During this year of immense unpredictably, I have found solace in circumstances that will never change. Our planet, no matter the turmoil we face, will continue to rotate every day while orbiting around our sun annually. Between the 20th and 23rd of December every year, the winter solstice occurs in the northern hemisphere. Also known as the “shortest” day of the year, it is the span of time when our hemisphere receives the least amount of sunlight. This scarcity of light is directly correlated with the tilted axis of our earth’s rotation and its path around the sun.
Ancient and modern cultures alike have celebrated the winter solstice, marking it as the official beginning of the winter season. Past societies that relied on agriculture had to create their own systems of seasonal tracking. Archaeologists have discovered these “observatories” and solar calendars built by ancient civilizations around the globe. Archeoastronomy, the study of how ancient people understood astronomical phenomena, is the term often used to describe these early monuments. Many of these archeoastronomical sites were built to track the solar and lunar cycles. Travel to many of these national sites is not possible this holiday season, but I’ve compiled a list of the structures you can explore, as well as the people that constructed them, with your TLCPL card!
