How to Read Military Time
When keeping hours in this fashion, the day starts at midnight and is written as 00:00. The last minute of the day is written as 23:59, or one minute before the next midnight. Sometimes you may see 00:00 written as 24:00. Both are acceptable. A usage example showing the 12 hour clock vs military time would be a time table showing 4:00 pm to 12:00 midnight. This would be written as 16:00 – 24:00. Another example highlighting the difference between the two would be to show that 10:15 am is written as 10:15 in military time but 2:30 pm is written as 14:30.
This method of keeping time is most commonly used by the military, government, public transportation, hospitals, meteorologists, astronomers, those employed in emergency services, and also with computers. When speaking in military time, 07:00 may be stated as “zero seven hundred” or “oh seven hundred”. Also, in the military, these time stamps are often written without the colon, so 07:52 would rather be written 0752.
Time stamps referencing Greenwich Mean Time (GMT for short – often interchanged with Coordinated Universal Time/UTC) is denoted by a “Z” at the end, and is written as 0752Z. The local time is denoted by a “J” at the end, and the eastern time zone is denoted by an “R” at the end. Each of the zones have a corresponding letter and name.

The 24-hour clock is a way of telling the time in which the day runs from midnight to midnight and is divided into 24 hours, numbered from 0 to 24. It does not use a.m. or p.m. This system is also referred to (only in the US and the English speaking parts of Canada) as military time[1] or (only in the United Kingdom and now very rarely) as continental time. In some parts of the world, it is called railway time. Also, the international standard notation of time (ISO 8601) is based on this format.
A time in the 24-hour clock is written in the form hours:minutes (for example, 01:23), or hours:minutes:seconds (01:23:45). Numbers under 10 usually have a zero in front (called a leading zero); e.g. 09:07. Under the 24-hour clock system, the day begins at midnight, 00:00, and the last minute of the day begins at 23:59 and ends at 24:00, which is identical to 00:00 of the following day. 12:00 can only be mid-day. Midnight is called 24:00 and is used to mean the end of the day and 00:00 is used to mean the beginning of the day. For example, you would say "Tuesday at 24:00" and "Wednesday at 00:00" to mean exactly the same time. However, the US military prefers not to say 24:00 - they do not like to have two names for the same thing, so they always say "23:59", which is one minute before midnight.
24-hour clock time is used in computers, military, public safety, and transport. In many Asian, European and Latin American countries people use it to write the time. Many European people use it in speaking.
Many digital wristwatches and clocks can display the time of day using the 24-hour clock.
In railway timetables 24:00 means the end of the day. For example, a train due to arrive at a station during the last minute of a day arrives at 24:00; but trains which depart during the first minute of the day go at 00:00.
To write shop opening hours until midnight use, for example, "00:00–24:00", "07:00–24:00".
Advantages over the 12-hour clock system:
- Fewer confusions between morning and evening; e.g. 7 o'clock in the evening is called 19:00.
- People do not have to figure out if noon is 00h00.m.24 or 12hmr to calculate duration.

The 12-hour clock is a way of dividing the 24 hours of the day into two sections. The two halves are called ante meridiem (a.m.) and post meridiem (p.m.).
Both names are from Latin, and numbered from 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Time from midnight to noon is a.m. and from noon to midnight p.m. The table at right shows how it relates to the 24-hour clock.
