Can someone explain why the sunrise & sunset are not even @ the solstice ? Also, I noticed that the sunset remains the same time ( 4:12 in my area) until 12/15 while the sunrise continues to get later. I must have fallen asleep when the teacher explained this one

On the subject of "not even at solstice" depends on latitude, that's why the Almanac has a time correction table for sun rise/set. Same reason that on the equinoxes, only the equator gets an equal dose of day/night.

As for the times that seem to "stand still" for a couple of days, I'm not quite sure, but the Earth's path is elliptical so it depends on whether we're on a quick slide or a long smooth portion. The Earth is also on its slip southward from the Tropic of Capricorn in winter to the Tropic of Cancer in summer.

Guess that's why our ancestors made those elaborate moving models of the solar system to get a grip on the various mechanicals involved ... I'm dizzy already! ;-D

Good question, thanks for the topic!
