WINTER SOLSTICE
The solstices are the days when the Sun reaches its farthest northern and southern declinations.

Orbital mechanics require that the length of the seasons be proportional to the areas of the seasonal quadrants, so when the eccentricity is extreme, the seasons on the far side of the orbit can be substantially longer in duration.
