Winter Solstice: Shortest Day Of The Year 2023
An important global moment arrives at 10:27 p.m. EST on Thursday, 21 December 2023 when the sun shines above the Tropic of Capricorn in the southern hemisphere.
Winter solstice north of the equator and summer solstice south of it signals the official beginning of a new season.
Astronomically speaking, it’s the beginning of winter in the northern hemisphere and of summer in the southern hemisphere. In the north, it’s the shortest day and the longest night of the year while in the south it's the longest day and the shortest night of the year.
This is all and only a story about how our planet spins. The axis on which Earth rotates is tilted by 23.5 degrees, so during our annual orbit around the sun, different parts of Earth received sunlight for different lengths of time. It was probably caused by an impact billions of years ago.
