What is AM?
First of all, it must be understood that a day is made up of 24 hours, and these 24 hours are separated into two segments AM and PM, each comprising 12 hours. Taking into account that an hour has 60 minutes, therefore, each segment has 720 minutes.
AM is a time concept and an abbreviation of (Ante meridiem), which is a Latin term and an adverbial phrase that literally means “Before Noon”. The hours covered by the term AM range from the hour after midnight (00:00) to the hour before noon (12:00).
In another way, it can be explained that AM goes from 00:00 (Midnight) to 11:59 in the morning.
What is PM?
This is another term and abbreviation of Latinism, which means (Post Meridiem), which in Spanish means “After Noon”. This time block, as its name indicates, refers to all the hours reached between noon (12:00) and midnight (11:59).
It should be mentioned that this time system is used mostly in Latin American countries and in Canada. It is because, in other countries.
Relationship between AM and PM
Both terms (AM and PM) represent the way in which the 24 hours of the day are divided.
Each of these two segments is made up of 12 hours. On the other hand, it should be noted that each day begins at 00:00 am (Midnight), and ends at 11:59 pm; or to be more exact at 11 hours 59 minutes and 59 seconds Post Meridiem.
AM vs. PM
The only difference between these two time segments is that AM (before meridiem) refers to the hours from 00:00 to 11:59 in the morning, on the other hand, PM (post meridiem) are the hours from 12:00 p.m. to 11:59 p.m. If we observe, these two time segments refer to the Latin word meridiem, which in this case we can translate as noon. For this reason, we can translate AM and PM as follows:
- AM: before noon
- PM: after noon
