How to read military time
Military time counts the hours of the day from 00 to 23, followed by two digits for minutes, so 1530 is read as fifteen-thirty and equals 3:30 PM. For hours 13 through 23, subtract 12 to get the afternoon or evening time; 0000 is midnight and 1200 is noon.
Need a date in day-of-year form as well? The military Julian date calendar converts calendar dates to YYDDD and YYYYDDD codes.
Questions about this tool
How does the converter distinguish noon and midnight?
The converter uses a time of day from 0000 through 2359. It displays 0000 as 12:00 AM and 1200 as 12:00 PM. This page treats four digits as a clock time rather than an elapsed duration, and rejects minute values above 59 instead of silently normalizing them.
Can I enter military time with a colon?
Yes. Both a four-digit value such as 1530 and a colon-separated value such as 15:30 are accepted. The output shows the corresponding AM/PM clock time. Use leading zeros when you need an unambiguous four-digit representation on a training schedule or other document, and confirm the required local format.
Does this time conversion change the time zone?
No. The converter changes the clock notation only. It does not translate between local time and UTC, apply daylight-saving rules, or infer a time zone from your location. A schedule crossing locations needs its time zone specified separately; the same four clock digits can refer to different moments in different zones.
Why is 2400 not accepted as an ordinary time of day?
This converter uses the unambiguous 0000–2359 daily clock range. Some documents use 2400 to describe the end of a named date, which also requires a date convention. Enter 0000 for midnight here and specify the intended date separately when a schedule distinguishes the start and end of a day.
