Officially the first day of winter, the winter solstice occurs when the North Pole is tilted 23.5 degrees away from the sun. This is the longest night of the year, meaning that despite the cold winter, the days get progressively longer after the winter solstice until the summer solstice in 2012.
The winter solstice is celebrated by many people around the world as the beginning of the return of the sun, and darkness turning into light. The Talmud recognizes the winter solstice as "Tekufat Tevet." In China, the "Dongzhi" Festival is celebrated on the Winter Solstice by families getting together and eating special festive food.
Until the 16th century, the winter months were a time of famine in northern Europe. Most cattle were slaughtered so that they wouldn't have to be fed during the winter, making the solstice a time when fresh meat was plentiful. Most celebrations of the winter solstice in Europe involved merriment and feasting. In pre-Christian Scandinavia, the Feast of Juul, or Yule, lasted for 12 days celebrating the rebirth of the sun god and giving rise to the custom of burning a Yule log.
In ancient Rome, the winter solstice was celebrated at the Feast of Saturnalia, to honor Saturn, the god of agricultural bounty. Lasting about a week, Saturnalia was characterized by feasting, debauchery and gift-giving. With Emperor Constantine's conversion to Christianity, many of these customs were later absorbed into Christmas celebrations.
One of the most famous celebrations of the winter solstice in the world today takes place in the ancient ruins of Stonehenge, England. Thousands of druids and pagans gather there to chant, dance and sing while waiting to see the spectacular sunrise.
