People Are Amazed After Discovering True Meaning Of AM And PM

People are just starting to understand what AM and PM mean on a 12-hour clock.

Sometimes we accept certain things without thinking about them too much.

One of those things is the significance of AM and PM when we talk about the time on a 12-hour clock.

But recently, someone on TikTok has asked for an explanation about it.

Amaya Clarke, in a post that more than 8,000 people have seen, poses the question: "What does AM and PM stand for?"

A lot of people in the comments thought it might mean 'after midnight' and 'past midday,' which seems logical.

Others made guesses that were somewhat similar, like 'at morning' and 'past morning.'

Although those guesses are somewhat close, there is a real reason behind the use of AM and PM in timekeeping.

According to the Royal Museums Greenwich, which is the institution associated with Greenwich Mean Time, they provide an explanation: "AM stands for the Latin ante meridiem, translating to 'before midday'."

"This is the time before the sun has crossed the meridian."

"PM stands for post meridiem or 'after midday' – after the sun has crossed the meridian."

The experts provide an explanation: "At exactly 12 noon, the Sun is at its highest point in the sky and directly over the meridian."

"It is, therefore, neither 'ante' (am) nor 'post' (pm) meridian. At 12 midnight it also neither am nor pm."

While some individuals in the comments managed to guess it correctly, there were others on social media who were unaware of this information.

A particular individual expressed: "Well I didn't know this and I'm in my 50's! Was never taught this in school either."

"If I'm honest, I'd never even thought about it, just called it morning and afternoon."

"I don't think they taught us that in school. Seems like new information to me," another added.

This is why it is inaccurate to refer to midday as 12 pm.

Another person shared: "I'm in my 30s and never heard of this and no they never taught this in any school I went to lol."

However, there were some who claimed that they already knew this and considered it to be common knowledge.

"I only know it because we were taught it in Latin. Not sure others would," a commenter wrote.

Another person stated: "There used to be a thing called school that taught stuff like this."

"Anyone who doesn't know this shouldn't be allowed to handle any kind of device or be allowed to stay awake after 7 pm," a user thought.
