Since the Earth orbits the sun elliptically and therefore a) accelerates and b) has to turn about a degree more than a full circle to bring the sun into the same position, sunrise and sunset are not symmetrical around local noon. Here in Hawaii, the sun set today at 5:45, a minute later than it was setting a few days ago. Of course, it’s still rising later, too, so the total daylight will continue to shorten until the 21st. But the afternoons are getting longer!
