Military Time Converter

1500 is 3:00 PM. For any military time of 1300 or later, subtract 12 from the hour: 15 − 12 = 3, so 1500 hours is 3:00 PM standard time.

Both refer to the same moment, but 0000 is the standard for the start of a day, and 2400 may denote the end of a day (a shift ending at 2400 Tuesday = 0000 Wednesday). Most systems, including this converter, use 0000.

Whole hours read the number plus "hundred": 0800 is "zero eight hundred hours", 2000 is "twenty hundred hours". With minutes, read all four digits: 0845 is "zero eight forty-five", 1505 is "fifteen zero five".

Add 12 to the hour, unless it's 12 PM itself: 3:30 PM → 3 + 12 = 15 → 1530; 8:15 PM → 2015. Noon stays 1200, and 12:30 PM is 1230 — the add-12 rule only applies from 1:00 PM onward.

Because it removes AM/PM ambiguity. A medication order for "7:00" could be 0700 or 1900 — a 12-hour error. Aviation, nursing, emergency services, and militaries worldwide use the 24-hour clock so each of the 1,440 minutes in a day has one unambiguous name.

The numbers are identical; the conventions differ slightly. Military style writes times without a colon (1530), often appends "hours", and may use 2400 for end-of-day; the civilian 24-hour clock (used across Europe and in timetables) writes 15:30 with a colon and always uses 00:00 for midnight.
