As the chill sets in and daylight wanes, winter appears to be upon us. However, the official start of winter in the Northern Hemisphere won’t arrive until December 21, 2025, known as the winter solstice. This event marks the shortest day and longest night of the year, while in the Southern Hemisphere, residents will be basking in summer during their longest day and shortest night.
The transition between seasons is a result of Earth’s journey around the Sun, coupled with the tilt of its axis at an angle of 23.5 degrees. During the December solstice, the Northern Hemisphere is tilted away from the Sun, leading to reduced sunlight and the onset of winter. Conversely, the Southern Hemisphere, tilted toward the Sun, enjoys longer days and warmer weather.
Historically, the winter solstice has held significant importance for various ancient cultures. Their understanding that after the solstice, days would gradually grow longer brought a sense of hope amid the harsh winter months. Celebrations were often elaborate, and many civilizations constructed structures to align with the Sun’s path.
One of the most renowned sites is Stonehenge in Wiltshire, England, where people gather annually to witness the breathtaking sunrise as it aligns perfectly with the stones. Another notable site is Newgrange in Ireland’s Boyne Valley, a 5,000-year-old mound that illuminates its central chamber with sunlight at dawn on the winter solstice—a mesmerizing event that lasts for just 17 minutes.
Modern celebrations of the winter solstice continue in various forms across the globe. In Japan, people take soothing yuzu baths, believed to improve health and ward off winter ailments. Meanwhile, in Norway, towns light bonfires to honor the occasion, and Sweden embraces the spirit with candlelit processions.
As we approach this astronomical event, it serves as a reminder to celebrate the natural cycles of our planet and the connections we share through the changing seasons. Happy Winter Solstice!
