Convert between military time (24-hour clock) and standard 12-hour AM/PM format instantly. Includes a full reference chart and current time in both formats.
Military time is the 24-hour clock system where hours run from 00:00 (midnight) to 23:59 (one minute before the next midnight). It eliminates AM/PM ambiguity — 1400 is always 2:00 PM, not 2:00 AM.
For hours 00-11: add AM (0000 = 12:00 AM, 0900 = 9:00 AM, except 0000 is 12:00 AM). For 1200: 12:00 PM. For hours 13-23: subtract 12 and add PM (1400 = 2:00 PM, 2300 = 11:00 PM).
1500 military time = 3:00 PM. Subtract 12 from hours above 12: 15 - 12 = 3, so 1500 = 3:00 PM.
Midnight is 0000 hours (also written as 2400 hours at the end of a day). The next minute is 0001. 2400 and 0000 refer to the same moment.
The military, aviation, healthcare (hospitals, pharmacies), emergency services (police, fire, ambulance), railways, and most countries outside the US and UK use 24-hour time as the standard.
12:00 PM is noon (midday). 12:00 AM is midnight. In military time: noon = 1200, midnight = 0000 or 2400. The AM/PM system is confusing at these exact points — which is why 24-hour time is clearer.
Say the four digits: 0900 = "zero nine hundred hours". 1430 = "fourteen thirty hours". 0015 = "zero zero fifteen hours". Never say "fourteen hundred and thirty" — just state the digits.
