I noticed yesterday that sunset is now occurring at 4:12pm. The day before it was 4:11pm. So sunset is getting later! Summer is almost here, right?
p.s. Before some smart-alec points it out, yes I know that sunrise is still getting later so the number of daylight hours are still shrinking.
It is left as an exercise to the reader to explain why the two events do not occur on the same day - in other words, sunset starts getting later several weeks before sunrise starts getting earlier. Note: the explanation is very complicated.
