Military Time Converter — 24-Hour to AM/PM
1730 to 5:30 PM and back — plus the full 24-hour reference chart.
Military time runs the day from 0000 to 2359 with no AM/PM — the convention used by the military, aviation, healthcare, emergency services, and most of the world's written schedules. Converting is simple past noon (subtract 12 from the hour) but trips people up at the edges: midnight is 0000, noon is 1200, and 12:30 AM is 0030, not 1230. The converter below handles all of it both directions, and the chart covers every hour at a glance.
Pure notation conversion — no timezone shift. Military convention: the day starts at 0000 (“zero hundred”); 2400 is accepted as an end-of-day timestamp and normalised to 0000. Noon is 1200, midnight is 0000/12:00 AM.
How to use
Type a time in either field
24-hour input accepts 1730, 17:30, or 730 (= 0730). AM/PM input accepts 5:30 PM, 12 AM, or shorthand like 9:05p.
Read the spoken form
Whole hours are spoken as 'hundred' — 1700 is 'seventeen hundred hours', 0800 is 'zero eight hundred'. The result line shows the convention.

Frequently asked questions
- Is midnight 0000 or 2400?
- Both are used: 0000 marks the start of a day, 2400 the end of the previous one — 2400 Tuesday and 0000 Wednesday are the same instant. Most digital systems and this converter normalise to 0000; 2400 appears mainly on schedules to signal 'end of day'.
- How do I convert PM times quickly?
- Add 12 to the hour: 5:30 PM → 5 + 12 = 17 → 1730. Going the other way, subtract 12 from anything 1300 or later. The only special cases are the 12s: 12:xx AM becomes 00xx, and 12:xx PM stays 12xx.
- Is military time the same as 24-hour time?
- The clock is the same; the formatting differs slightly. Military usage writes times without a colon (1730) and speaks whole hours as 'hundred' ('seventeen hundred'). Civilian 24-hour notation — standard across most of Europe — writes 17:30 with a colon. This converter accepts both.
- Does this handle timezones?
- No — it converts notation only. For converting a time between cities, use the timezone converter.
