Difference Between AM And PM with Diagram

When we talk about the hours of the day, it isn’t the same when our timekeeper shows am or pm. Everything and that these two acronyms partake schedules, they’re fully different. In this essay we explain all their differences and commonalities so that when looking at your watch you can distinguish them impeccably.  AM And PM with Diagram

AM vs PM  AM And PM with Diagram

Main differences:

The main and only difference between these two hourly members is that AM (before meridiem) refers to the hours from 0000 to 1159 in the morning, while PM (post meridiem) refers to the hours from 0000 to 1159a.m. 1200 until 1159 at night. As we can see, these two hourly portions pertain to the Latin word meridiem, which in this case we can paraphrase as noon. For this reason, we can paraphrase AM and PM as follows:

  • AM : before noon
  • PM : after noon

What is AM?  AM And PM with Diagram

The first thing we learn about the time system is that a day is made up of 24 hours. And these 24 hours are divided into two members AM and PM, each one comprised of 12 hours. Taking into account that an hour has 60 flashes, either it can be said that each member contains 720 flashes.

Now, AM is a time generality and an bowdlerization of”Ante meridiem”, which is a Latinism. And an adverbial expression that literally means”Before Noon.”The hours covered by the term AM range from the hour after penumbra (0000) to the hour before noon (1200).

In other words, AM runs from 0000 ( Penumbra) to 1159.

 What is PM? 

Now, as far as PM is concerned, this is another term and bowdlerization of Latinism. Which means”Post Meridiem”, which in Spanish means”After Noon.”This hourly block, as its name indicates, refers to all the hours between noon (1200) and penumbra (1159).

It should be noted that this time system is used generally in Latin American countries and in Canada. This is because, in other countries, the so- called military schedule is used, which will be mooted thereafter.

Relationship between AM and PM

As we’ve said, these two terms (AM and PM) represent the way in which the 24 hours that the day contains is divided.

Each of these two portions is comprised of 12 hours.

On the other hand, it should be noted that each day begins at 0000 am ( Night), and ends at 1159 pm; or to be more precise at 11 hours 59 beats and 59 seconds Post meridiem.

History

Now, it should be noted that this 12-hour split is nothing new. But rather the twelve-hour timekeeper was developed in the middle of the equivalent prime BC. During these fair 4000 epochs, the timekeeper has had different forms, and different functions, but it was from the 16th century that it acquired the appearance that it has moment.

The 12-hour cycle comes through day and night, since historically the first 12 hours passed during the day, where time was established hung on the shadow of the sun.

On the other hand, the other twelve hours were established taking into account the position. And relationship of the moon and the stars.

24h time system

Ultimately, let’s mention the military time system, where instead of counting 12 in 12 hours. The day runs from umbra to umbra, that is, from 0000 to 2300.
