Winter Solstice: The Shortest Day of The Year

Il giorno più corto dell’anno viene festeggiato in tutte le culture e in molti modi diversi, come il Natale. Si tratta, in realtà, di un fenomeno astronomico attorno al quale i popoli antichi crearono rituali destinati a scacciare l’oscurità. Molti di questi sopravvissero venendo incorporati nelle festività moderne.

The 21st of December is the winter solstice. On this day, the northern hemisphere has the fewest daylight hours of the year. The day lasts just under eight hours, and as such it is the shortest day and the longest night of the year. By contrast, during the summer solstice, daylight lasts up to sixteen hours, while during the spring and autumn equinoxes, the days and nights both last around twelve hours.

The Earth is tilted on its axis, so the Sun moves higher or lower across the horizon throughout the year. During the winter solstice, the North Pole is pointed furthest away from the Sun. It also means it is the coldest time of the year. In the southern hemisphere, the South Pole points towards the Sun, so the conditions are opposite. Down Under, in Australia, in the southern hemisphere, it is the hottest time of the year.

from pagan to christian

While today this simple scientific explanation satisfies most people, in ancient times the darkening days frightened people. In Britain, druids burnt logs to banish the darkness and evil spirits. The Norsemen of Scandinavia celebrated the festival of Juul or Yule. Ancient Romans held Saturnalia, a wild festival of rebirth. Work stopped and rules were temporarily suspended. People decorated their houses, lit candles and exchanged gifts.

Elements of these pagan rituals were integrated into the Christian celebration of Christmas. When the Julian calendar replaced the Gregorian calendar, the winter solstice moved from the 25th to the 21st of December. However, Christmas remained on the 25th.

The winter solstice coincides with festivals all around the world. In China, Dong Zhi heralds the return of longer days with ancestral worship, rice wine making and recitals. In Iran, Shab-e Yalda celebrates the Sun god Mithra’s victory over darkness, with food, drink and poetry. In Japan, Toji traditions include taking yuzu baths and eating pumpkins.

Modern pagans continue to celebrate the winter solstice. The most important site is Stonehenge in southwest England. The original builders of Stonehenge did not understand the reason for the Sun’s changing movements, but they were able to calculate them with absolute precision. On the shortest day, the Sun’s rays move in perfect alignment with the stones, and the Sun finally sets through the Great Trilithon, the tallest of the stones. Some 5,500 years on, people still gather here to witness this awe-inspiring event.
