What Is the December Solstice
The December solstice occurs when the North Pole is tilted farthest from the Sun, around December 21 or 22 each year. It marks the beginning of astronomical winter in the northern hemisphere.
Daylight and Darkness Patterns
During the December solstice, the northern hemisphere experiences its shortest day and longest night of the year. Higher latitudes see fewer daylight hours, while areas near the equator remain relatively stable.
Why the Solstice Happens
Earth's axis stays tilted at about 23.5 degrees as it orbits the Sun. This tilt causes sunlight to strike the northern hemisphere at a lower angle, reducing heating and daylight. The opposite occurs in the southern hemisphere, where the December solstice brings the longest day.
