Vitamin D today

Is there vitamin D in Copenhagen today?

In Copenhagen the skin makes vitamin D while the UV index reaches 3: today that runs from 12:00 to 16:00. At the best moment about 14 minutes with an average skin type and a quarter of the body uncovered is enough for roughly 1000 IU.

Clear-sky figures: cloud lowers the UV index and lengthens the time needed.

Why tomorrow is not the same

The window moves with the height of the sun, which changes every day, and with the ozone column over Copenhagen, which varies with the season. It is not one fixed fact about the city: it runs much longer in some months than in others, and at high enough latitudes there are months when it never opens.
