Frequently asked questions

What's the one rule to remember?

From 1:00 PM onward, add 12 to the hour: 5:30 PM is 1730, 11:00 PM is 2300. Morning hours just get zero-padded: 9:15 AM is 0915. Coming back, any military hour of 13 or more loses 12 and becomes PM.

Is midnight 0000 or 2400?

0000 is the standard — it begins the new day. Some military and scheduling contexts write 2400 to mean end-of-day on the previous date (a shift 'until 2400 Friday'), but as a moment on the clock it's the same instant as 0000 Saturday. This tool uses 0000.

How is military time spoken aloud?

Without the colon: 1730 is 'seventeen thirty'. Even hours take 'hundred' — 0900 is 'zero nine hundred', 1400 is 'fourteen hundred'. In strict military radio usage a time zone letter follows, most famously Z for UTC ('Zulu time').

Why do hospitals and pilots insist on it?

Because 12-hour time has a built-in failure mode: 12:00 AM vs PM confuses people constantly, and a smudged or missing AM/PM on a chart is a 12-hour medication error waiting to happen. A 24-hour timestamp is unambiguous with no annotation — that's the entire argument, and it's a good one.

About this tool

The military time converter translates both directions as you type — 1730 to 5:30 PM, 9:15 am to 0915 — with a live clock showing the current time in both systems and a full 24-hour reference chart. It also covers the two conversions everyone stumbles on: midnight is 0000 (starting the new day) and noon is 1200, with no 12 AM/PM ambiguity — which is exactly why hospitals, aviation, and the military use the format, and why it's simply the everyday clock in most of the world.
