Winter solstice

The winter solstice is an astronomical event that occurs when one of the Earth's poles is tilted farthest away from the Sun. This typically occurs around December 21 or 22 in the Northern Hemisphere and around June 20 or 21 in the Southern Hemisphere. During the winter solstice, the Sun travels the shortest path through the sky, resulting in the day with the least amount of daylight and the longest night of the year.
