ガイド
The Military Time Converter reads a time in whichever common format you paste it in — 12-hour with AM/PM, plain 24-hour, or military numeric — and reports all four representations at once: 12-hour, 24-hour, military numeric ("1430"), and the spoken military form ("Fourteen Thirty Hours"). No need to pick a direction first; the format is auto-detected from the input itself.
Military (and aviation, hospital, and international) time avoids the AM/PM ambiguity of the 12-hour clock by counting straight through to 24: 0900 is 9 in the morning, 2100 is 9 at night. It's written as four digits with no separator — hours first, then minutes — and pronounced digit-by-digit rather than as one number, which is what the "spoken" row reproduces.
How to use it
Type a time into the single field:
- 12-hour — include AM or PM, e.g.
2:30 PMor11:59pm. Seconds are optional (2:30:15 PM). - 24-hour — a colon-separated time with no AM/PM, e.g.
14:30or09:00:45. - Military numeric — four digits for hours+minutes (
1430), or six digits to include seconds (143015). No colon, no AM/PM.
Leave the field blank to convert the current time.
How is the format detected?
The three accepted shapes don't overlap, so detection is unambiguous: a trailing AM/PM marker means 12-hour, a colon with no AM/PM means 24-hour, and bare digits (4 or 6 of them) mean military numeric. Whichever one you typed, every other representation is computed from it.
How is the spoken form built?
Hour and minute are each read as their own English number word. A single-digit hour or minute is spoken with a leading "Zero" (so 0900 reads "Zero Nine Hundred Hours", the way military radio traffic says "zero-nine-hundred"), and a minute of 00 reads as "Hundred". Seconds aren't included in the spoken form — military time is conventionally spoken to the minute.
Is my data sent anywhere?
No. The conversion runs entirely in your browser, so nothing you type leaves your device.
