Subtleties of the Solstice
From The winter of our solsticular discontent
The winter solstice marks the longest night and shortest day of the year. However, it’s not when the Sun rises latest and sets earliest! The Earth has the unfortunate habit of orbiting the Sun in an ellipse, which screws things up a bit when it comes to timing.
Plugging Minneapolis into the Sun or Moon Rise/Set Table for One Year: U.S. Cities and Towns shows that sunrise is going to continue getting later for another couple weeks, while we are well past the earliest sunset. Hence I have been seeing a little more daylight when I get off my bus home in the evening.
