Winter Solstice is the “shortest” day of the year, light wise in the Western Hemisphere. It is also when the winter season begins. Solstices happen twice a year, first around June 21 and then again around December 21. On the June Solstice, the Sun is directly overhead in the Northern Hemisphere, while on the December Solstice, the Sun shines directly overhead in the Southern Hemisphere.
Here is a photo of snow from last year, as we have gotten no snow in this winter season yet.
