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 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, European countries, and transport. In many Asian, European and Latin American countries people use it to write the time. Many European people use it in speaking.

How the 24 Hour Clock is Used The 24 hour clock is a convention of keeping time where the day typically runs from midnight – midnight and it’s divided into twenty-four hours. The clock starts at 00:00 (that is, midnight) and it indicates the hours that have passed since then (that is, from 0 to 24).

AM/PM 24 Hour My time: 12:46:50 PM toll 1 USD - check currency. Amazon photos on pc.

Many models of digital wristwatches and clocks are available that display the time of day using the 24-hour clock.

In railwaytimetables 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.

A time zone refers to a place on earth that uses a uniform standard time in order to streamline legal, social, and commercial activities. The time zones are defined by the boundaries of countries. The largest difference between the time zones of two countries is 26 hours between the Howland Islands and the Line Islands.

Time Zones

The clocks in the world are under the regulation of the Coordinated Universal Time (UTC), which is not adjusted for daylight savings. In other countries, especially English speaking countries, the phrase Greenwich Mean Time (GMT) is used to mean the same thing as UTC. The first Coordinated Universal Time was officially accepted in 1963 while the official abbreviations of the aforementioned times were adopted later on in 1967. Therefore, time zones in the world are obtained from the UTC. An area on earth can either be ahead (+) or behind (-) the UTC, which means that UTC is 0 hours. Given that there are 24 hours in a day, it is logical to state that the biggest time difference between two points on earth would be 24 hours. The reason for this time difference is that one end would have a time of +12 hours UTC while the other would have a time of -12 hours UTC, which would mean a difference of 24 hours on a number line.

Biggest Time Difference On Earth

Some places on earth do not use the international time zones, that is, they do not use the UTC system of +12 and -12 hours UTC. Some areas on earth use time zones that exist but are not defined by the current time convention. Some areas on earth use a time zone of +13 hours UTC or even +14 hours UTC. Essentially, this means that areas with -12 hours UTC and +14 hours UTC will have a difference of a whole 26 hours, which is beyond the theoretical 24 hours. Areas with +13 hours UTC will have a difference of 25 hours from areas with -12 hours UTC.

With this information, then the biggest time difference between two places on earth is a whole 26 hours. The Howland islands, an unincorporated unorganized territory of the United States, use a time zone of -12 hours UTC on the far west of the earth. The Republic of Kiribati’s Line Islands, which have a time zone of +14 hours UTC, are on the far east of the earth. These two places, therefore, have the biggest time difference of 26 hours.

Close Proximity

Interestingly, despite having such a huge time difference, these areas are extremely close to one another in the Pacific Ocean. What this difference means is that two areas that are close to one another have an extremely minor time difference. For example, the Howland islands have a time zone of -12 hours UTC while the Line Islands use a time zone of the aforementioned +14 hours UTC. These time zones mean that Wednesday 22:15 in the former is Friday 00:15 in the latter, which is a difference of only two hours. The bigger time difference of 26 hours is only observed in the dates of the two places. The area with a positive time zone means that it is ahead in terms of the date.
