Turns out that "I can see the sun" is not good enough for deciding whether you're able to absorb Vitamin D. I had a deficiency (living in Nordics, not very surprising). So I built a small calculator that calculates during what periods you can absorb Vitamin D from the sun. Very fun to learn about calculating positions of the sun. https://whencanigetvitamind.com |
