While temperatures, for the most part, have not reflected it, winter will officially get underway on December 21.

The Winter Solstice, which generally marks the shortest day of the year, occurs in the Northern Hemisphere when the sun reaches its most southerly declination.

Sunrise is estimated for 7:48 a.m. on December 21, while the sun is expected to set as early as 4:44 p.m.

The winter solstice tends to occur on December 21 or December 22 each year, with it rarely occurring on December 20 or 23.

As a matter of fact, the last time a December 23 solstice happened was in 1903, and it is not expected to happen again until 2303.

In the past the Winter Solstice played an important role for many ancient cultures, and various traditions are still observed surrounding the date.
