Winter solstice occurs today

The longest night in Turkey falls on December 21, known as the winter solstice. The winter solstice represents the day when the Sun reaches the Southern Hemisphere and descends to its lowest point in the Northern Hemisphere. On December 21, the night lasts for the longest duration across Turkey. However, the length of the night on these dates may vary slightly depending on geographical location and climatic conditions.

Why December 21?

December 21 represents the winter solstice of the year in the northern hemisphere. In the Northern Hemisphere, this date is the day when the Sun reaches its lowest point and the night duration is at its longest. This situation is caused by the tilt of the Earth's axis. As the Earth rotates around its axis at a tilted angle, this tilt is known for its effects on seasons and day lengths.

The winter solstice represents the moment when the Sun reaches directly to the Southern Hemisphere and descends to its lowest point in the Northern Hemisphere. This situation causes days to be shorter and nights to be longer during the winter months in regions at northern latitudes. Since sunlight does not reach northern latitudes at a steeper angle, the light does not spread over a wider area, which leads to shorter days. Therefore, December 21 represents the longest night and the shortest day in northern latitudes.
