“The 2016 December solstice will come on the 21st at 10:44 UTC. That’s 4:44 a.m. on December 21, for those in the central time zone in North America. It’s when the sun reaches its southernmost point for the year. This solstice marks the beginning of the winter season in the Northern Hemisphere, and the start of the summer season in the Southern Hemisphere. And, no matter where you are on Earth, it marks the beginning of your shortest season.” http://earthsky.org/tonight/years-shortest-season-starts-with-december-solstice
Best wishes for a happy and healthy winter or summer season wherever you are on Earth!
