Winter Solstice: The Shortest Day of the Year

Astronomical Winter Begins

The winter solstice, also known as the hibernal solstice, marks the beginning of astronomical winter in the Northern Hemisphere. It is the day with the shortest period of daylight and the longest night.

Earliest Known Celebration

Evidence suggests that humans may have celebrated the winter solstice as far back as 10,000 years ago. Ancient cultures around the world held festivals and rituals to honor this astronomical event.

Southernmost Sun Path

During the winter solstice, the Earth's North Pole is tilted away from the Sun, causing the Sun's path in the sky to be farthest south in the Northern Hemisphere.

Gradual Day Length Changes

After the winter solstice, days gradually get longer and nights get shorter again, marking the transition from winter to spring.
