On Sunday April 10Th

[Stargazer]

It was so warm outside when hanging out my washing on April 11th I decided to stretch out on my sun lounger to get some vitamin D and as my skin got warmer and warmer, I removed most of my clothing to get maximin benefit. I got to thinking this: it was less than eleven weeks until June 21st, the longest day of the year and going the other way, would I risk sitting out in full sun last week in August, first week in September. Is the sun stronger and more damaging to skin 11 weeks before or after midsummers day?

Depends on the strength of the sun, not on what day or month it is.
