By Christmas, you will notice the afternoon sun definitely lasting longer.

The downside for those who have to get up early is that latest sunrise doesn’t occur until about 10 Jan. So those post-New Year commutes make for awfully dark mornings.

This “time-shifting” has nothing to do with the seasons per se. It’s just the orientation of the ellipse happens to make the effect strongest in that portion of the orbit that we call December. “The equation of time.”​​​​​​
