If you read this from my email link, by the time you get to it on Monday morning, astronomical winter will have begun. The official time of the winter solstice is 5:02 am EST, and tomorrow will be the shortest day of 2020. Of course, climatological winter began on December 1, so we are already partway through the season according to my climatology friends. You can read more about the winter solstice at EarthSky here.
