To tell what time it is? And how we need to see a time clock?

**Time – A.M. and P.M.**

There are 24 hours in a day.

The face of a clock has numerals from 1 to 12.

The hour hand takes two full rounds in 24 hours time clock.

The first round of the hour hand completes at 12 o'clock midday, also called **12 noon**.

The second round of the hour completes at 12 o'clock midnight.

The hours from midnight to noon are known as **a.m.**

The hours from noon to midnight are known as **p.m.**

These hours are in the afternoon, evening or night.

a.m. or A.M. stands for **Ante Meridian**

p.m. or P.M. stands for **Post Meridian**

We do not write a.m. or p.m. with 12 o'clock. It is written as **12 noon** and **12 midnight**.

There is no o'clock written with a.m. or p.m. 8 o'clock in the
morning is written as 8 : 00 a.m. 2 hours after noon is written as 2 :
00 p.m.

The hours and minutes are separated by a colon (**:**)
