This quiz about time is going to look at the 24 hour clock. This clock is used extensively, for example: in computers, in the military and in transport.

Using the 24 hour clock removes all possibility of making a mistake with the time, for example: 'Meet me at 6 o'clock'. Is that 6 o'clock in the morning or in the evening? The use of 'am' and 'pm' doesn't always help because not all people know what they mean: pm = post meridiem = between 12 noon and 12 midnight; am = ante meridiem = between 12 midnight and 12 noon.

Some adults find the 24 hour clock difficult to remember. 16:18 is not as easy as nearly twenty past four, is it? It is a useful thing to learn and you should find it easier than adults. Why? Because you have grown up with computers which always show the time in 24 hours.

This is read as 'zero zero hundred hours'. Note: The day begins at midnight, and the last minute of the day begins at 23:59 and ends at 24:00 BUT this is shown as 00:00. Some people do use 24:00, for example: 'Open from 00:00 to 24:00' - this shows that the business is open for the whole 24 hour period. To use 'Open from 00:00 to 00:00' might be a bit confusing. In general, avoid using 24:00 when telling the time
