Military Time Converter
Convert one time instantly, or rewrite a labeled schedule without losing its structure.
This changes time notation only. It does not verify a schedule, infer a date, or convert a time zone or Zulu designator.
Convert a single time without guessing
Enter four-digit military time such as 1730, colon-form 24-hour time such as 17:30, or standard time such as 5:30 PM. The result shows all three notations together. A short value such as 7:30 is left unresolved because it does not say AM or PM and lacks the leading zero that makes 07:30 explicit 24-hour notation.
Rewrite the schedule you already have
Schedule mode changes recognized time tokens while preserving the surrounding labels, line breaks, and separators. For example, Opening 9am–6:30pm becomes Opening 0900–1830. Going the other direction, Night shift 2200–0600 becomes Night shift 10:00 PM–6:00 AM (+1 day).
Unclear and invalid values are not silently corrected. They stay in the output and appear in a warning list so you can fix only the affected part of the schedule.
0000 and 2400 need different date meaning
0000 represents midnight at the start of a day. 2400 can represent midnight at the end of the named day. When this tool normalizes 2400 to 0000, it marks a one-day rollover. If the input is 2026-09-05 2400, the normalized result is 2026-09-06 0000, not 0000 on September 5.
What the converter deliberately does not do
Military time is a notation, not a time zone. This page does not infer Zulu time, UTC, a location, daylight-saving rules, or a missing date. It also does not certify that a pasted schedule is complete or authoritative. Review conversions used for clinical, payroll, transportation, emergency, legal, or operational records against the governing source.
Quick conversion rules
| Input | Standard | Military |
|---|---|---|
| 0000 | 12:00 AM, start of day | 0000 |
| 0730 | 7:30 AM | 0730 |
| 1200 | 12:00 PM | 1200 |
| 1730 | 5:30 PM | 1730 |
| 2400 | 12:00 AM, next day | 2400 → next-day 0000 |
Frequently asked questions
What is 1730 in regular time?
1730 is 5:30 PM. For military times from 1300 through 2359, subtract 12 from the hour and add PM; the minutes stay unchanged.
Is midnight 0000 or 2400?
0000 marks the start of a day. 2400 can mark the end of a stated day or time range. They refer to the same boundary, but 2400 carries next-day meaning when normalized to 0000.
Why does the converter mark +1 day?
A range such as 2200–0600 crosses midnight, and 2400 is end-of-day notation. The marker prevents an overnight endpoint from looking earlier than its start. When an ISO date is supplied with 2400, the converter advances the date.
Can I paste a whole work schedule?
Yes. Paste labeled lines or time ranges and choose military time or AM/PM. The converter replaces recognized time tokens while keeping labels, line breaks, and separators. Ambiguous or invalid values stay visible with a warning.
Why is 7:30 considered ambiguous?
Without AM or PM, 7:30 could describe morning or evening in a 12-hour schedule. Use 7:30 AM or 7:30 PM, or add the leading zero 07:30 to state that it is 24-hour time.
Does military time include a time zone?
No. Military-style four-digit notation describes a clock time. A time-zone name, offset, or letter such as Z must be supplied and interpreted separately; this tool does not shift times between zones.
Is the conversion safe for official records?
The arithmetic is deterministic, but the tool cannot verify the source schedule, date, time zone, or organizational rules. Review any result used for healthcare, payroll, transportation, emergency, legal, or operational records.
