Charting the latitude at which the sun stops setting

Post date: 2022-06-23 11:53:27

I would like a chart of the latitude at which the sun stops setting (never dipping below the horizon) over time. This seems like it should be pretty easy to find, but I'm having trouble.

This would show 66.56° on the solstice, and a larger number before/after that. I found this, which is quite close but not really what I want, and lots of sites that tell me sunrise/set times for a given location, but none that do the reverse. I would be happy also with a calculator that lets me put in a single day and spits out the latitude at which the sun stops setting.

(I am currently walking north until I catch the sun, and would like to chart my progress)
