During winter at latitudes above ~35 degrees, the sun's angle is too low for UVB rays to penetrate the atmosphere effectively. This means little to no Vitamin D can be produced from sun exposure. Our calculator warns you if you are in a 'Vitamin D Winter' zone.
Our calculator provides a 'Safe Exposure Time' which is an estimate of how long you can stay in the sun before the risk of sunburn increases. It's a conservative estimate to promote sun safety.
