What is the winter solstice?
The winter solstice marks the shortest day of the year and the official beginning of winter.
The solstice itself is the moment the sun is shining farthest to the south, directly over the Tropic of Capricorn.
This year, the solstice is on Thursday, December 21. The sun will rise in the UK at 08:03 GMT and set at 15:53 GMT, giving just 7 hours and 50 minutes of daylight.
Traditions and rituals
The winter solstice is a major pagan festival, with rituals of rebirth having been celebrated for thousands of years.
Every year revellers gather at Stonehenge to watch the sunrise on the shortest day.
