This Tuesday, Google decided to celebrate the beginning of the winter season 2021 with a Doodle celebrating the longest night of the year as well as the shortest day, which happens in the upper half of the Earth, the northern hemisphere.
In the Google Doodle for this Tuesday, December 21, you can see a hedgehog walking on snow, a clear reference to the beginning of the winter season and the winter solstice.
The winter solstice, also known as the December solstice, hibernation solstice or hiemal solstice, starts just today and happens when one of the Earth’s poles moves away from the sun at its maximum distance.
As a result, the day is shortened by the reduction of daylight, followed by the longest night of the year, an event that happens every year in December, between the 21st and 22nd, around the world in countries such as the United States, India, United Kingdom, China, Russia and Canada.
In the northern hemisphere, the winter season starts this December 21 and ends on March 20, 2022, three months long.
On this day, with the winter solstice, the sun travels the shortest path, while the day receives the least amount of sunlight and the night is the longest.
Even in certain regions of India dawned with very low temperatures as in its capital, Delhi, registering 4 degrees Celcius, four levels below normal.
