WINTER SOLSTICE – Day Between December 20 and 23

WINTER SOLSTICE

The Winter Solstice is observed  annually on a day between December 20 and December 23.

According to Wikipedia,  Winter solstice is an astronomical phenomenon which marks the shortest day and the longest night of the year. Winter solstice occurs for the Northern Hemisphere in December and for the Southern Hemisphere in June.

The axial tilt of Earth and gyroscopic effects of the planet’s daily rotation keep the axis of rotation pointed at the same point in the sky. As the Earth follows its orbit around the Sun, the same hemisphere that faced away from the Sun, experiencing winter, will, in half a year, face towards the Sun and experience summer. Because the two hemispheres face opposite directions along the planetary pole, as one polar hemisphere experiences winter, the other experiences summer.

More evident from high latitudes, a hemisphere’s winter solstice occurs on the shortest day and longest night of the year, when the sun’s daily maximum elevation in the sky is the lowest.  The winter solstice itself lasts only a moment in time, so other terms are used for the day on which it occurs, such as “midwinter”, or the “shortest day”. It is often considered the “first day of winter” or the “start of winter” (Lidong in the East Asian calendars), although in meteorology winter spans the entire period of December through February. The seasonal significance of the winter solstice is in the reversal of the gradual lengthening of nights and shortening of days. The earliest sunset and latest sunrise dates differ from winter solstice, however, and these depend on latitude, due to the variation in the solar day throughout the year caused by the Earth’s elliptical orbit (see earliest and latest sunrise and sunset).

Worldwide, interpretation of the event has varied from culture to culture, but many cultures have held a recognition of rebirth, involving holidays, festivals, gatherings, rituals or other celebrations around that time.
