Winter solstice marks the shortest day of the year in the UK when we have the fewest hours of daylight.
The winter solstice takes place when the Earth’s Northern Hemisphere is tilted furthest away from the sun.
Conversely, on the summer solstice, which usually falls on June 21, the opposite effect takes place and we get our longest day of the year.
After December 21, the nights will get shorter and we’ll have more daylight hours as the Earth rotates towards the sun again.
The sunrise was at 8.26am and it is due to set at 3.50pm.
That gives us a day length of seven hours, 24 minutes and 18 seconds today (Tuesday, December 21) – five seconds shorter than Monday (December 20).
Those further to the north will have a shorter day, with Edinburgh seeing just six hours and 58 minutes of daylight.
