More evident from high latitudes, a hemisphere's winter solstice occurs on the day with the shortest period of daylight and longest night of the year, when the sun's daily maximum elevation in the sky is at its lowest. Although the winter solstice itself lasts only a moment in time, the term sometimes refers to the day on which it occurs.
When is the shortest day of the year? The shortest day and the longest night of the year in the Northern Hemisphere occur during winter solstice which is usually observed on december 21st or sometimes on december 22nd UTC (see table 1). In 2016 winter solstice is observed on december 21, exactly at 10:44 UTC.
