The Sun's position


The Sun is directly overhead of the Tropic of Capricorn in the Southern Hemisphere during the December Solstice.

The December Solstice occurs when the Sun reaches its most southerly declination of -23.5 degrees. In other words, when the North Pole is tilted furthest – 23.5 degrees – away from the Sun.


2014 Winter Solstice, December Solstice
The Solstice is an astronomical event that happens twice, once in summer and once in winter, each year when the Sun reaches its highest position in the sky as seen from the North or South Pole. During Solstices the tilt of the axil of the Earth (with respect to the Sun) is the maximum at 23° 26'. 

Solstices occur on 20th or 21st June and 21st or 22nd December each year. During summer the day of the solstice is the longest day of the year and during winter the day of the solstice is the shortest day of the year. 

During June it is Summer Solstice in the Northern hemisphere and Winter Solstice in the Southern hemisphere. In other words on June Solstice it is summer time in the UK, the USA, Canada, Russia, India, and China and it is the longest day of the year while it is winter time in Australia, Argentina, Chile, New Zealand and South Africa and it is the shortest day of the year. 

Similarly during December it is Winter Solstice in the Northern hemisphere and Summer Solstice in the Southern hemisphere. In other words during December Solstice it is winter time in the UK, the USA, Canada, Russia, India and China and it is the shortest day of the year while it is summer time in Australia, Argentina, Chile, New Zealand and South Africa and it is the longest day of the year. 

To avoid any confusion Solstices are preferably referred as June Solstice (Northern Solstice) and December Solstice (Southern Solstice). Winter Solstice is also known as Hibernal Solstice. 

In Hindu astrology Winter Solstice is known as Tropical Uttarayana. However Sidereal Uttarayana starts from Makara Sankranti - from this day onwards Devkal starts which is good to start auspicious work.

December solstice and seasons


It is important to note that Earth does not move at a constant speed in its elliptical orbit. Therefore the seasons are not of equal length: the times taken for the sun to move from the vernal equinox to the summer solstice, to the autumnal equinox, to the winter solstice, and back to the vernal equinox are roughly 92.8, 93.6, 89.8 and 89.0 days respectively. The consolation in the northern hemisphere is that spring and summer last longer than autumn and winter (when the December solstice occurs).

The relative position of the Earth's axis to the sun changes during the cycle of seasons. This phenomenon is the reason why the sun’s height above the horizon changes throughout the year. It is also responsible for the seasons through controlling the intensity and duration of sunlight received at various locations around the planet.
