Stage 1
AM and PM
Lesson
You may already know that there are $24$24 hours in a day but clocks only go to $12$12. Why? Well, for one thing, we would need a very big clock to fit $24$24 numbers around it! People also worked out a long time ago that they could split the days into two lots of $12$12 hours and just make note of whether it was morning or afternoon. Let's learn more about this now.Remember!
AM means "before midday" and PM means "after midday."

How about some LATIN!
The abbreviation AM, comes from the latin "ante meridiem" which means before midday and the abbreviation PM comes from the latin "post merideim", meaning after midday.
