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.
Why does this occur? Every year, on December 21 or 22, the planetary tilt means that locations in the northern hemisphere get the shortest duration of sunlight and will experience the shortest day and longest night. On June 21 or 22, they get the longest days and shortest nights. The opposite occurs in the southern hemisphere.
