There is a way to stay current on the all the astronomical adjustments needed to appreciate summertime fun at the Summer Solstice News page.
I know it's summer because it's hot and humid and the NBA finals just ended.
Before there were NBA finals in June (which began in June 1976 - yay Celtics), humans huddled around the giant rocks at Stonehenge (when Celtics meant something rather different).
Many humans still gather on the spot today (see image below from the BBC). Yay humans.
Yay astronomy and yay daylight for a long long time today. Yay.
