Is 12pm noon or midnight?
12pm is noon. Because “pm” stands for “post meridiem”, and “meridiem” means noon. I know this sounds like I’m saying 12pm is 12 hours after noon, and I don’t know why the English language is like this. But it is what it is.
AM is morning. PM is afternoon
Okay, so I know that 12pm is a bit confusing, and perhaps even a contradiction. But knowing the difference between AM and PM is easier when you know what they stand for.
AM stands for Ante Meridiem. This is any time before midday. From 12am at night to 11:59am in the morning.
PM stands for Post Meridiem. Any time after midday. From 12pm in the afternoon to 11:59pm, which is when most of you will probably be asleep.
Meridiem is to do with geography
One of the words we’ve used a lot so far in this article is “Meridiem”, and for the most part it means “noon”. But the reason we associate these words with the afternoon is due to the Meridiem line.
Planet Earth has many lines that separate the different parts of the word. The best way to think of the Meridiem line is to imagine the equator as Earth’s X-Axis, and the Meridiem as the Y axis.
The position of the sun along the Meridiem line determines what time of day it is. I know it’s complicated, but that’s the long and short of it.
Midday is the middle of the day
Another word for noon is midday. As the name suggests, midday is in the middle of the day. At this point, you have had 12 hours of that day so far, and you have another 12 hours left. Usually, this will be the time of the day when the sun is at its highest point.
Of course, this isn’t always the case, but generally speaking, if you want to gamble on when the sun will be highest, midday is probably your best bet.

Because PM stands for “post meridiem” and “meridiem” means noon, this shouldn’t be the case. But the thing with English is it often doesn’t make all that much sense. Thankfully, after reading this article, you will now know the right time when you’re next asked.
