Military time is the 24-hour clock written as four digits, from 0000 at midnight to 2359. Because each hour has a unique number, there is no need for AM or PM.

Subtract 12 from the hour: 18 − 12 = 6, so 1800 is 6:00 PM. Any hour of 13 or above converts the same way.

Yes — every clock, converter and chart works in any modern browser on any device.

No. The clocks read your device's own time and everything is calculated locally; nothing is sent anywhere.

The clock above shows it live: four digits, hours 00 to 23 followed by minutes. It reads your device's own clock, so it always matches the time where you are.

Military time is normally written to the minute, as in 1430. Seconds are added only when precision matters, and are usually spoken rather than written.

1200 is noon. Midnight is written 0000 at the start of a day, and sometimes 2400 to mark the end of one.

Read the hour, then the minutes: 1430 is "fourteen thirty". On the hour you say "hundred", so 0700 is "zero seven hundred".

Add 12 to the hour and drop the PM: 6:45 PM becomes 1845. The single exception is noon, where 12:00 PM stays 1200 rather than becoming 2400.

If the hour is 13 or more, subtract 12 and add PM, so 2015 becomes 8:15 PM. Hours from 01 to 11 keep their number and take AM.

0000 is 12:00 AM, midnight at the start of the day. The same instant can be written 2400 when marking the end of the previous day.

Yes. Minutes never change between the two formats — only the hour does — so 3:45 PM converts to 1545 with the 45 untouched.

It maps each of the 24 hours to its civilian equivalent so you can convert at a glance, and shows how each hour is spoken.

Because 2359 is the last minute of the day. The next minute is 0000, the start of the following day.

Yes — the page prints cleanly, and the hour rows stay in order so it works as a desk reference.

Yes — Zulu time is UTC expressed in military four-digit format with a Z suffix. The instant is identical; only the notation differs.

For practical purposes yes. GMT is the older astronomical term and UTC is the modern atomic standard, but for everyday scheduling they refer to the same clock.

J, or Juliet, is reserved for the observer's own local time, so it never denotes a fixed offset the way the other letters do.

Subtract your UTC offset from your local time. The clock above shows both your offset and the resulting Zulu time, so no arithmetic is needed.

Use your browser's print command. The page is laid out so the hour list stays on one sheet.

Usually not — minutes are identical in both formats. The card only needs the hours, which is what makes it small enough to be useful.

It marks a time on the hour with no minutes: 1500 is spoken "fifteen hundred". Times with minutes drop the word, so 1530 is "fifteen thirty".

A date-time group: a compact stamp giving the day of the month, the time, the zone letter and the month, used to timestamp messages unambiguously.
