Hello,
Although the times of the latest sunset and as well the earliest
sunrise do not occur on the Summer Solstice, there is variability in
their respective dates which depends on latitude. At the equator, where
the rate at which the length of the day increases and decreases is much
smaller, the latest sunset is around July 25! I believe in your example
the latitude must be roughly around 50dN for the latest sunset to occur
around June 25 and where the earliest sunrise would have been somewhere
around June 17. Where I'm at, lat 36.5dN, the latest sunset will be
around June 27.
Regards (and much admiration),
Luke Coletti
