THE shortest day of the year marks the changing of the seasons and takes place this year on December 21 (2020).
Also known as the winter solstice, the shortest day occurs each year when the sun is at it's lowest point in the sky. But what time will the sun set on this day?
What time is sunset on the shortest day of the year 2020?
This year’s winter solstice – the point where the sun is lowest in the sky – will take place on Monday 21 December.
The exact moment sunrise occurs will take place around 10.02am according to the Royal Museum Greenwich website.
In the Northern Hemisphere, in London the sun will set at approximately 15:53.
The winter solstice marks the end of autumn and the advent of winter.
But solstice will now mark the gradual increase of daylight and shorter nights.
Why is it called the shortest day of the year?
The shortest day of the year in the northern hemisphere always occurs in December.
But its timing varies as each year passes.
This is because there are 365.25 days in our calendar year, or how long it takes for the earth to orbit the sun.
It means the exact time the sun is lowest in the sky shifts approximately six hours each year.
We also skip a day every four years – known as a leap year – which adjusts the timings.
Last year the shortest day was on 22 December – but as 2020 is a leap year, the date of winter solstice shifts back 24 hours.
How many daylight hours are there on shortest day of 2020?
The number of daylight hours on the shortest day is, of course, shorter than other days of the year.
On December 21 2020, there is 7 hours, 49 minutes and 42 seconds of daylight.
The shortest day is some 8 hours, 48 minutes and 38 seconds shorter than the summer solstice – the longest day of the year when daylight hours are at a maximum.
