Northern Hemisphere
In the Northern Hemisphere, the December solstice marks the beginning of winter. Countries like the United States, Canada, Russia, and much of Europe experience their shortest day and longest night.
The winter solstice is a significant astronomical event that marks the shortest day and the longest night of the year. It occurs annually in December in the Northern Hemisphere and in June in the Southern Hemisphere. This event has been observed and celebrated by cultures around the world for thousands of years, often symbolizing rebirth, reflection, and the triumph of light over darkness.
The solstices occur due to the Earth's axial tilt of approximately 23.5 degrees relative to its orbital plane around the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons. During the winter solstice, one hemisphere is tilted the farthest away from the Sun, resulting in the shortest period of daylight.
At the exact moment of the solstice, the Sun reaches its lowest maximum elevation in the sky. In the Northern Hemisphere, this happens around December 21st or 22nd, when the Sun is directly over the Tropic of Capricorn at 23.5 degrees south latitude. In the Southern Hemisphere, the winter solstice occurs around June 20th or 21st, when the Sun is over the Tropic of Cancer at 23.5 degrees north latitude.
In the Northern Hemisphere, the December solstice marks the beginning of winter. Countries like the United States, Canada, Russia, and much of Europe experience their shortest day and longest night.
Conversely, in the Southern Hemisphere, the December solstice signals the start of summer. Nations such as Australia, South Africa, and Argentina enjoy their longest day and shortest night.
The prehistoric monument of Newgrange is aligned with the rising sun on the winter solstice. Built over 5,000 years ago, it predates Stonehenge and the Egyptian pyramids. During the winter solstice, a beam of sunlight illuminates the inner chamber for 17 minutes at dawn, creating a spectacular display that has drawn observers for millennia.
Inti Raymi, the 'Festival of the Sun', is a sacred celebration honoring Inti, the Incan sun god.

The winter solstice is a profound event that connects humanity across time and space. Despite differences in culture and climate, people around the world share common themes in their celebrations—hope, renewal, and the enduring human spirit. Understanding the science behind the solstice enhances our appreciation of these traditions and highlights our connection to the cosmos.
