Why is the earliest sunset not on the solstice?

Mostly because of Earth's orbital eccentricity. Seriously. https://en.wikipedia.org/wiki/Equation_of_time

Interesting I just looked up that the sun does set at the earliest time at 4:45pm on Dec 7 with a sun rise at 7:13am in DC. The shortest day is the 21st like we all know but the sun rise happens at 7:23am with a sun set at 4:49pm.

The Equation of Time apparently. Solstice is just the shortest day, not necessarily the earliest sunset.

Winter Solstice is the shortest day, and also when the sun appears to reach an endpoint in its analemma.
