A community for Cartographers with nothing left to lose.
Rules:
Don't be awful Lemmy Guidelines Still Apply.
No direct upload images This is hosted on Lemm.ee- to post images, you must use an image upload service like Imgur to post maps.
We are agents of chaos I've created this to be the alternative to the community I used to manage on the website that shalt not be named "mapporncirclejerk"
Live and let die Meme trends happen, so please don't message mods asking to take down maps that are repetitive to a bit.
Reposts Vs. Covers Not all reposts are evil- if someone posts something that has been done years ago, it serves to bring old memes to the new users. I call these meme covers. However it can be done in excess which makes it a repost and spam. Mods will determine if a post is a cover or a repost.
No impersonating mods I can't believe I had to make this rule.
No harassing mods on an appeal We can talk it out, and we will be acting in good faith when making decisions. If you disagree with a removal, you are free to message for clarification or to appeal by giving some added context.
Bans Bans will be set to a maximum of 365 days for humans, and a minimum of 365 years for bots. I believe people can change, so if you are banned for good reason, do know that it is not permanent, it is just a way to say "take time to grow and come back when you are ready".

What's the h for?
Hour. Just a weird way to say 12:00 and 15:00 or 3pm and whatever 12:00 is in am/pm talk
12am is midnight and 12pm is noon. But most people just say "noon" or "midnight" because it's less confusing.
That is confusing. "PM" is "post meridian" or, as I understand it, after the middle. One would think it wouldn't be PM until 12:01 or at least 12:00:01.
Which is why I, as you said, use "noon" and "midnight."
I can never remember it properly either but when someone reminds me (thanks samus12345) which way around it is it does kind of make sense.
If you think of 12:00 as literally an infinitesimal slice of time it's not really possible to give it an am/pm distinction, as it is literally the devider between the two. BUT, in a more real-life approach 12:00 is probably not an infinitesimal slice of time but the minute after a digital clock flipped to 12:00. That can be 12:00:00.00004 or 12:00:30 or 12:00:59.999944. And all those are indisputably pm.
Couldn't it be 00:00 PM? So zero time since meridian?
That's not a bad suggestion, but may interfere with 24 hour clocks.
That's why you switch the clocks over to 24 hours
I can't tell if you're agreeing or arguing with me.
Correct - technically, noon is neither am nor pm, but clocks and the like have to have SOMETHING there, so am for midnight and pm for noon was arbitrarily chosen.
