All about the Winter Solstice
While the beginning of summer marks the longest day of the year,
the winter solstice brings the shortest day - and the longest night! - of the year.
The reason for the different seasons is that while the earth rotates around the sun, it also spins on its axis, which is tilted some 23.5 degrees. Because of this tilt, the Northern Hemisphere receives less direct sunlight and the Southern Hemisphere receives more (and vice versa) depending on the season.
Fighting the darkness - winter solstice celebrations in ancient times
In many pre-Christian cultures, December was considered the most dreaded time of year, when the lack of heat and light spelled danger. The cold was stark and the darkness seemed like it would last forever.
So the winter solstice gave rise to many symbols, ancient myths and religious beliefs over the centuries.
To beat the ancient winter blues, Rome celebrated at the feast of Saturnalia.
In pre-christian Britain, the end of December centered around the pagan Yule log in a fiery display to warm the heart during a cold and dreary winter.
With the advent of Christianity, a similar response to winter doldrums was the celebration of Christmas by cultures around the world complete with twinkling lights, holiday feasts & lively festivals.
