Astronomical winter, the shortest day of the year, begins on December 21st. The sun rises at 7:27 and sets at 15:55, so it will be a bright day of barely eight and a half hours.
Starting today, the period of light will increase slowly but gradually until spring equals between day and night, March 20, when we will have brighter hours of darkness until June 20. Google also remembers the event with a winter version of a hedgehog doodle instead of its logo. (The search giant greeted fall with this, too.)
In winter coup At that time, that is, today, the Earth’s rotation axis is tilted at the greatest angle to the sun’s rays. The dynamics of the day and nights and the periodic changes in the seasons also come from the position of our planet in relation to the Sun. On the day of the winter solstice, the northern hemisphere is farthest from the sun, and at the moment of the solstice, the axis of rotation of the Earth deviates at the greatest angle from the sun’s rays. It is scheduled to take place on December 21 at 5 p.m.
At the North Pole, the sun does not rise at this time, in the south it revolves around a constant height throughout the day. The situation is similar in the arctic circles, in the north it is the only day when we cannot see our star, but in the south of the arctic it remains in the sky for more than 27 hours.
