Is the longest day adjacent to the shortest night?
I’m not sure what he means by his explanation, but he’s not totally off to think there would at least be a possibility of the longest ‘day’ not being adjacent to the shortest ‘night’. As measured from the Sun’s local zenith to the next local zenith, solar days are not the same length of time (24 hours is just the average amount of time to get from noon to noon). It takes longer to get from local noon to the next local noon at the solstices when the Earth is tilted directly toward or directly away from the Sun. The shortest solar days (noon to noon) should be at the equinoxes. (In other words, if there are more total seconds in the solar day at the solstice, then having the most daylight seconds doesn’t necessarily mean having the shortest night time seconds). Additionally, the Earth’s orbit is slightly elliptical. At perihelion (closest point to the Sun), the Earth is traveling faster and sweeping out a bigger angle per second. That means the Earth has to rotate further to get back to
