300
For PM times (except 12 PM), add 12 to the hour. For AM times (except 12 AM), keep the hour as-is.

- Standard → Military: Convert the 12-hour time to 24-hour format. For 12:00 AM, use 00:00. For 1:00 AM to 11:59 AM, keep the hour as-is. For 12:00 PM, use 12:00. For 1:00 PM to 11:59 PM, add 12 to the hour.
- Military → Standard: Convert the 24-hour time to 12-hour format. For 00:00 to 00:59, use 12:xx AM. For 01:00 to 11:59, use the hour as-is with AM. For 12:00 to 12:59, use 12:xx PM. For 13:00 to 23:59, subtract 12 from the hour and use PM.
