This one is New York City, but I actually created a program to make them for anywhere in the world (and have posted a few examples in reply to other comments).

You can check out some examples for a few other places on my website.

So it’s basically website to purchase prints and not to create graphs for my desired locations

Can you make one for Longyearbyen, Svalbard? Would be cool to see what it looks like deep in the Arctic circle.

your website is too hard to navigate to generate a graph, do i have to pay before I actually see the map. I'd not mind paying if I like and decide to get a highdef copy of pdf.
Seems like a subtle plugin for a business.

imluke OP t1_ixuwlmy wrote

I haven't got it set up to generate them on the website (yet), I make each one with a semi-manual process.

I feel there are enough examples on the website that you can get a good idea of what you're getting.

makeCakeNotNuke t1_ixv8fb2 wrote

That makes sense.
My assumption was this was done automatically. Either way you need to get paid if people like your work. But doing it manually makes more sense since you're investing more time to generate. I hoped that was more clearly mentioned in the webapp.

I’m not an expert on web design. But I have experience as a dumb website-user. It took a few reads and clicking around to understand how the whole process works. Maybe have the explanation for the concept in the first page instead of at the bottom of the product description? That’s like a restaurant only letting you know what kind of food they sell after you are already seated.The website itself is beautiful tough, so elegant🤩

Does it account for local daylight saving?

imluke OP t1_ixuotam wrote

Yes, and actually you can choose to show it like this or to have the scale change instead (after all the sun doesn't really change, it's just our clocks).

See the images on the design page of my website to see what I mean.

In the example of NYC op posted you can see dst happening where the graph has a sudden jog and it breaks the smoothness

Moosething t1_ixvyg7g wrote

This is really neat! I've been thinking for a while of creating a visualization like this to explain the consequences of having DST or not for different locations, but never got to it. You almost did all the work for me. The only thing I would personally do is emphasize the 8:00 and 18:00 lines (or something), so it becomes more clear how much daylight we sacrifice and/or gain outside working hours when keeping DST.

That's a lot of winter sunlight and extremely dark for summer time, compared to my reality. Nice graph though :)

itseensasekaantuja t1_ixubvw2 wrote

Heh, I have lived a town that during the summer has only light and during the winter has only darkness. Today that town gets about 3 hours of sunlight. In a few weeks they will start a month long period of no sun at all.

It takes getting used to and if someone comes to experience it during either of the extremes they are visibly confused.

It's a true mindfuck, haha! I'm visiting relatives in northern Norway and it definitely messes with one's head a bit. Normally I live in the middle of Sweden where the changes are quite extreme too, sure, but nowhere near as drastic as above the polar circle

morgulbrut t1_ixyknyv wrote

I've seen the first sunrise after the polar night in Tromsø, it was pretty beautiful.

And one of the weirdest experience was in summer in Rovaniemi, it was already in after midsummer, so at midnight it was twilight, but we could still see where the sun at the horizon. It was in the north. Which is totally explainable but felt a bit off.

itseensasekaantuja t1_ixyoal5 wrote

About 10 years ago I was hiking in the Finnish Lapland during the summer solstice and didn't really bother with the time since the only difference between the day and the night was that it was a bit colder during the night. I actually spent one entire night just hiking since it was nicer to hike with the lower temps.

But at one point I had a pair of Germans arrive at the same campsite where I was, at maybe 1 am in the morning, and they asked what time it was. They'd had trouble getting sleep because it was bright and I think were just amazed at the weirdness of the situation. My theory is that coming from somewhere south into all that could confuse you especially if you kinda rely on your "internal clock" that's tuned to the amount of light. But, if you live all through the transition from the darkest period of the winter all the way to the summer solstice, it actually doesn't seem that out of place.

Blackout curtains are one of those investments that you almost have to do if you cannot adjust to the constant sunlight. Some also purchase those light therapy lamps that artificially create a sense of sunrise in your bedroom. Haven't tried them myself, but I could see those working.

Not sure where you are, but it does vary a lot, here is Edinburgh for example.

nago7650 t1_ixxw3tp wrote

One thing that surprises a lot of people is that New York City (the example show by OP) is actually farther south than Rome, Italy. The majority of the US population lives south of New York City, and the majority of Europe lives north of Rome. To a lot of people in the US, New York City is considered pretty far north and would thus consider the winter months to not have much daylight compared to what they’re used to.

unusedusername42 t1_ixybx5o wrote

Yeah, I've noticed that! Stockholm in southern Sweden is mistakenly perceived as having similar conditions as NY while it's on the 59th northern parallell, meaning Alaska conditions. At this latitude the Sun is visible for 18 hours, 30 minutes during the summer solstice and 6 hours, 11 minutes during the winter solstice. Further up it gets much more extreme. :)

Interesying. What is the program used to create this? And maybe this kind of graphic needs to set fixed equal area for each hour ring.

imluke OP t1_ixu9zlz wrote

My comment isn't showing yet, but I used Python and the Astral package to calculate the sun and moon times, and then it's basically a (complicated) dot to dot between those times.

I was inspired by things like this visualisation which is equal area, but having always visualised the year as a circle I wanted to combine the two.

Should have said, this is for next year (2023). With this year being nearly over it makes sense to start thinking about a calendar for next year.

After a lifetime of city living I moved to the country this year where I can see the sunrise and sunset on the horizon... and the position and movement of the sun and moon day-to-day. It’s terribly interesting.

I have little idea what information you want to convey. No year, no location, no time zone, no hour indication.

It only occurred to me with this graph that daylight saving time is not just half the year!

To be fair, in Belgium it's five months 'winter time' instead of four like the US.

Gareth009 t1_ixxqxhr wrote

I find the visualization quite good. What is the location, and does that matter?

2

Twentydragon t1_ixxxaex wrote

The location does matter. Farther toward the north pole, and you'd have a greater difference between maximum and minimum thicknesses of the sunlight band. At the equator, this would be nearly circular. And in the Southern Hemisphere, the pattern reverses, with longer days near year's end and shorter ones in the middle.

Really goes to show how much the day “shortens” if you maintain your normal schedule after DST, thus lopping off the inside circle for Nov - Mar (assuming you get your day going between 7 and 9am and are not an early riser)

This seems to be about the worst possible way to show this.

It is virtually impossible to see the shape of the curve, and the size of the variation hard to see.

Why choose a circle? It distorts perception.

The area taken from 6 am to noon is nearly half the area from noon to 6 pm. What justifies this design choice from a data visualization perspective?

No_Influence_824 t1_ixwyduk wrote

Rather than a transition from black to white I'd like to see a line showing sunset at a variety of latitudes from the equater to the artic circle. Include the tropic. Maybe sunrise coukd be a different color.

A version in standard time year round would be interesting too.

That's what I was wondering

I figured the middle and rim would both be midnight since that's when a day cycles over and why I asked about 12:01 lol

I was wondering why there is a sudden shift in the time there and shouldn't this close to a circle. And then I remember daylight saving time being a thing...

MeanGreanHare t1_ixy58qm wrote

If anything, time should spring forward in November and fall back in March, so that there's more daylight at the end of winter days.

VVrath69 t1_ixwaour wrote

The writing on the time axis is far too small, and uses the times “12am” and “12pm”, neither of which exist.

Edit to add: Beautiful data is not ambiguous. Midnight and noon are the unambiguous terms you are looking for. 12 noon is the meridiem and can be neither ante nor post itself. 12 midnight is both 12 hours post meridiem and 12 hours ante merdiem.

Of course, all that nonsense could be avoid if the 24-hour clock had been used for the scale instead.

Twentydragon t1_ixxy37y wrote

According to widespread convention, 12 PM is 12:00 (24h). Only the very instant of 12:00:00.0000... is the meridiem; the rest of the minute is post-. Similar applies to 12 AM / midnight / 00:00.

But I definitely agree that 24-hour time is the way to go and obviates this arbitrary half-day-division malarkey altogether.

imluke OP t1_ixu8il5 wrote

I created a circular calendar to show the sunrise and sunset times (as well as the times of the three types of twilight and solar noon) and visualise it in a circle. This one is for New York City.
Inspired by things like this and having always visualised the year as a circle I combined them and personalised it for my location.
I used Python and the Astral package to calculate the sun and moon times.
Having made one for myself, loads of people who saw it suggested I sell it, so I set up a website where you can order a printed custom one of your own: https://sunlightcalendar.com/
