The winter solstice

The winter solstice occurs exactly when the axial tilt of a planet's polar hemisphere is farthest away from the star that it orbits. Earth's maximum axial tilt to our star, the Sun, during a solstice is 23° 26'. More evidently from high latitudes, a hemisphere's winter solstice occurs on the shortest day and longest night of the year, when the sun's daily maximum elevation in the sky is the lowest.[2] Since the winter solstice lasts only a moment in time, other terms are often used for the day on which it occurs, such as midwinter, the longest night or the first day of winter.


The seasonal significance of the winter solstice is in the reversal of the gradual lengthening of nights and shortening of days. Depending on the shift of the calendar, the winter solstice usually occurs on December 21 or 22 each year in the Northern Hemisphere, and June 20 or 21 in the Southern Hemisphere.[3]

Worldwide, interpretation of the event has varied from culture to culture, but most cultures have held a recognition of rebirth, involving holidays, festivals, gatherings, rituals or other celebrations around that time.[4]


The solstice itself may have been a special moment of the annual cycle of the year even during neolithic times. Astronomical events, which during ancient times controlled the mating of animals, sowing of crops and metering of winter reserves between harvests, show how various cultural mythologies and traditions have arisen. This is attested by physical remains in the layouts of late Neolithic and Bronze Age archaeological sites such as Stonehenge in Britain and Newgrange in Ireland. The primary axes of both of these monuments seem to have been carefully aligned on a sight-line pointing to the winter solstice sunrise (Newgrange) and the winter solstice sunset (Stonehenge). Significant in respect of Stonehenge is the fact that the Great Trilithon was erected outwards from the centre of the monument, i.e., its smooth flat face was turned towards the midwinter Sun.[5]

The winter solstice may have been immensely important because communities were not certain of living through the winter, and had to be prepared during the previous nine months. Starvation was common in winter between January and April, also known as the famine months. In temperate climates, the midwinter festival was the last feast celebration, before deep winter began. Most cattle were slaughtered so they would not have to be fed during the winter, so it was almost the only time of year when a supply of fresh meat was available. The majority of wine and beer made during the year was finally fermented and ready for drinking at this time. The concentration of the observances were not always on the day commencing at midnight or at dawn, but the beginning of the pre-Romanized day, which falls on the previous eve.[6]


Since the event is seen as the reversal of the Sun's ebbing presence in the sky, concepts of the birth or rebirth of sun gods have been common and, in cultures using winter solstitially based cyclic calendars, the year as reborn has been celebrated with regard to life-death-rebirth deities or new beginnings such as Hogmanay's redding, a New Year cleaning tradition. In Greek mythology, the gods and goddesses met on the winter and summer solstice, and Hades is permitted to enter Mount Olympus (his domain is the underworld so he of course does not get accepted any other time). Also reversal is yet another usual theme as in Saturnalia's slave and master reversals.

In the northern latitudes, midwinter's day has been an important time for celebration throughout the ages. On this shortest day of the year, the sun is at its lowest and weakest, a pivot point from which the light will grow stronger and brighter. This is the turning point of the year. The romans called it Dies Natalis Invicti Solis, the Birthday of the Unconquered Sun.


The Roman midwinter holiday, Saturnalia, was both a gigantic fair and a festival of the home. Riotous merry-making took place, and the halls of houses were decked with boughs of laurel and evergreen trees. Lamps were kept burning to ward off the spirits of darkness. Schools were closed, the army rested, and no criminals were executed. Friends visited one another, bringing good-luck gifts of fruit, cakes, candles, dolls, jewellery, and incense. Temples were decorated with evergreens symbolizing life's continuity, and processions of people with masked or blackened faces and fantastic hats danced through the streets.

The custom of mummers visiting their neighbours in costume, which is still alive in Newfoundland, is descended from these masked processions.

Roman masters feasted with slaves, who were given the freedom to do and say what they liked (the medieval custom of all the inhabitants of the manor, including servants and lords alike, sitting down together for a great Christmas feast, came from this tradition). A Mock King was appointed to take charge of the revels (the Lord of Misrule of medieval Christmas festivities had his origin here).

In pagan Scandinavia the winter festival was the yule (or juul). Great yule logs were burned, and people drank mead around the bonfires listening to minstrel-poets singing ancient legends. It was believed that the yule log had the magical effect of helping the sun to shine more brightly.

Mistletoe, which was sacred because it mysteriously grew on the most sacred tree, the oak, was ceremoniously cut and a spray given to each family, to be hung in the doorways as good luck. The celtic Druids also regarded mistletoe as sacred. Druid priests cut it from the tree on which it grew with a golden sickle and handed it to the people, calling it All-Heal. To hang it over a doorway or in a room was to offer goodwill to visitors. Kissing under the mistletoe was a pledge of friendship. Mistletoe is still forbidden in most Christian churches because of its Pagan associations, but it has continued to have a special place in home celebrations.

In the third century various dates, from December to April, were celebrated by Christians as Christmas. January 6 was the most favoured day because it was thought to be Jesus' baptismal day (in the Greek Orthodox Church this continues to be the day to celebrate Christmas). Around 350, December 25 was adopted in Rome and gradually almost the entire Christian Church agreed to that date, which coincided with Winter Solstice, the Yule and the Saturnalia. The merry side of Saturnalia was adopted to the observance of Christmas. By 1100 Christmas was the peak celebration of the year for all of Europe. During the 16th century, under the influence of the Reformation, many of the old customs were suppressed and the Church forbade processions, colourful ceremonies, and plays.

In 1647 in England, Parliament passed a law abolishing Christmas altogether. When Charles II came to the throne, many of the customs were revived, but the feasting and merrymaking were now more worldly than religious.
