Two ideas to consider adding to this cool concept:

1. Could there be an option to place 00:00 at the top instead of the bottom? It looks like both positions have been used for analog 24 hour clocks.

https://en.wikipedia.org/wiki/24-hour_analog_dial

2. Could there be an option to set the background to be a polar-projected world map (e.g. United Nations emblem) that rotates to align with the turning of the hour hands?

Another consideration might be to switch 24 to 0 or 00. I've seen a lot of 24 hour clocks that use 24 and I'm not sure why this ever happened since there is no time in hour 24. 12:15 AM/PM is a real thing for a 12-hour clock, but 24:15 isn't, as far as I'm aware. Unless some people consider that to be the very first hour of the day, but that seems like it would invite more confusion.


Tangently related, but working timetables on the London Underground run to 2330, 2345, 2359, but then rather than going to 0000, because the post midnight services (until about 0400) are on the previous date, they then go

2359

2400

2401

And on to 2459, 2500, 2501 etc.

(At least they used to before 24 hour running, not sure about now)


I saw this often in open/close times on bars in Japan in my trip there a couple weeks ago. I saw as high as 28:00


23:59, 1:00:00, 1:00:01 would have been better.


The latter two could be confused with hour:minute:second


24:00 is a real time. See: https://en.wikipedia.org/wiki/24-hour_clock#Midnight_00:00_a...

> there is no time in hour 24

Doesn't matter. 24 marks the end of the day.

One advantage of using 24 instead of 0 is it makes it immediately obvious that this is a 24 hour clock. Otherwise you have to read the 0, see the 23 next to it, and infer that it's 24 hours, which takes a moment if you are not expecting it.


I used to work with a delivery route planning system that had 24:00 as midnight on one day, and 00:00 was midnight on the following day — the same “instant” but on two different days.

I forget the reasoning, but I remember it being described to me as both necessary and a reasonably common construct.


I've just added a setting for midnight to be 0 instead of 24, have a look


> 1. Could there be an option to place 00:00 at the top instead of the bottom?

I wear a 24 hour analogue dial wrist watch, with 24 on top. I'll admit, I sometimes wish I had chosen 12 on top, since it's more naturally to look at the watch during the day, and less so during the night. Since it more naturally follows - on quick visual inspection - what it would look like on a normal 12 hour analogue dial.


There are quite of a few of those about, I have a Vostok 24 hour watch and it's a nice conversational piece.

Rateka also makes a well-regarded 24 hour dial.

Both easily available for €100 or so, though only the vostoks are automatic.


Sounds cool, would you care to link the make/model?


It was the only distributor of 24 hour analogue wrist watches I could find, where the prices were reasonable, is called AAA Watch Club.[0]

Mine is specifically from the Military Time Collection, called Military Dress, I believe.[1] Unfortunately, the specific model appeared to be sold out right now.

Thanks


Great ideas! I've added both! Find them in Settings! Enjoy!


Seems that the World Map is "fixed" and does not rotate to keep it aligned with the hands (expectation is that New York hand should roughly point to New York on the map)?


It rotates on my machine... :(


Could you add the share link? So that if I share the URL with a friend or family,they get exactly my configuration of cities from URL. Maybe the cities can be embedded in URL as GET parameters.


I can add it for sure! It's just a bit more technically involved so maybe next year!


The minute-hand seems to be buggy. It seems to take its 0 as top even though the 0 for hours is at bottom. So when I choose midnight-on-top option, it flips and 00:45 time shows the minute-hand in due-east which is completely wrong.

Would also love to see an option to highlight working hours (9am to 5pm?). Those are important markers for most individuals.


For the second one, that is what is done by this xkcd: https://xkcd.com/1335/

But unfortunately they have noon at the top.
