Winter Solstice on December 21st: the longest night of the year. The shortest day of the year, the longest night occurs today, Sunday, December 21st. The so-called Winter solstice is an astronomical phenomenon that occurs in the North Hemisphere when the Earth North axis is at the longest distance to the sun.
When is the longest day of the year? The longest day and the shortest night of the year in the Northern Hemisphere occur during summer solstice which is usually observed on june 21st or sometimes on june 20 UTC (see table 1). In 2016 summer solstice is observed on june 20th, exactly at 22:34 UTC. This is also the day of the shortest day and the longest night in the Southern Hemisphere. The opposite case takes place during december solstice - the shortest day and the longest night occur in the Northern Hemisphere and the longest day and the shortest night are observed in the Southern Hemisphere.
