Military Time Converter

The Military Time Converter instantly translates between the 12-hour standard clock and the 24-hour military time format used by armed forces, hospitals, emergency services, airlines, and international organizations worldwide. Whether you need to convert 1400 to 2:00 PM or figure out what 11:45 PM looks like on a 24-hour clock, this tool makes the process effortless and error-free.

Military time, also known as the 24-hour clock, eliminates the ambiguity of AM and PM designations. Instead of cycling through 12 hours twice per day, military time runs from 0000 (midnight) to 2359 (one minute before midnight), giving each minute of the day a unique four-digit code. This precision is critical in contexts where misreading AM from PM could have serious consequences — scheduling surgeries, coordinating troop movements, managing flight timetables, or dispatching emergency responders.

The format is read aloud using specific terminology. 0000 is pronounced 'zero hundred hours,' 0630 is 'zero six thirty,' 1300 is 'thirteen hundred hours,' and 2245 is 'twenty-two forty-five.' The word 'hours' is typically appended when speaking, but omitted in written schedules. NATO and most military organizations worldwide standardize on this system for all official communications.

Understanding the conversion rules is straightforward. For AM times, the military equivalent simply drops the colon and uses a leading zero for hours below 10: 6:00 AM becomes 0600, 11:30 AM becomes 1130. Midnight (12:00 AM) is the special case 0000. For PM times, add 12 to any hour from 1:00 PM through 11:59 PM: 1:00 PM becomes 1300, 6:45 PM becomes 1845, and 11:59 PM becomes 2359. Noon (12:00 PM) stays as 1200.

Beyond military use, 24-hour time appears on train schedules throughout Europe and Asia, hospital shift records, aviation logs, scientific data timestamps, and computer systems. Many countries use it as the default timekeeping standard, making familiarity with the conversion a genuinely useful skill for travelers and professionals alike.

This converter handles both directions — enter a standard 12-hour time with AM/PM to get the military equivalent, or enter a four-digit military time to decode it into familiar 12-hour format. Use it for scheduling, travel planning, reading international timetables, or simply building intuition for the 24-hour system.
