Many people in this world are writing AM and PM with the time from their childhood but most of them didn’t even know the actual meaning of both these words. Some of them thinks several times to know the meaning of AM and PM but didn’t get the meaning of these words. There are many people who have derived meanings of both the AM and PM by their own but the fact is that both the words are the abbreviations of four Latin words.
AM
First of all we should know the meaning of AM. AM is the abbreviation of Latin word Ante Meridiem, which means “Before Noon” or First Meridian.
PM
PM is also an abbreviation Latin word Post Meridiem which actually means “After Noon” or After Meridian. For example: If we write 2:00PM, it means that the time is 2 hours After Meridiem or After Noon.
It is an amazing fact that most of the people have written both the words many times in a day with time but they don’t know the meaning of AM and PM. However, all those people who have now got the actual meaning of AM and PM, should also tell other people as well to spread the knowledge.
