Summer Solstice - St John's Day
Each day for six months after the winter solstice, the Sun rises a bit higher in the sky. It reaches the maximum height at the summer solstice, the longest day. Evidence of rituals and festivals at the times of the solstices goes back thousands of years.

I would still love to be on the river in one of the valleys in Austria where Sommersonnenwende (summer solstice) is celebrated with lights on the river and on the hills plus fireworks. I found there was a broken link in my article, so have found a new picture of the Wachau Valley on Sommersonnenwende.

But of course the solstice has long past now and we're nearing the equinox.
