Days start at 0h, not 12h

It can't start at 12 hours if there are 24 segments.

And keep your letters out of it too.

Show me where is the zero here?

I have a clock that has 0 at the bottom, 6 in the 9 position, 12 at the top, and 18 in the 3 position.

That's fantastic and I want one, but it's a BCD clock. Binary would say 01100 001111 101101

The AM/PM bullshit:

AM: 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

Then the same for PM. Who counts like that? Whats after 12? 1! What?

The galaxy-brained group known as "Z~12~ + 1". "What if we did modular arithmetic but one-indexed."

Edit: Actually, wait, it's worse: zero-indexing but we represent the zero element in Z~n~ as 'n'. Kill it with fire.

[-] davidagain@lemmy.world 4 points 1 year ago

Is not 12+12Z the exact same coset as 0+12Z? Is 12 not the identity element? Must group theory follow computer science conventions?

[-] chonglibloodsport@lemmy.world 2 points 1 year ago

People who lived before the invention of zero counted like that!

[-] possiblylinux127@lemmy.zip 1 points 1 year ago

I have no idea if that's true but I believe it

[-] chonglibloodsport@lemmy.world 4 points 1 year ago

The idea of zero being a number rather than the absence of a number took a very long time to settle on. There’s a whole history book on the topic!

I listened to an audiobook about the history of zero years ago (can’t remember the name, might be that one). I thought it would be dull enough to fall asleep to.

It was not.

What clocks do you have that say 0, except for the 0 in 10?

... what digital clock goes clockwise?

[-] bdonvr@thelemmy.club 8 points 1 year ago

Well I can tell you that mine definitely doesn't go anti-clockwise

[-] FooBarrington@lemmy.world 3 points 1 year ago

Mine just goes south
