Science of the Winter Solstice

As I’ve mentioned before, the Romans celebrated a holiday known as the Saturnalia beginning on the Winter Solstice. The word Solstice comes from the Latin “solstitium” meaning “Sun, standing still.” This year it occurs on December 21 at 10:03 GMT (or UTC) and marks the first day of the Winter season in the Northern Hemisphere from an astronomical perspective.
