Consider clock of 24 hours instead of 2 divisional 12 hours. Midnight 12 is to be considered 0o' clock.

AM- ante meridian which means before noon ( before morning 12o' clock)

PM- post meridian which means afternoon (after morning 12o'clock)

A.M. / P.M. is a system used for telling time in 12 hours format, as in analog clocks.

A.M. is an abbreviation for ante meridiem , a Latin word meaning before noon. A.M. starts at 00.00.00 hrs at midnight and is till 11.59.59 hrs noon time.

P.M. is an abbreviation for post meridiem , a Latin word meaning after noon. P.M. starts at 12.00.00 hrs at noon and is till 11.59.59 night time.

12.00.00 hrs at midnight is 12 am, after that comes 1 am, 2 am,3 am......10 am, 11 am and 12 pm, after that comes 1 pm, 2 pm, 3pm......10 pm, 11 pm and 12 am.

The cycle goes on like that

I want to explain this in the different way. a way in which you never going to forget about the difference between A.M. and P.M.
first of all why we came up to the term A.M. and P.M.
To know the time human discover watches.A watch is small time piece, typical worn either on the wrist or attached on a chain and carried in a pocket, with wristwatches being the most common type of watch used today.A watch which is divided into two types on the basis of hour
(1)24 hour.
(2)12 hour.
Here we will concern about only 12 hour related clock.12 hour related clock have the answer of our question of A.M. and P.M. means.
Suppose you are in the dark room and you have no idea about, it is the time of star or sun.so someone who discover the answer of this question with the help of am and pm.it means we can easily know that what exactly our clock is trying to tell us about the
sun and star with the help of am and pm.
(1)A.M. :-
Ante Merediem , it is the part of the day when time is before midday.
example- In our country one o'clock in the night means 1:00 AM
(2)P.M. :-
Prime Merediem , it is the part of the day when time is after mid day.
example- In our country one O'clock in the day means 1:00 PM.
I hope above information is answer of all your query about AM and PM.

Basically there are two types of time formats one is a 12 hour format and another is 24 hour format.

In this 12 hour format ,
A.M and P.M are included .A. M means Anti -meridian and P.M means Prime meridian.

So A.M starts from NIGHT 12:00 to 12:00 in the afternoon. Similarly P.M starts from 12:00 in the afternoon to 12:00 in the NIGHT.
