The Winter Solstice, the point at which we are tilted furthest away from the Sun in Earth's Northern hemisphere, is at 4.19am on Sunday 22 December in 2019.
If you want to catch the fall and rise of the Solstice sun, Sunset on Saturday 21st December is at 3.40pm and sun rise on Sunday December 22nd is at 8.43am according to the UK Hydrographic Office.
The Winter Solstice marks the longest night, or shortest day in the year, and is usually on the 21st December or the day before or after the Solstice - there is very little difference in the amount of daylight hours (like a minute) on these days.
On the plus side, we can look forward to shorter nights and longer days in coming months.
Just as the Winter Solstice marks midwinter on the 21 December, the Summer Solstice, six months hence on the 21 June, marks midsummer.
