# 24 hour clock

Converting between 12 and 24-hour time

What is 12-hour time?

What we see on a clock with hands, it is marked 1 to 12 to show the time. This is shown on an analogue clock.

How many hours are there in a day? 24

A 24-hour day is divided into 2 parts of 12 hours each, AM and PM

AM stands for ante-meridiam (Latin term meaning before midday)

PM stands for post-meridiam (Latin term meaning after midday)

What is 24-hour time?

We see this system of time written in 4 digits and describe it in ‘hundred hours’. It is shown on a digital clock.

24-hour system is used everyday in France and throughout Europe. It is used specifically by scientists and the military because it so precise.

The main reason why 24-hour time is described in hundred hours is to avoid confusion with 12-hour time, specifically regarding the hours before midday. For example 03:00 can’t be described at ‘3 hours’ because it sounds like a length of time rather than a reading, so ‘three hundred hours’ is used. The ‘hundred’ is another way of saying :00.

How many hours are there in a day? 24

A 24-hour clock is not divided into 2 parts of 12 hours each but is a continuous period of 24 hours

How do we convert 12-hour time to 24-hour time? Remember the AM hours remain the same.

Add 12 to the hours and keep the minutes the same.

9.45 PM = 9+12 = 21:45

How do we convert 24-hour time to 12-hour time? Remember the AM hours remain the same.

Subtract 12 from the hours and keep the minutes the same.

21:45 = 21-12 = 9.45 PM
