Convert military time to standard time and back as you type – with a live clock, spoken time and a printable 24-hour chart.
A short video walkthrough of the 24-hour clock — why 1300 is 1:00 PM, why midnight is 0000, and the same conversion rules the converter above uses.
AI Time Tracker runs in the background on your Mac or Windows computer and logs your work hour by hour — in 24-hour time, every late-night fix counted. No conversions, no manual entries, no end-of-shift guessing.
Military time is a 24-hour clock written as four digits, without a colon: 0930 means 9:30 AM and 2130 means 9:30 PM. There is no AM/PM — the hour number itself tells you the time of day.
If the first two digits are less than 12, keep them and add AM: 0830 → 8:30 AM. If they are 12 or more, subtract 12 and add PM: 2130 → 9:30 PM. Midnight (0000) is 12:00 AM, noon (1200) is 12:00 PM. Type the time into the converter above and the result appears as you type — no button needed.
For morning hours, keep the number and add a leading zero if needed: 9:30 AM → 0930. From 1 PM onwards, add 12 to the hour: 9:30 PM → 2130. 12:00 AM (midnight) → 0000, 12:00 PM (noon) → 1200.
Military time is spoken with every digit named: 0930 is "zero nine thirty hours", 1600 is "sixteen hundred hours", 2305 is "twenty-three oh five hours". The converter shows the spoken form for every time you enter, so you can learn both the reading and the writing conventions.
Military time is standard anywhere a 12-hour clock could be misread — and where a mistake costs more than a missed alarm:
If your shifts start at 0630 and end at 1845, you convert time in your head every day. You do not have to convert it in your timesheet too: the free AI Time Tracker records your work in 24-hour time directly from your computer activity, so your timesheet fills itself while you focus on the shift.
Labor law does not use AM and PM. In the United Kingdom, night work is legally defined as 23:00 to 06:00 (Working Time Regulations 1998), and across the EU, national law defines night time as a window that must include 00:00 to 05:00 (Working Time Directive 2003/88/EC). US federal employees on permanent schedules earn night pay for work between 18:00 and 06:00. Whenever regulators, unions or contracts compute a night premium, they do it from unambiguous 24-hour timestamps — like "0630–1830" and "1900–0700".
That matters on the shop floor, not just in court. Most shifts that trigger night-work rules cross the 23:00–06:00 window — and every conversion in your head is a chance to misread a clock-in. Read "0630" as "1830" once and a whole night's differential lands on the wrong side of the week. Records typed up after the fact, from memory, are exactly the records that fail an audit or a wage claim.
If your shifts run through the night window, let the record keep itself: the free AI Time Tracker logs your working hours exactly as they happen, in unambiguous 24-hour time — no conversions, no retrospective guesswork, ready for the compliance checklist when you need it.
The converter deals with any time of day; this chart covers the full 24 hours. Click Print chart / Save as PDF above to take it with you.

The 30-minute marks follow the same pattern — 0130 is 1:30 AM, 1345 is 1:45 PM. For any value in between, use the converter above.
Military time is the 24-hour clock written as four digits without a colon. The day runs from 0000 (midnight) to 2359 (11:59 PM). The first two digits are the hour, the last two are the minutes — so 1415 means 2:15 PM. It removes the AM/PM ambiguity, which is why the military, hospitals, airlines and emergency services rely on it.
Insert a colon between the hours and minutes. If the hour is below 12, it is AM as written (0830 → 8:30 AM). If it is 12 or above, subtract 12 and it is PM (1830 → 6:30 PM). Midnight 0000 is 12:00 AM and 1200 is 12:00 PM. Or type the time into the converter above — it converts as you type.
Morning hours stay the same with a leading zero — 9:15 AM → 0915. From 1:00 PM add 12 to the hour — 4:15 PM → 1615. Special cases: 12:00 AM midnight → 0000, 12:00 noon → 1200. Then write the digits together without a colon.
Read every digit out, followed by "hours": 0900 is "zero nine hundred hours", 1630 is "sixteen thirty hours", 0805 is "zero eight oh five hours". When two digits could merge, "oh" marks the zero — 1705 is "seventeen oh five hours", not "seventeen five hours". The converter shows the spoken form for any time you enter.
Both describe the same instant. 0000 is midnight at the start of a day, 2400 is midnight at the end of the previous one — so 0000 Thursday and 2400 Wednesday are the same moment. Printed schedules use whichever reads clearer; this converter accepts both 0000 and 2400 and normalises to 0000.
Nurses charting medication times, pilots reading flight plans, train crews on timetables, emergency dispatchers logging calls and international teams avoiding AM/PM mix-ups. If that is your workday, converting every clock reading gets old fast — the free AI Time Tracker logs your hours automatically in 24-hour time.
