|UT date and time of
equinoxes and solstices on Earth
In the Northern Hemisphere this is the Southern solstice, the time at which the Sun is at its southernmost point in the sky, which usually occurs on December 21 to 22 each year. In the Southern Hemisphere this is the Northern solstice, the time at which the Sun is at its northernmost point in the sky, which usually occurs on June 20 to 21 each year.
The axial tilt of Earth and gyroscopic effects of the planet's daily rotation keep the axis of rotation pointed at the same point in the sky. As the Earth follows its orbit around the Sun, the same hemisphere that faced away from the Sun, experiencing winter, will, in half a year, face towards the Sun and experience summer. Since the two hemispheres face opposite directions along the planetary pole, as one polar hemisphere experiences winter, the other experiences summer.
More evident 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. 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", "the shortest day" 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. The earliest sunset and latest sunrise dates differ from winter solstice, however, and these depend on latitude, due to the variation in the solar day throughout the year caused by the Earth's elliptical orbit, see earliest and latest sunrise and sunset.
Worldwide, interpretation of the event has varied from culture to culture, but many cultures have held a recognition of rebirth, involving holidays, festivals, gatherings, rituals or other celebrations around that time.
History and cultural significance 
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.
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.
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. Also reversal is yet another usual theme as in Saturnalia's slave and master reversals.

Direct observation of the solstice by amateurs is difficult because the sun moves too slowly at either solstice to determine its specific day, let alone its instant. Knowledge of when the event occurs has only recently been facilitated to near its instant according to precise astronomical data tracking. It is not possible to detect the actual instant of the solstice (by definition, one can not observe that an object has stopped moving until one makes a second observation in time showing that it has not moved further from the preceding spot, or that it has moved in the opposite direction). Further, to be precise to a single day one must be able to observe a change in azimuth or elevation less than or equal to about 1/60 of the angular diameter of the sun. Observing that it occurred within a two-day period is easier, requiring an observation precision of only about 1/16 of the angular diameter of the sun. Thus, many observations are of the day of the solstice rather than the instant. This is often done by watching the sunrise and sunset or vice versa or using an astronomically aligned instrument that allows a ray of light to cast on a certain point around that time.
Before the scientific revolution many forms of observances, astronomical, symbolic or ritualistic, had evolved according to the beliefs of various cultures, many of which are still practiced today. The following is an alphabetical list of observances believed to be directly linked to the winter solstice.
Beiwe Festival (Sami people of Fennoscandia) 
The Saami, indigenous people of Finland, Sweden and Norway, worship Beiwe, the sun-goddess of fertility and sanity. She travels through the sky in a structure made of reindeer bones with her daughter, Beiwe-Neia, to herald back the greenery on which the reindeer feed. On the winter solstice, her worshipers sacrifice white female animals, and thread the meat onto sticks which they bend into rings and tie with bright ribbons. They also cover their doorposts with butter so Beiwe can eat it and begin her journey once again.
Brumalia (Roman Kingdom) 
Influenced by the Ancient Greek Lenaia festival, Brumalia was an ancient Roman solstice festival honoring Bacchus, generally held for a month and ending December 25. The festival included drinking and merriment. The name is derived from the Latin word bruma, meaning "shortest day" or "winter solstice". The festivities almost always occurred on the night of December 24.
Chawmos (Kalash people of Pakistan) 
In the ancient traditions of the Kalash people of Pakistan, during winter solstice, a demigod returns to collect prayers and deliver them to Dezao, the supreme being. "During this celebrations women and girls are purified by taking ritual baths. The men pour water over their heads while they hold up bread. Then the men and boys are purified with water and must not sit on chairs until evening when goat's blood is sprinkled on their faces. Following this purification, a great festival begins, with singing, dancing, bonfires, and feasting on goat tripe and other delicacies".
Christmas, Natalis Domini (4th century Rome, Christian) 
Christmas or Christ's Mass is one of the most popular Christian celebrations as well as one of the most globally recognized mid-winter celebrations in the Northern Hemisphere. Christmas is the celebration of the birth of Jesus Christ, called the "Son of God," the second person of the Holy Trinity, as well as "Savior of the World." The birth is observed on December 25, which was the Roman winter solstice upon establishment of the Julian Calendar. Activities include feasting, Midnight Masses and singing Christmas carols about the Nativity. Good deeds and gift giving in the tradition of St. Nicholas or Santa Claus is also observed. Many observe the holiday for twelve days leading up to Epiphany.
Deygān, Maidyarem (Zoroastrian, Greater Iran) 
Theologically, Maidyarem is associated with Vahman, the Amesha Spenta (or Holy Immortal) who created the primal bull, and all cattle, and is associated with good plans and intentions. Maidyarem is celebrated in Dey, the tenth month of the Zoroastrian calendar, from the sixteenth (Mihr) to the twentieth (Bahram) day. There are also speculations that by the Persian calendar many celebrated on the last day of the Persian month Azar, the longest night of the year, when the forces of Ahriman are assumed to be at the peak of their strength. The next day, the first day of the month Dey, known as khoram ruz or khore ruz (the day of sun) belongs to God (Ahura Mazda). Since the days are getting longer and the nights shorter, this day marks the victory of Sun over the darkness. The occasion was celebrated in the ancient Persian Deygan Festival dedicated to Ahura Mazda, and Mithra on the first day of the month Dey.
Dongzhi Festival (East Asian Cultural Sphere) 
The Winter Solstice Festival or The Extreme of Winter (Chinese and Japanese: 冬至; Korean: 동지; Vietnamese: Đông chí) (Pinyin: Dōng zhì), (Rōmaji: Tōji), (Romaja:Dongji) is one of the most important festivals celebrated by the Chinese and other East Asians during the dongzhi solar term on or around December 21 when sunshine is weakest and daylight shortest; i.e., on the first day of the dongzhi solar term.
The origins of this festival can be traced back to the yin and yang philosophy of balance and harmony in the cosmos. After this celebration, there will be days with longer daylight hours and therefore an increase in positive energy flowing in. The philosophical significance of this is symbolized by the I Ching hexagram fù (復, "Returning").
Traditionally, the Dongzhi Festival is also a time for the family to get together. One activity that occurs during these get togethers (especially in the southern parts of China and in Chinese communities overseas) is the making and eating of Tangyuan (湯圓, as pronounced in Mandarin Pinyin: Tāng Yuán) or balls of glutinous rice, which symbolize reunion. In Korea, similar balls of glutinous rice (Korean: 새알심) (English pronunciation:Saealsim), is prepared in a traditional porridge made with sweet red bean (Korean: 팥죽) (English pronunciation:Patjook). Patjook was believed to have a special power and sprayed around houses on winter solstice to repel sinister spirits. This practice was based on a traditional folk tale, in which the ghost of a man that used to hate patjook comes haunting innocent villagers on the winter solstice.
Goru (Dogon people of Mali) 
Goru is the (December) Winter solstice ceremony of the Pays Dogon of Mali. It is the last harvest ritual and celebrates the arrival of humanity from the sky god, Amma, via Nommo inside the Aduno Koro, or the "Ark of the World".
Hanukkah (Judaism) 
Hanukkah (Hebrew: חֲנֻכָּה, Tiberian: Ḥănukkāh, nowadays usually spelled חנוכה pronounced [χanuˈka] in Modern Hebrew), also romanized as Chanukah, also known as the Festival of Lights is an eight-day Jewish holiday commemorating the rededication of the Second Temple in Jerusalem at the time of the Maccabean Revolt of the 2nd century BCE. Hanukkah is observed for eight nights, starting on the 25th day of Kislev according to the Hebrew calendar, which may occur at any time from late November to late December in the Gregorian calendar.
The festival is observed by the kindling of the lights of a unique candelabrum, the nine-branched Menorah or Hanukiah, one additional light on each night of the holiday, progressing to eight on the final night. An extra light called a shamash (Hebrew: שמש, "attendant" or "sexton") is also lit each night for the purpose of lighting the others, and is given a distinct location, usually above or below the rest. The shamash symbolically supplies light that may be used.
There is discussion if Hanukkah should be classified as a winter solstice holiday. The Jewish calendar is neither solar nor lunar in nature but exists as a tension between the two. As such, while the events that are commemorated by Hanukkah happened on or around the solstice, because of the use of the lunar calendar, Hanukkah is sometimes celebrated as early as late November.
Hogmanay (Scotland) 
The New Years Eve celebration of Scotland is called Hogmanay. The name derives from the old Scots name for Yule gifts of the Middle Ages. The early Hogmanay celebrations were originally brought to Scotland by the invading and occupying Norse who celebrated a solstitial new year (Britain celebrated the new year on March 25, "Lady Day"). In 1600, with the Scottish application of the January 1 New year and the church's persistent suppression of the solstice celebrations, the holiday traditions moved to December 31. The most widespread Scottish custom is the practice of first-footing which starts immediately after midnight on New Year's Day. This involves being the first person (usually tall and dark haired) to cross the threshold of a friend or neighbour and often involves the giving of symbolic gifts such as salt (less common today), coal, shortbread, whisky, and black bun (a fruit pudding) intended to bring different kinds of luck to the householder. Food and drink (as the gifts, and often Flies cemetery) are then given to the guests.
Traditionally Hogmanay was a day of preparation and the celebrations did not begin until after midnight i.e. into the New Year. It was like many winter festivals and really celebrated the end of winter and the return of the sun.
Inti Raymi (Inca: Peru, Bolivia, Ecuador) 
The Inti Raymi or "Festival of the Sun" was a religious ceremony of the Inca Empire in honor of the sun god Inti. It also marked the winter solstice and a new year in the Andes of the Southern Hemisphere. One ceremony performed by the Inca priests was the tying of the sun. In Machu Picchu there is still a large column of stone called an Intihuatana, meaning "hitching post of the sun" or literally for tying the sun. The ceremony to tie the sun to the stone was to prevent the sun from escaping. The Spanish conquest, never finding Machu Picchu, destroyed all the other intihuatana, extinguishing the sun tying practice. The Catholic Church managed to suppress all Inti festivals and ceremonies by 1572. Since 1944 a theatrical representation of the Inti Raymi has been taking place at Sacsayhuamán (two km from Cusco) on June 24 of each year, attracting thousands of local visitors and tourists. The Monte Alto culture may have also had a similar tradition.
Junkanoo, John Canoe, Dzon'ku 'Nu (West Africa, Bahamas, Jamaica, 19th-century North Carolina, Virginia) 
Junkanoo in The Bahamas, Junkunno or Jonkanoo in Jamaica, is a masquerade, parade and street festival, suspected to be derived from either Dzon'ku 'Nu (tr: Witch-doctor) of the West African Papaws, an Ewe people or Njoku Ji, an Alusi (Igbo: deity) of the Igbo people. It is traditionally performed through the streets towards the end of December, and involves participants dressed in a variety of fanciful costumes, such as the Cow Head, the Hobby Horse, the Wild Indian, and the Devil. The parades are accompanied by bands usually consisting of fifes, drums, and coconut graters used as scrapers, and Jonkanoo songs are also sung. A similar practice was once common in coastal North Carolina, where it was called "John Canoe", "John Koonah", or "John Kooner". John Canoe was likened to the wassailing tradition of medieval Britain. John Canoe was interpreted by many Euro-Americans to bear strong resemblance to the social inversion rituals that marked the ancient Roman celebration of Saturnalia.
Karachun (Ancient West Slavs) 
Karachun, Korochun or Kračún was a Slavic holiday similar to Halloween as a day when the Black God and other evil spirits were most potent. It was celebrated by Slavs on the longest night of the year. On this night, Hors, symbolising the old sun, becomes smaller as the days become shorter in the Northern Hemisphere, and dies on December 22, the December solstice. He is said to be defeated by the dark and evil powers of the Black God. In honour of Hors, the Slavs danced a ritual chain-dance which was called the horo. Traditional chain-dancing in Bulgaria is still called horo. In Russia and Ukraine, it is known as khorovod. On December 23 Hors is resurrected and becomes the new sun, Koleda. On this day, Western Slavs burned fires at cemeteries to keep their departed loved ones warm, organized dinings in the honor of the dead so as they would not suffer from hunger and lit wooden logs at local crossroads.
Koleda, Коляда, Sviatki, Dazh Boh (Ancient East Slavs and Sarmatian) 
In ancient Slavonic cultures, the festival of Koleda began at Winter solstice and lasted for ten days. In Russia, this festival was later applied to Christmas Eve but most of the practices were lost after the Soviet Revolution. Each family made a fire in their hearth and invited their personal household gods to join in the festivities. Children disguise themselves on evenings and nights and as Koledari, visited houses and sang wishes of good luck, like Shchedryk, to hosts. As a reward, they were given little gifts, a tradition called Kolyadovanie, much like the old wassailing or mummers Tradition.
Lá an Dreoilín, Wren day (Celtic, Irish, Welsh, Manx) 
For an unknown period, Lá an Dreoilín or Wren day has been celebrated in Ireland, the Isle of Man and Wales on December 26. Crowds of people, called wrenboys, take to the roads in various parts of Ireland, dressed in motley clothing, wearing masks or straw suits and accompanied by musicians. Previously the practice involved the killing of a wren, and singing songs while carrying the bird from house to house, stopping in for food and merriment.
Lenæa (Ancient Greece and Hellenistic Greece) 
In the Aegean civilizations, the exclusively female midwinter ritual, Lenaea or Lenaia, was the "Festival of the Wild Women". In the forest, a man or bull representing the god Dionysus was torn to pieces and eaten by Maenads. Later in the ritual a baby, representing Dionysus reborn, was presented. Lenaion, the first month of the Delian calendar, derived its name from the festival's name. By classical times, the human sacrifice had been replaced by that of a goat, and the women's role had changed to that of funeral mourners and observers of the birth. Wine miracles were performed by the priests, in which priests would seal water or juice in a room overnight and the next day they would have turned into wine. The miracle was said to have been performed by Dionysus and the Lenaians. By the 5th century BCE the ritual had become a Gamelion festival for theatrical competitions, often held in Athens in the Lenaion theater. The festival influenced the ancient Roman Brumalia.
Lohri (India) 
In Punjab, the winter solstice is celebrated as Lohri. Lohri is of Punjabi folk religion origin It finds no mention in the Hindu Puranas but has over time been twinned with the Hindu festival of Makar Sankranti which is celebrated a day after Lohri and is known as Maghi. For this reason, Lohri is not actually celebrated on the winter solstice but at the end of the month, Paush.
Saint Lucy's Day occurs on December 13, the Winter solstice according to the old (Julian) calendar. A young girl or woman is chosen to portray Lucia wearing a white robe and a red sash representing blood. She wears a crown or wreath with candles (today usually electric ones) and hands out treats to children. She is the one who brings the sun back and chases away winter. The chosen Lucia goes to the homes of the elderly and to hospitals very often, singing songs and glowing with candles. Frequently Lucia celebrations are held at a church where many women and men appear, dressed in white, and sing. However, it is only Lucia who wears the crown while others hold candles and wear tinsel in their hair and around their waists. The boys are dressed as 'Star boys' and wear pointed hats decorated with gold stars.
Lussekatter are often eaten around this time and are commonly made as large buns and sometimes served with coffee, though more commonly with gløgg. The word "lussekatt" ("Lucy cat") may be derived from the great Norse goddess Freya´s carriage drawn by cats. Very often it is the eldest daughter of a family who will wear a white dress and a crown of tinsel or green leaves, and candles. She will give the bread and coffee to her parents, often singing one of many Lucia songs.
Sweden takes this tradition very seriously, even going so far as to allow no male to wear the Lucia crown. Doing so often causes large uproar. It is a large honor to be picked to portray Lucia and many girls want to appear as her attendants in a large group to sing the Lucia songs. The year´s Nobel Prize winners are treated to coffee and "Lucy cats" at their hotel rooms, early in the morning.
Makar Sankranti (Hindu, India and Nepal) 
The Hindu religion has no festival corresponding to the Winter Solstice. However, over time it has become conflated with the astrological festival of Makar Sankranti, which occurs in mid-January.
Maruaroa o Takurua, (Māori people, New Zealand) 
Occurring June 20 – June 22 the Maruaroa o Takurua is seen by the New Zealand Māori people as the middle of the winter season. It follows directly after the rise of Matariki (Pleiades) which marked the beginning of the New Year and was said to be when the Sun turned from his northern journey with his winter-bride Takurua (the star Sirius) and began his journey back to his Summer-bride Hineraumati.
Meán Geimhridh, Celtic Midwinter (Celtic, Ancient Welsh, Neo-druidism) 
Meán Geimhridh (Irish tr: "midwinter") or Grianstad an Gheimhridh (Irish tr: "winter solstice') is a name sometimes used for hypothetical midwinter rituals or celebrations of the Proto-Celtic tribes, Celts, and late Druids. In Ireland's calendars, the solstices and equinoxes all occur at about midpoint in each season. The passage and chamber of Newgrange (Pre-Celtic or possibly Proto-Celtic 3,200 BC), a tomb in Ireland, are illuminated by the winter solstice sunrise. A shaft of sunlight shines through the roof box over the entrance and penetrates the passage to light up the chamber. The dramatic event lasts for 17 minutes at dawn from the 19th to the 23rd of December. "The point of roughness" is the term for the winter solstice in Wales which in ancient Welsh mythology, was when Rhiannon gave birth to the sacred son, Pryderi. Today, among Neo-druids, Alban Arthan (Welsh tr. "light of winter" but derived from Welsh poem, Light of Arthur) is celebrated on the winter solstice with a ritualistic festival, and gift giving to the needy.
Midwinter (Antarctica) 
In research stations throughout Antarctica, Midwinter is celebrated on the Southern Hemisphere winter solstice in June as a way to mark the fact that the people who winter-over just went through half their tour of duty. Depending on the station the celebrations can last from a day to a week and are typically marked by parties, team games, redecoration of the premises and days off work.
Mōdraniht (Anglo-Saxon paganism) 
Mōdraniht (Old English "Night of the Mothers" or "Mothers'-night") was an event held at Christmas Eve by the Anglo-Saxon pagans where a sacrifice may have been made. The event is attested by the medieval English historian Bede in his 8th century Latin work De temporum ratione. Scholars have proposed connections between the Anglo-Saxon Mōdraniht and celebrations involving the dísir, the idisi, and the Matres and Matrones practiced by other Germanic peoples.
Mummer's Day, Montol (Celtic, Cornish people) 
Mummer's Day referencing the animist garbs, or Darkie Day referencing the soot facing ritual, is an ancient Cornish midwinter celebration that occurs every year on December 26 and New Year's Day in Padstow, Cornwall. It was originally part of the pagan heritage of midwinter celebrations that were regularly celebrated all over Cornwall where people would guise dance and disguise themselves by blackening up their faces or wearing masks. In Penzance the festival has been given the name Montol believing it to be the Celtic Cornish word for Winter solstice.
Rozhanitsa Feast (12th century East Slavs, Russia) 
In 12th century Russia, the eastern Slavs worshiped the winter mother goddess, Rozhnitsa, offering bloodless sacrifices like honey, bread and cheese. Bright colored winter embroideries depicting the antlered goddess were made to honor the Feast of Rozhanitsa in late December. And white, deer-shaped cookies were given as lucky gifts. Some Russian women continued the observation of these traditions into the 20th century.
Shab-e Chelleh, یلدا , Yaldā (2nd millennium BC Persian Empire, Iran) 
Derived from a pre-Zoroastrian festival, Shab-e Chelleh is celebrated on the eve of the first day of winter in the Persian calendar, which always falls on the solstice. Yalda is the most important non-new-year Iranian festival in modern-day Iran and it has been long celebrated in Iran by all ethnic/religious groups. According to Iranian mythology, Mithra was born at the end of this night after the long-expected defeat of darkness against light. Shab-e Chelleh is now an important social occasion, when family and friends get together for fun and merriment. Usually families gather at their elders' homes. Different kinds of dried fruits, nuts, seeds and fresh winter fruits are consumed. The presence of dried and fresh fruits is reminiscence of the ancient feasts to celebrate and pray to the deities to ensure the protection of the winter crops. Watermelons, persimmons and pomegranates are traditional symbols of this celebration, all representing the sun. It used to be customary to stay awake Yalda night until sunrise eating, drinking, listening to stories and poems, but this is no longer very common as most people have things to do on the next day.
During the early Roman Empire many Syrian Christians fled from persecution into the Sassanid Empire of Iran, introducing the term Yaldā, meaning "birth", causing Shab-e Yaldā to become synonymous with Shab-e Chelleh. Although both terms are used interchangeably, Chelleh is more commonly accepted for this occasion.
Sanghamitta Day (Buddhism) 
Roman Saturnalia 
Saturnalia was the ancient Roman festival that marked the anniversary (dies natalis, "birthday") of the Temple of Saturn on December 17. It began with a public sacrifice to Saturn and a banquet, followed by private festivities that included gift-giving, continual partying, and a carnival atmosphere that overturned Roman social norms: gambling was permitted, and masters provided table service for their slaves. These festivities eventually expanded through December 23 during the Imperial period.
Macrobius, a Latin writer from late antiquity, explains the holiday at length in his antiquarian work Saturnalia. In one of the interpretations he presents, Saturnalia is a festival of light leading to the winter solstice, with the abundant presence of candles symbolizing the quest for knowledge and truth. The renewal of light and the coming of the new year was celebrated in the later Roman Empire at the Dies Natalis of Sol Invictus, the "Birthday of the Unconquerable Sun," on December 25, the date of the winter solstice in the Julian calendar of the time. The Saturnalia was later subsumed by the Brumalia.
In Greek and Cypriot folklore it was believed that children born during the festival were in danger of turning into Kallikantzaroi which come out of the Earth after the solstice to cause trouble for mortals. Some would leave colanders on their doorsteps to distract them until the sun returned.
Şewy Yelda (Kurdish) 
The Night of Winter. Since the night is the longest in the year, ancient tribes believed that it was the night before a victory of light over darkness and signified a rebirth of the sun. The sun plays an important role in several ancient religions still practiced by some Kurds in addition to its importance in Zoroastrianism.
In modern times, communities in the Kurdistan region still observe the night as a holiday. Many families prepare large feasts for their communities and the children play games and are given sweets in similar fashion to modern-day Halloween practices.
Sol Invictus Festival (3rd century Roman Empire) 
Sol Invictus ("the undefeated Sun") or, more fully, Deus Sol Invictus ("the undefeated sun god") was a religious title that allowed several solar deities, including Elah-Gabal, a Syrian sun god; Sol, the god of Emperor Aurelian; and Mithras, a soldiers' god of Persian origin, to be worshipped collectively. Emperor Elagabalus (218–222) introduced the festival of the birth of the Unconquered Sun (or Dies Natalis Solis Invicti) to be celebrated on December 25, and it reached the height of its popularity under Aurelian, who promoted it as an empire-wide holiday. With the growing popularity of the Christianity, Jesus of Nazareth came to be given much of the recognition previously given to a sun god, thereby including Christ in the tradition.
Soyal (Zuni people and Hopi people of North America) 
Soyalangwul is the winter solstice ceremony of the Zuni and the Hopitu Shinumu, also known as the Hopi. It is held on December 21, the shortest day of the year. The main purpose of the ritual is to ceremonially bring the sun back from its long winter slumber. It also marks the beginning of another cycle of the Wheel of the Year, and is a time for purification. Pahos (prayer sticks) are made prior to the Soyal ceremony, to bless all the community, including their homes, animals, and plants. The kivas (sacred underground ritual chambers) are ritually opened to mark the beginning of the Kachina season.
We Tripantu (Mapuche in southern Chile) 
We Tripantu (Mapudungun tr: new sunrise) is the conclusion of the Mapuche New Year that takes place between June 21 and June 24 in the Gregorian calendar. It is the Mapuche's equivalent to the Inti Raymi. The ancestral incertidubre stayed up throughout the year's longest night with anxiety that the next day would not come. After three days it became clear that the winter was diminishing. The Pachamama (Quechua tr: Mother Earth), Nuke Mapu (uke' Mapu) begins to bloom fertilized by Sol, from the Andean heights to the southern tip. Antu (Pillan), Inti (Aymara), or Rapa (rapanui) Sol, the sun starts to come back to earth, after the longest night of the year: it's winter Solstice. Todo start to bloom again.
Yule (Finnic and Germanic peoples) 
Yule or Yuletide ("Yule-time") is a winter festival that was initially celebrated by the Northern European people as a pagan religious festival, though it was later absorbed into, and equated with, the Christian festival of Christmas. The festival was originally celebrated from late December to early January on a date determined by the lunar Germanic calendar. The festival was placed on December 25 when the Christian calendar (Julian calendar) was adopted. Scholars have connected the celebration to the Wild Hunt.
Terms with an etymological equivalent to Yule are used in the Nordic countries for the Christian Christmas (with its religious rites), but also for other holidays of the season. Yule is also used to a lesser extent in English-speaking countries to refer to Christmas. Customs such as the Yule log, Yule goat, Yule boar, Yule singing, and others stem from Yule. Germanic Neopaganism has adopted the pre-Christian festival, as have some other non-Christian religions, such as Wicca.
Zagmuk, Sacaea (Ancient Mesopotamia, Sumeria, Babylonia) 
Adapting the Egyptian Osiris celebrations, the Babylonians held the annual renewal or new year celebration, the Zagmuk Festival. It lasted 10 days, overlapping either the winter solstice or vernal equinox in its center peak. It was a festival held in observation of the sun god Marduk's battle over darkness. The Babylonians held both land and river parades. Sacaea, as Berossus referred to it, had festivals characterized with a subversion of order leading up to the new year. Masters and slaves interchanged, a mock king was crowned and masquerades clogged the streets. This has been a suggested precursor to the Festival of Kronos, Saturnalia and possibly Purim.
Ziemassvētki (Latvia, Baltic states, Romuva) 
In ancient Latvia, Ziemassvētki, meaning winter festival, was celebrated on December 21 as one of the two most important holidays, the other being Jāņi. Ziemassvētki celebrated the birth of Dievs, the highest god of Latvian mythology. The two weeks before Ziemassvetki are called Veļu laiks, the "season of ghosts."
During the festival, candles were lit for Dieviņš and a fire kept burning until the end, when its extinguishing signaled an end to the unhappiness of the previous year. During the ensuing feast, a space at the table was reserved for Ghosts, who was said to arrive on a sleigh. During the feast, certain foods were always eaten: bread, beans, peas, pork and pig snout and feet. Carolers (Budeļi) went door to door singing songs and eating from many different houses. The holiday was later adapted by Christians in the middle ages. It is now celebrated on December 24, 25 and 26 and largely recognized as both a Christian and secular cultural observance. Lithuanians of the Romuva religion continue to celebrate a variant of the original polytheistic holiday.
