Vitamin D today

Is there vitamin D in Berlin today?

In Berlin the UV index does not reach 3 at any point today, and below that minimum the skin makes no vitamin D however long the exposure lasts. What decides it is not how high the sun gets but how much UVB reaches the ground: with the sun this oblique, the ozone layer absorbs nearly all of it.

Vitamin D window: None today
In the sun, at the best moment: —
Sunrise: 07:24
Sunset: 18:22

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 Berlin, 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.
