What exactly is the winter solstice?


The December solstice happens at the same instant for all of us, everywhere on Earth. This year the solstice occurs on Wednesday December 21st at 10:44 GMT (Universal time).
The winter solstice happens every year when the Sun reaches its most southerly declination of -23.5 degrees. In other words, when the North Pole is tilted farthest – 23.5 degrees – away from the Sun, delivering the fewest hours of sunlight of the year.

The Sun is directly overhead of the Tropic of Capricorn in the Southern Hemisphere during the December solstice and is closer to the horizon than at any other time in the year, meaning shorter days and longer nights.

The shortest day of the year lasts for 7 hours 49 minutes and 41 seconds in Britain. This day is 8 hours, 49 minutes shorter than on June Solstice. As such, Tuesday December 20th was the longest night of the year with the sun not rising until 08:04 GMT on Wednesday morning.

The day after the winter solstice marks the beginning of lengthening days, leading up to the summer solstice in June.
In the Southern Hemisphere, the opposite is true. Dawn comes early, and dusk comes late. The sun is high and the shortest noontime shadow of the year happens there. In the Southern Hemisphere, people will experience their longest day and shortest night.
