Despite the predictions to the contrary, both the first day of winter and the shortest day of the year will happen today at 11:12 UTC, the morning of the winter solstice.  The word solstice is relatively old in English, dating back to the 13th century.  Solstice derives from the Latin word solstitium meaning very literally the point at which the sun stands still, a combination of the words sol meaning sun and the past participial stem of sistere meaning to come to a stop, make stand still.  Celebrated thoughout history as either a secular or religious day, the solstice marks the point on the ecliptic when the Northern Hemisphere is pointed most away from the sun and therefore has the shortest day.  Technically if the Mayans are correct and the world ends today, it really will be not only the shortest day of the year but the shortest day of all time.  Look for my post on that tomorrow.
