This topic came up at a recent meeting.  The word "main" makes me wonder what the other reasons are.

The main reasons for the earliest sunset to occur in early December and the latest sunrise to occur in January are the fact that Earth's axis is tilted (23.5°) and Earth's orbit around the sun is not a perfect circle shape.
