Understanding the Science Behind the Winter Solstice Celebration
Written on
Chapter 1: The Significance of the Winter Solstice
The Romans observed a festival known as Saturnalia that commenced on the Winter Solstice. The term "Solstice" originates from the Latin word “solstitium,” which translates to “Sun, standing still.” In 2024, this astronomical event will take place on December 21 at 10:03 GMT (or UTC), marking the onset of winter in the Northern Hemisphere.
The Earth's seasons result from its tilt of approximately 23 degrees and 27 minutes relative to its orbital plane. This tilt causes the planet to rotate like a tilted top. The Winter Solstice represents the day with the least sunlight, as the Sun reaches its lowest point in the sky, particularly noticeable in the Northern Hemisphere. The farther you are from the Equator, the more evident this phenomenon becomes during winter. However, as the Earth continues its orbit, the hemisphere tilted towards the Sun shifts, leading to reversed seasons.

In the Northern Hemisphere, the Sun appears at its lowest elevation in the sky, maintaining a consistent height around noon for several days before and after the solstice. This optical illusion gives the impression that the Sun is "standing still." Following the Winter Solstice, the days gradually begin to lengthen while the nights shorten.
Subsection 1.1.1: The Ancient Roman Celebration of Saturnalia
Previously, I discussed how the ancient Romans commemorated Saturnalia around this time, paying tribute to the chief deity at the Temple of Saturn in the Roman Forum. Some customs from these ancient celebrations can still be observed today, particularly around this season. Additionally, the name "Saturday" is derived from Saturn.
Section 1.2: Fun Facts About the Winter Solstice
Commonly referred to as the “shortest day of the year” or the “extreme of winter,” the Winter Solstice marks the official start of the winter season. Notably, it is the day when shadows cast at noon are the longest. Here are some fascinating statistics:
- New York City: 9 hours, 15 minutes of sunlight
- Helsinki, Finland: 5 hours, 49 minutes of sunlight
- Barrow, Alaska: 0 minutes of sunlight — no sunrise until January 22
