The winter solstice, which this year occurs on December 21 at 4:21 a.m. ET, marks the beginning of astronomical winter in the Northern Hemisphere of the planet.
This event marks the shortest day and the longest night of the year due to the Earth’s position in its orbit around the Sun. On this date, the northern hemisphere is tilted at its farthest point from the Sun, receiving the least amount of sunlight.
The term "solstice" comes from the Latin "sol" (sun) and "sistere" (to stand still), referring to the moment when the Sun appears to pause in its path before changing direction, which does not happen in a literal sense.
In this way, while the Northern Hemisphere prepares for the cold winter, the Southern Hemisphere welcomes summer with long, hot days.
This phenomenon has captured the attention of astronomers for centuries, celebrated in iconic monuments such as Stonehenge in England and Machu Picchu in Peru.
Starting December 22, the days will gradually become longer in the northern hemisphere until the summer solstice in June.
The winter solstice not only marks a seasonal change but also represents a fascinating interaction between the Earth and the Sun.
