Watching 24 and it says "the following takes place between 12pm and 1pm"
Now they of course mean from noon till 1 pm.
But... is that correct?
I thought 'officially' 12pm was midnight, noon having to be 12am. 1 minute AFTER noon is when PM starts, so with 12.01

I looked it up a while ago, and found that even most native speakers don't really know how it's supposed to be.
Anyway who can confirm that what I said above is correct?

Then why is Jack Bauer (24) so stressed out? He's got from midnight until 1 in the afternoon. Plenty of time!

When it is Midnight it is considered 12am

When it is Noon it is 12pm.

So he has the afternoon between 12pm-1pm = 1 hour.

agreed

It's midday.

The way I learned to keep it straight, is to think about telling someone what time it is.

If you are looking at a clock, and waiting until it has a 12 on it followed by two zeroes (assuming it's digital)...

...by the time it takes for you to turn to the person who you want to tell, it's something you know. That is, if it's just noon, by the time you turn and get out the words "it's twelve...something," it's afternoon, and you know that, so you have to say "twelve P.M."

Just use military time

12 pm is lunchtime for many businesses. therefore it is noon. Gary Cooper is HIGH noon.

Latin ante meridiem "AM" (before midday) and post meridiem "PM"(after midday)

so, 12 AM is midnight and 12 PM is noon.

We do over here It's how everyone learns to read the clock. We don't pronounce it like the military, "sixteen hundred hours", but "6 o'clock".
It is much easier, never having to think about AM and PM. I always have to think about that, even after years of dealing with it

Thanks!
And yes, spelling is another thing yet again, pfff...
I needed it when writing my book, Googled what was the right way as using the versions with . in it isn't handy in a book. Sometimes you end the sentence with the time, then do you write two periods? Too confusing.
I believe my editor edited it to "AM" but not 100% sure anymore now, haha.
