It would be fun to see this with local daylight hours mapped to the squares, so I could get a feel for where my consumption is at within "daylight" vs the whole "day"

SunCalc is a good tool for this, if you're interested: https://github.com/mourner/suncalc

(I've used it on a personal project, and the API was a little awkward but the results are good: https://daylight.website/)

That's interesting - didn't cross my mind! Thanks for the pointer.

Btw, the website you linked doesn't work for me. I get the "Uncaught (in promise) TypeError: navigator.geolocation is undefined" on Firefox 98.0.2 on macOS 12.3.1

Your privacy settings / extensions are blocking geolocation

Your personal project is a pretty cool and interesting way to visualize daylight (especially using the fast forward button to go through a week at a time). Thanks for making it.

Thank you, I'm glad you enjoyed it. I love the week skip too, interesting to see the shape change over the year.

Undocumented feature: if you hold down "w" or "shift+w" keys you can skip through weeks even faster.

I love your personal project! Would make an amazing smartwatch face!

There's an Apple watch face called "solar dial" that's pretty similar, and I've seen others like this.

To me this is the most logical watch face — everything else just confuses matters.

Oo, this does watch face does look nice https://www.hodinkee.com/articles/the-eerie-beauty-of-the-ap...

Funnily enough I had that article already saved to pinboard!

Love your app btw, I made a similar clock years ago but with just sunrise and sunset times. I've just updated it with suncalc.js to add twilight times also, so thanks.

Most hackers are active outside of this time range.

Agreed, but still useful IMHO to get a sense of "where" you are in the day.

very cool project!
