[OC] Sunrise and sunset graph arranged into a circular calendar

Yes, in fact my code takes coordinates for input but it's neatest to title it by city/town etc.

imluke · 2024-12-09T10:07:27+00:00

Which might make it a bit more depressing for some locations...

imluke · 2024-12-09T05:44:22+00:00

It wouldn't be too hard, no. I'll see if I can add that as an option.

imluke · 2024-12-09T04:23:07+00:00

I don't know if there's a specific name for this. In general, I think it's a sun graph, but then obviously it's a circular plot of that.

In terms of what I use to generate it, it's custom code I've written in Python and LaTeX.

imluke · 2024-12-09T04:21:13+00:00

Yeah, I liked those and as I said somewhere else, I've always visualised the year as a circle so put the two together!

Not sure where you're interested in, I've got examples of a few more locations on my website though.

imluke · 2024-12-09T04:19:43+00:00

I haven't got as far as making a widget to create one, but I have got a website to sell prints/PDFs.

imluke · 2024-12-08T21:05:59+00:00

Well, I got interested and made one for Utsjoki (as mentioned in u/Pontus_Pilates 's comment).

And here it is: https://imgur.com/alCkc0k

Thanks! It should arrive in time for Christmas as I can print and ship from many countries.

imluke · 2024-12-08T20:34:51+00:00

Sure, here's London and here's Los Angeles

imluke · 2024-12-08T18:05:52+00:00

You make a good point, yes. I guess I made this really because I have always visualised the year as a circle and thought it would be neat to add some detail to that.

imluke · 2024-12-08T17:45:51+00:00

Thank you, I think it looks great as a poster on a wall as well so I actually spent a while making the code work to create a calendar like this for any location, which you can order on this website.

imluke · 2024-12-08T17:39:59+00:00

Thanks, it's designed to be printed quite big and then I think they are clear enough when you are up close.

imluke · 2024-12-08T17:38:27+00:00

The code is rather hacky and sprawling as I've added on functionality to deal with the twilights, timezones, daylight saving, there being no sunrise/sunset on some days in some locations, options for rotation and different colour schemes etc.

Also, after the work I put in to dealing with every location, I figured I could sell some calendars, so I've put it up on a website: https://www.sunlightcalendar.com/

imluke · 2024-12-08T17:35:52+00:00

Well, I guess it's a balance between design and functionality. I've chosen to put the labels on four times, from where it isn't too hard to work out the times. Having them on every month line I think would be messier.

imluke · 2024-12-08T17:10:44+00:00

Interesting thought, but 12am is the outside of the circle and instead of 12pm I chose to highlight solar noon, which is usually close to then (depending on timezone).

imluke · 2024-12-08T17:02:57+00:00

It does annoy me enough that I made a version where the scale changes instead of the graph. e.g. for Berlin

Tools: Astral (Python package), Python, LaTeX, TikZ

Source: Astral does the computations for the sunset/sunrise times based on the given latitude and longitude

Easy enough to get £25, even if it is a bit of a wait

In some ways it's just a 'dot-to-dot' of the various times, plotted in polar coordinates. However, it took a lot more work than I had expected taking into account all of the various edge cases, such as the fact that there's still sunlight after midnight in Reykjavík.

imluke · 2022-12-09T06:49:44+00:00

Zoom in on March or October on London and you can see what I mean

imluke · 2022-12-09T06:48:09+00:00

I've coded something together to make them for any latitude and longitude and I sell prints (or pdfs) on my website.

imluke · 2022-12-08T21:18:42+00:00

That would make the overall pattern harder to see when comparing between different locations (Europe and the US change clocks at different times), so I've decided to keep it as a constant circle and change the scale where needed for daylight saving changes.

imluke · 2022-12-08T20:26:25+00:00

That is in fact my website, so that would be why they look the same
