AM Full form / Full form of AM
The full form of Am is anti meridiem. it is a Latin word that means before midday. Am is useful in 12 hour clock to represent the time zone. There are two time zone in 12 hour clock format. Am and PM. Both AM and PM are used to differentiate the time of evening and morning.
The first zone AM starts from midnight 12:00 to afternoon 12:00 clock. They are presented 12:00 AM and 12:00 PM.
The second zone or PM starts from 12:00 midday from 12:00 of night. They are presented as 12:00 AM and 12:00PM respectively.
PM represents post meridiem which means “after midday”.
If you want to understand it by 24 hour format then first 1 to 12 hours are related to AM and 12 to 24 hours are related to PM.
Let’s understand it by a example
If I say I will come to you at 9:00 O’clock. Then the other person would not understand it because he can’t predict between 9:00 O’clock of before midday or after midday.
So these are represented as 9:00 AM or 9:00 PM.
I hope you understand the full form and meaning of AM and PM in time.
