Samhain
Samhain (;  ) is a Gaelic festival marking the end of the harvest season and the beginning of winter or the "darker half" of the year. Traditionally, it is celebrated from 31 October to 1 November, as the Celtic day began and ended at sunset. This is about halfway between the autumn equinox and the winter solstice. It is one of the four Gaelic seasonal festivals, along with Imbolc, Bealtaine and Lughnasadh. Historically, it was widely observed throughout Ireland, Scotland and the Isle of Man. Similar festivals are held at the same time of year in other Celtic lands, for example the Brittonic Calan Gaeaf (in Wales), Kalan Gwav (in Cornwall), and Kalan Goañv (in Brittany).

Samhain is believed to have Celtic pagan origins and there is evidence it has been an important date since ancient times. Some Neolithic passage tombs in Ireland are aligned with the sunrise around the time of Samhain. It is mentioned in some of the earliest Irish literature and many important events in Irish mythology happen or begin on Samhain. It was the time when cattle were brought back down from the summer pastures and when livestock were slaughtered for the winter.

As at Bealtaine, special bonfires were lit, which were deemed to have protective and cleansing powers, and there were rituals involving them. Like Bealtaine, Samhain was seen as a liminal time, when the boundary between this world and the Otherworld could more easily be crossed. This meant the Aos Sí, the 'spirits' or 'fairies', could more easily come into our world. Most scholars see the Aos Sí as remnants of the pagan gods and nature spirits. At Samhain, it was believed that the Aos Sí needed to be propitiated to ensure that the people and their livestock survived the winter. Offerings of food and drink were left outside for them. The souls of the dead were also thought to revisit their homes seeking hospitality. Feasts were had, at which the souls of dead kin were beckoned to attend and a place set at the table for them.

Mumming and guising were part of the festival, and involved people going door-to-door in costume (or in disguise), often reciting verses in exchange for food. The costumes may have been a way of imitating, and disguising oneself from, the Aos Sí. Divination rituals and games were also a big part of the festival and often involved nuts and apples. In the late 19th century, Sir John Rhys and Sir James Frazer suggested that it was the "Celtic New Year", and this view has been repeated by some other scholars.

In the 9th century, the Western Christian church shifted the date of All Saints' Day to 1 November, while 2 November later became All Souls' Day. Over time, Samhain and All Saints'/All Souls' merged to create the modern Halloween. Historians have used the name 'Samhain' to refer to Gaelic 'Halloween' customs up until the 19th century.

Since the later 20th century, Celtic neopagans and Wiccans have observed Samhain, or something based on it, as a religious holiday. Neopagans in the Southern Hemisphere often celebrate Samhain at the other end of the year (about 1 May).

Etymology
In Modern Irish as well as Scottish Gaelic the name is . Older forms of the word include the Scottish Gaelic spellings  and . In Manx Gaelic the name is . 

These are also the names of November in each language, shortened from Mí na Samhna (Irish), Mì na Samhna (Scottish Gaelic) and Mee Houney (Manx), meaning "month of Samhain". The night of 31 October—Halloween—is Oíche Shamhna (Irish), Oidhche Shamhna (Scottish Gaelic) and Oie Houney (Manx), meaning "Samhain night". The day of 1 November, or the whole festival, may be called Lá Samhna (Irish), Là Samhna (Scottish Gaelic) and Laa Houney (Manx), meaning "Samhain day".

These names all come from the Old Irish Samain or Samuin , the name for the festival held on 1 November in medieval Ireland. This comes from Proto-Indo-European *semo- ("summer"). One suggestion is that the name means "summer's end", from sam ("summer") and fuin ("end"), but this may be a folk etymology. In 1907, Whitley Stokes suggested an etymology from Proto-Celtic *samani ("assembly"), and Joseph Vendryes suggested that it is unrelated to *semo- ("summer"), because the Celtic summer ended in August.

Coligny calendar

The Gaulish month name SAMON[IOS] "(pertaining to) Summer" on the Coligny calendar is likely related to the word Samhain. A festival of some kind may have been held during the 'three nights of Samonios (Gaulish trinux[tion] samo[nii]). The Gaulish calendar seems to have split the year into two-halves: the first beginning with the month SAMON[IOS] and the second beginning with the month GIAMONIOS, which is related to the word for winter, PIE *g'hei-men- (Latin hiems, Latvian ziema, Lithuanian žiema, Slavic zima, Greek kheimon, Hittite gimmanza), cf. Old Irish gem-adaig ('winter's night'). Samonios may represent the beginning of the summer season and Giamonios (the seventh month) the beginning of the winter season. The lunations marking the middle of each half-year may also have been marked by festivals.

History
Samain or Samuin was the name of the feis or festival marking the beginning of winter in Gaelic Ireland. It is attested in some of the earliest Old Irish literature, from the 10th century onward. It was one of four Gaelic seasonal festivals: Samhain (~1 November), Imbolc (~1 February), Bealtaine (~1 May) and Lughnasadh (~1 August). Samhain and Bealtaine, at opposite sides of the year, are thought to have been the most important. Sir James George Frazer wrote in The Golden Bough: A Study in Magic and Religion that 1 May and 1 November are of little importance to European crop-growers, but of great importance to herdsmen. It is at the beginning of summer that cattle are driven to the upland summer pastures and the beginning of winter that they are led back. Thus, Frazer suggests that halving the year at 1 May and 1 November dates from a time when the Celts were mainly a pastoral people, dependent on their herds. 

Some Neolithic passage tombs in Ireland are aligned with the sunrise around the times of Samhain and Imbolc. These include the Mound of the Hostages (Dumha na nGiall) at the Hill of Tara, and Cairn L at Slieve na Calliagh.

In medieval Ireland the festival marked the end of the season for trade and warfare and was a time for tribal gatherings. These gatherings are a popular setting for early Irish tales.

In Irish mythology

Irish mythology was originally a spoken tradition, but much of it was eventually written down in the Middle Ages by Christian monks, who Christianized it to some extent. Nevertheless, these tales may shed some light on what Samhain meant and how it was marked in ancient Ireland.

Irish mythology says that Samhain was one of the four seasonal festivals of the year, and the 10th-century tale Tochmarc Emire ('The Wooing of Emer') lists Samhain as the first of these four "quarter days". The tales say it was marked by great gatherings where they held meetings, feasted, drank alcohol, and held contests. Specifically, Samhain is described as the Easter festival of the Pagans when every seven years the Feast of Tara was held, during which new laws and duties were ordained and Ireland's councils were formed; anyone who broke the laws established during this time would be banished. The High King also appointed 150 champions to enforce his rule, laws, and hunting and appointed a steward over all of Ireland. The other important holidays and their festivals compared to Samhain are the Fair of Tailtiu on Lughnasadh and the Great Meeting of Uisneach on Beltane.

According to Irish mythology, Samhain (like Bealtaine) was a time when the 'doorways' to the Otherworld opened, allowing supernatural beings and the souls of the dead to come into our world; but while Bealtaine was a summer festival for the living, Samhain "was essentially a festival for the dead". The Boyhood Deeds of Fionn says that the sídhe (fairy mounds or portals to the Otherworld) "were always open at Samhain". It tells us that the High King of Ireland hosted a great gathering at Tara each Samhain. Each year the fire-breather Aillen emerges from the Otherworld and burns down the palace of Tara after lulling everyone to sleep with his music.

One Samhain, the young Fionn mac Cumhaill is able to stay awake and slays Aillen with a magical spear, for which he is made leader of the fianna. In a similar tale, one Samhain the Otherworld being Cúldubh comes out of the burial mound on Slievenamon and snatches a roast pig. Fionn kills Cúldubh with a spear throw as he re-enters the mound. Fionn's thumb is caught between the door and the post as it shuts, and he puts it in his mouth to ease the pain. As his thumb had been inside the Otherworld, Fionn is bestowed with great wisdom. This may refer to gaining knowledge from the ancestors. Acallam na Senórach ('Colloquy of the Elders') tells how three female werewolves emerge from the cave of Cruachan (an Otherworld portal) each Samhain and kill livestock. When Cas Corach plays his harp, they take on human form, and the fianna warrior Caílte then slays them with a spear.

Some tales may suggest that offerings or sacrifices were made at Samhain. In the Lebor Gabála Érenn (or 'Book of Invasions'), each Samhain the people of Nemed had to give two-thirds of their children, their corn and their milk to the monstrous Fomorians. The Fomorians seem to represent the harmful or destructive powers of nature; personifications of chaos, darkness, death, blight and drought.Smyth, Daragh. A Guide to Irish Mythology. Irish Academic Press, 1996. p. 74 This tribute paid by Nemed's people may represent a "sacrifice offered at the beginning of winter, when the powers of darkness and blight are in the ascendant". According to the later Dindsenchas and the Annals of the Four Masters—which were written by Christian monks—Samhain in ancient Ireland was associated with a god or idol called Crom Cruach. The texts claim that a first-born child would be sacrificed at the stone idol of Crom Cruach in Magh Slécht. They say that King Tigernmas, and three-fourths of his people, died while worshiping Crom Cruach there one Samhain. 

The legendary kings Diarmait mac Cerbaill and Muirchertach mac Ercae each die a threefold death on Samhain, which involves wounding, burning and drowning, and of which they are forewarned. In the tale Togail Bruidne Dá Derga ('The Destruction of Dá Derga's Hostel'), king Conaire Mór also meets his death on Samhain after breaking his geasa (prohibitions or taboos). He is warned of his impending doom by three undead horsemen who are messengers of Donn, god of the dead. The Boyhood Deeds of Fionn tells how each Samhain the men of Ireland went to woo a beautiful maiden who lives in the fairy mound on Brí Eile (Croghan Hill). It says that each year someone would be killed "to mark the occasion", by persons unknown. Some academics suggest that these tales recall human sacrifice, and argue that several ancient Irish bog bodies (such as Old Croghan Man) appear to have been kings who were ritually killed, some of them around the time of Samhain.

In the Echtra Neraí ('The Adventure of Nera'), King Ailill of Connacht sets his retinue a test of bravery on Samhain night. He offers a prize to whoever can make it to a gallows and tie a band around a hanged man's ankle. Each challenger is thwarted by demons and runs back to the king's hall in fear. However, Nera succeeds, and the dead man then asks for a drink. Nera carries him on his back and they stop at three houses. They enter the third, where the dead man drinks and spits it on the householders, killing them. Returning, Nera sees a fairy host burning the king's hall and slaughtering those inside. He follows the host through a portal into the Otherworld. Nera learns that what he saw was only a vision of what will happen the next Samhain unless something is done. He is able to return to the hall and warns the king.

The tale Aided Chrimthainn maic Fidaig ('The Killing of Crimthann mac Fidaig') tells how Mongfind kills her brother, king Crimthann of Munster, so that one of her sons might become king. Mongfind offers Crimthann a poisoned drink at a feast, but he asks her to drink from it first. Having no other choice but to drink the poison, she dies on Samhain eve. The Middle Irish writer notes that Samhain is also called Féile Moingfhinne (the Festival of Mongfind or Mongfhionn), and that "women and the rabble make petitions to her" at Samhain.Byrne, Francis John. Irish King and High Kings. Four Courts Press, 2001. p. 75

Many other events in Irish mythology happen or begin on Samhain. The invasion of Ulster that makes up the main action of the Táin Bó Cúailnge ('Cattle Raid of Cooley') begins on Samhain. As cattle-raiding typically was a summer activity, the invasion during this off-season surprised the Ulstermen. The Second Battle of Magh Tuireadh also begins on Samhain. The Morrígan and The Dagda meet and have sex before the battle against the Fomorians; in this way the Morrígan acts as a sovereignty figure and gives the victory to the Dagda's people, the Tuatha Dé Danann. In Aislinge Óengusa ('The Dream of Óengus') it is when he and his bride-to-be switch from bird to human form, and in Tochmarc Étaíne ('The Wooing of Étaín') it is the day on which Óengus claims the kingship of Brú na Bóinne.

Several sites in Ireland are especially linked to Samhain. Each Samhain a host of otherworldly beings was said to emerge from Oweynagat ("cave of the cats"), at Rathcroghan in County Roscommon. The Hill of Ward (or Tlachtga) in County Meath is thought to have been the site of a great Samhain gathering and bonfire; the Iron Age ringfort is said to have been where the goddess or druid Tlachtga gave birth to triplets and where she later died.

In The Stations of the Sun: A History of the Ritual Year in Britain (1996), Ronald Hutton writes: "No doubt there were [pagan] religious observances as well, but none of the tales ever portrays any". The only historic reference to pagan religious rites is in the work of Geoffrey Keating (died 1644), but his source is unknown. Hutton says it may be that no religious rites are mentioned because, centuries after Christianization, the writers had no record of them. Hutton suggests Samhain may not have been particularly associated with the supernatural. He says that the gatherings of royalty and warriors on Samhain may simply have been an ideal setting for such tales, in the same way that many Arthurian tales are set at courtly gatherings at Christmas or Pentecost.

Historic customs
Samhain was one of the four main festivals of the Gaelic calendar, marking the end of the harvest and beginning of winter. Samhain customs are mentioned in several medieval texts. In Serglige Con Culainn ('Cúchulainn's Sickbed'), it is said that the festival of the Ulaid at Samhain lasted a week: Samhain itself, and the three days before and after. It involved great gatherings at which they held meetings, feasted, drank alcohol, and held contests The Celts also recorded horse racing as part of their Samhain festivities. The Togail Bruidne Dá Derga notes that bonfires were lit at Samhain and stones cast into the fires. It is mentioned in Geoffrey Keating's Foras Feasa ar Éirinn, which was written in the early 1600s but draws on earlier medieval sources, some of which are unknown. He claims that the feis of Tara was held for a week every third Samhain, when the nobles and ollams of Ireland met to lay down and renew the laws, and to feast. He also claims that the druids lit a sacred bonfire at Tlachtga and made sacrifices to the gods, sometimes by burning them in the fire. He adds that all other fires were doused and then re-lit from this bonfire.

Traditionally, Samhain was a time to take stock of the herds and food supplies. Cattle were brought down to the winter pastures after six months in the higher summer pastures. It was also the time to choose which animals would need to be slaughtered for the winter. This custom is still observed by many who farm and raise livestockMcNeill, F. Marian (1961, 1990) The Silver Bough, Vol. 3. William MacLellan, Glasgow  pp. 11–46 because it is when meat will keep since the freeze has come and also since summer grass is gone and free foraging is no longer possible. It is thought that some of the rituals associated with the slaughter have been transferred to other winter holidays. On St. Martin's Day (11 November) in Ireland, an animal—usually a rooster, goose or sheep—would be slaughtered and some of its blood sprinkled on the threshold of the house. It was offered to Saint Martin, who may have taken the place of a god or gods, and it was then eaten as part of a feast. This custom was common in parts of Ireland until the 19th century, and was found in some other parts of Europe. At New Year in the Hebrides, a man dressed in a cowhide would circle the township sunwise. A bit of the hide would be burnt and everyone would breathe in the smoke. These customs were meant to keep away bad luck, and similar customs were found in other Celtic regions.

Ritual bonfires
As at Bealtaine, bonfires were lit on hilltops at Samhain and there were rituals involving them. However, by the modern era, they only seem to have been common in parts of the Scottish Highlands, on the Isle of Man, in north and mid Wales, and in parts of Ulster. F. Marian McNeill says that a force-fire (or need-fire) was the traditional way of lighting them, but notes that this method gradually died out. Likewise, only certain kinds of wood were traditionally used, but later records show that many kinds of flammable material were burnt. It is suggested that the fires were a kind of imitative or sympathetic magic—they mimicked the Sun, helping the "powers of growth" and holding back the decay and darkness of winter. They may also have served to symbolically "burn up and destroy all harmful influences". Accounts from the 18th and 19th centuries suggest that the fires (as well as their smoke and ashes) were deemed to have protective and cleansing powers.

In Moray, boys asked for bonfire fuel from each house in the village. When the fire was lit, "one after another of the youths laid himself down on the ground as near to the fire as possible so as not to be burned, and in such a position as to let the smoke roll over him. The others ran through the smoke and jumped over him". When the bonfire burnt down, they scattered the ashes, vying with each other who should scatter them most. Sometimes, two bonfires would be built side by side, and the people—sometimes with their livestock—would walk between them as a cleansing ritual. The bones of slaughtered cattle were said to have been cast upon bonfires. In the pre-Christian Gaelic world, cattle were the main form of wealth and were the center of agricultural and pastoral life.

People also took flames from the bonfire back to their homes. In parts of Scotland, torches of burning fir or turf were carried sunwise around homes and fields to protect them. In some places, people doused their hearth fires on Samhain night. Each family then solemnly re-lit its hearth from the communal bonfire, thus bonding the community together. The 17th century writer Geoffrey Keating claimed that this was an ancient tradition, instituted by the druids. Dousing the old fire and bringing in the new may have been a way of banishing evil, which was done at New Year festivals in many countries.

Divination rituals
The bonfires were used in divination rituals, although not all divination involved fire. In 18th century Ochtertyre, a ring of stones—one for each person—was laid round the fire, perhaps on a layer of ashes. Everyone then ran round it with a torch, "exulting". In the morning, the stones were examined and if any was mislaid it was said that the person it represented would not live out the year. A similar custom was observed in northern Wales and in Brittany. James Frazer says that this may come from "an older custom of actually burning them" (i.e. human sacrifice) or may have always been symbolic. Divination has likely been a part of the festival since ancient times, and it has survived in some rural areas.

At household festivities throughout the Gaelic regions and Wales, there were many rituals intended to divine the future of those gathered, especially with regard to death and marriage.Hutton, p. 380 Apples and hazelnuts were often used in these divination rituals or games. In Celtic mythology, apples were strongly associated with the Otherworld and immortality, while hazelnuts were associated with divine wisdom. One of the most common games was apple bobbing. Another involved hanging a small wooden rod from the ceiling at head height, with a lit candle on one end and an apple hanging from the other. The rod was spun round and everyone took turns to try to catch the apple with their teeth. Apples were peeled in one long strip, the peel tossed over the shoulder, and its shape was said to form the first letter of the future spouse's name.

Two hazelnuts were roasted near a fire; one named for the person roasting them and the other for the person they desired. If the nuts jumped away from the heat, it was a bad sign, but if the nuts roasted quietly it foretold a good match.Danaher (1972), p. 219  Items were hidden in food—usually a cake, barmbrack, cranachan, champ or sowans—and portions of it served out at random. A person's future was foretold by the item they happened to find; for example a ring meant marriage and a coin meant wealth. A salty oatmeal bannock was baked; the person ate it in three bites and then went to bed in silence without anything to drink. This was said to result in a dream in which their future spouse offers them a drink to quench their thirst. Egg whites were dropped in water, and the shapes foretold the number of future children. Children would also chase crows and divine some of these things from the number of birds or the direction they flew.

Aos sí at Samhain
As noted earlier, Samhain was seen as a liminal time, when the boundary between this world and the Otherworld could more easily be crossed. This meant the aos sí, the 'spirits' or 'fairies', could more easily come into our world. Many scholars see the aos sí as remnants of the pagan gods and nature spirits.Santino, Jack. The Hallowed Eve: Dimensions of Culture in a Calendar Festival of Northern Ireland. University Press of Kentucky, 1998. p. 105 At Samhain, it was believed that the aos sí needed to be propitiated to ensure that the people and their livestock survived the winter. As such, offerings of food and drink would be left outside for the aos sí.McNeill, F. Marian (1961). The Silver Bough, Volume 3. p. 34. Portions of the crops might also be left in the ground for them.

Hebrides offering to Shoney
One custom—described a "blatant example" of a "pagan rite surviving into the Christian epoch"—was observed in the Outer Hebrides until the early 19th century. On 31 October, the locals would go down to the shore. One man would wade into the water up to his waist, where he would pour out a cup of ale and ask 'Seonaidh' ('Shoney'), whom he called "god of the sea", to bestow blessings on them. People also took special care not to offend the aos sí and sought to ward-off any who were out to cause mischief. They stayed near to home or, if forced to walk in the darkness, turned their clothing inside-out or carried iron or salt to keep them at bay. The dead were also honored at Samhain. The beginning of winter may have been seen as the most fitting time to do so, as it was a time of 'dying' in nature. The souls of the dead were thought to revisit their homes seeking hospitality. Places were set at the dinner table and by the fire to welcome them.McNeill, The Silver Bough, Volume 3, pp. 11–46

Connection to the dead
The belief that the souls of the dead return home on one night of the year and must be appeased seems to have ancient origins and is found in many cultures throughout the world. James Frazer suggests "It was perhaps a natural thought that the approach of winter should drive the poor, shivering, hungry ghosts from the bare fields and the leafless woodlands to the shelter of the cottage". However, the souls of thankful kin could return to bestow blessings just as easily as that of a wronged person could return to wreak revenge.

Mumming and guising
Mumming and guising was a part of Samhain from at least the 16th century and was recorded in parts of Ireland, Scotland, Mann and Wales. It involved people going from house to house in costume (or in disguise), usually reciting songs or verses in exchange for food. It is suggested that it evolved from a tradition whereby people impersonated the aos sí, or the souls of the dead, and received offerings on their behalf. Impersonating these spirits or souls was also believed to protect oneself from them. S. V. Peddle suggests the guisers "personify the old spirits of the winter, who demanded reward in exchange for good fortune". McNeill suggests that the ancient festival included people in masks or costumes representing these spirits and that the modern custom came from this. In Ireland, costumes were sometimes worn by those who went about before nightfall collecting for a Samhain feast.

In parts of southern Ireland during the 19th century, the guisers included a hobby horse known as the Láir Bhán (white mare). A man covered in a white sheet and carrying a decorated horse skull (representing the Láir Bhán) would lead a group of youths, blowing on cow horns, from farm to farm. At each they recited verses, some of which "savoured strongly of paganism", and the farmer was expected to donate food. If the farmer donated food he could expect good fortune from the 'Muck Olla'; not doing so would bring misfortune. This is akin to the Mari Lwyd (grey mare) procession in Wales, which takes place at Midwinter. In Wales the white horse is often seen as an omen of death. In some places, young people cross-dressed. In Scotland, young men went house-to-house with masked, veiled, painted or blackened faces, often threatening to do mischief if they were not welcomed. This was common in the 16th century in the Scottish countryside and persisted into the 20th. It is suggested that the blackened faces comes from using the bonfire's ashes for protection. Elsewhere in Europe, costumes, mumming and hobby horses were part of other yearly festivals. However, in the Celtic-speaking regions they were "particularly appropriate to a night upon which supernatural beings were said to be abroad and could be imitated or warded off by human wanderers".

Mischief Night pranks
Hutton writes: "When imitating malignant spirits it was a very short step from guising to playing pranks". Playing pranks at Samhain is recorded in the Scottish Highlands as far back as 1736 and was also common in Ireland, which led to Samhain being nicknamed "Mischief Night" in some parts. Wearing costumes at Halloween spread to England in the 20th century, as did the custom of playing pranks, though there had been mumming at other festivals. At the time of mass transatlantic Irish and Scottish immigration, which popularised Halloween in North America, Halloween in Ireland and Scotland had a strong tradition of guising and pranks. Trick-or-treating may have come from the custom of going door-to-door collecting food for Samhain feasts, fuel for Samhain bonfires and/or offerings for the aos sí. Alternatively, it may have come from the All Saints/All Souls custom of collecting soul cakes.

The "traditional illumination for guisers or pranksters abroad on the night in some places was provided by turnips or mangel wurzels, hollowed out to act as lanterns and often carved with grotesque faces". They were also set on windowsills. By those who made them, the lanterns were variously said to represent the spirits or supernatural beings, or were used to ward off evil spirits.Palmer, Kingsley. Oral folk-tales of Wessex. David & Charles, 1973. pp. 87–88 These were common in parts of Ireland and the Scotland into the 20th century. They were also found in Somerset (see Punkie Night). In the 20th century they spread to other parts of England and became generally known as jack-o'-lanterns.

Celtic Revival
During the late 19th and early 20th century Celtic Revival, there was an upswell of interest in Samhain and the other Celtic festivals. Sir John Rhys put forth that it had been the "Celtic New Year". He inferred it from contemporary folklore in Ireland and Wales, which he felt was "full of Hallowe'en customs associated with new beginnings". He visited Mann and found that the Manx sometimes called 31 October "New Year's Night" or Hog-unnaa. The Tochmarc Emire, written in the Middle Ages, reckoned the year around the four festivals at the beginning of the seasons, and put Samhain at the beginning of those. However, Hutton says that the evidence for it being the Celtic or Gaelic New Year's Day is flimsy. Rhys's theory was popularised by Sir James George Frazer, though at times he did acknowledge that the evidence is inconclusive. Frazer also put forth that Samhain had been the pagan Celtic festival of the dead and that it had been Christianized as All Saints and All Souls. Since then, Samhain has been popularly seen as the Celtic New Year and an ancient festival of the dead. The calendar of the Celtic League, for example, begins and ends at Samhain.

Related festivals

In the Brythonic branch of the Celtic languages, Samhain is known as the 'calends of winter'. The Brythonic lands of Wales, Cornwall and Brittany held festivals on 31 October similar to the Gaelic one. In Wales it is Calan Gaeaf, in Cornwall it is Allantide or Kalan Gwav and in Brittany it is Kalan Goañv.

The Manx celebrate Hop-tu-Naa on 31 October, which is a celebration of the original New Year's Eve. Traditionally, children carve turnips rather than pumpkins and carry them around the neighbourhood singing traditional songs relating to hop-tu-naa.

Allhallowtide
The Roman Catholic holy day of All Saints (or All Hallows) was introduced in the year 609, but was originally celebrated on 13 May. In 835, Louis the Pious switched it to 1 November in the Carolingian Empire, at the behest of Pope Gregory IV. However, from the testimony of Pseudo-Bede, it is known that churches in what are now England and Germany were already celebrating All Saints on 1 November at the beginning of the 8th century.Pseudo-Bede, Homiliae subdititiae; John Hennig, 'The Meaning of All the Saints', Mediaeval Studies 10 (1948), 147–61. Thus, Louis merely made official the custom of celebrating it on 1 November. James Frazer suggests that 1 November was chosen because it was the date of the Celtic festival of the dead (Samhain)—the Celts had influenced their English neighbours, and English missionaries had influenced the Germans. However, Ronald Hutton points out that, according to Óengus of Tallaght (d. ca. 824), the 7th/8th century church in Ireland celebrated All Saints on 20 April. He suggests that the 1 November date was a Germanic rather than a Celtic idea. In the 11th century, 2 November became established as All Souls' Day. This created the three-day observance known as Allhallowtide: All Hallows' Eve (31 October), All Hallows' Day (1 November), and All Souls' Day (2 November).

It is widely believed that many of the modern secular customs of All Hallows' Eve (or Halloween) were influenced by the festival of Samhain.

Neopaganism

Samhain and Samhain-based festivals are held by some Neopagans. As there are many kinds of Neopaganism, their Samhain celebrations can be very different despite the shared name. Some try to emulate the historic festival as much as possible. Other Neopagans base their celebrations on sundry unrelated sources, Gaelic culture being only one of the sources.Adler, Margot (1979, revised edition 2006) Drawing Down the Moon: Witches, Druids, Goddess-Worshippers, and Other Pagans in America Today. Boston: Beacon Press . pp. 3, 243–99 Folklorist Jenny Butler describes how Irish pagans pick some elements of historic Samhain celebrations and meld them with references to the Celtic past, making a new festival of Samhain that is inimitably part of neo-pagan culture.

Neopagans usually celebrate Samhain on 31 October – 1 November in the Northern Hemisphere and 30 April – 1 May in the Southern Hemisphere, beginning and ending at sundown. Some Neopagans celebrate it at the astronomical midpoint between the autumn equinox and winter solstice (or the full moon nearest this point). In the Northern Hemisphere, this midpoint is when the ecliptic longitude of the Sun reaches 225 degrees. In 2015, this is on 7 November, at 17:44 GMT.

Celtic Reconstructionism
Like other Reconstructionist traditions, Celtic Reconstructionist Pagans emphasize historical accuracy. They base their celebrations and rituals on traditional lore as well as research into the beliefs of the polytheistic Celts.Bonewits, Isaac (2006) Bonewits's Essential Guide to Druidism. New York: Kensington Publishing Group . pp. 128–40, 179, 183–84

Celtic Reconstructionist Pagans (or CRs) often celebrate Samhain on the date of first frost, or when the last of the harvest is in and the ground is dry enough to have a bonfire. Some follow the old tradition of building two bonfires, which celebrants and livestock then walk or dance between as a ritual of purification. For CRs, it is a time when the dead are especially honoured. Though CRs make offerings at all times of the year, Samhain is a time when more elaborate offerings are made to specific ancestors. This may involve making a small shrine. Often there will be a meal, where a place for the dead is set at the table and they are invited to join. Traditional tales may be told and traditional songs, poems and dances performed. A western-facing door or window may be opened and a candle left burning on the windowsill to guide the dead home. Divination for the coming year is often done, whether in all solemnity or as games for the children. The more mystically inclined may also see this as a time for deeply communing with their deities, especially those seen as being particularly linked with this festival.

Wicca
Wiccans celebrate a variation of Samhain as one of the yearly Sabbats of the Wheel of the Year. It is deemed by most Wiccans to be the most important of the four "greater Sabbats". Samhain is seen by some Wiccans as a time to celebrate the lives of those who have died, and it often involves paying respect to ancestors, family members, elders of the faith, friends, pets and other loved ones who have died.  In some rituals the spirits of the dead are invited to attend the festivities.  It is seen as a festival of darkness, which is balanced at the opposite point of the wheel by the spring festival of Beltane, which Wiccans celebrate as a festival of light and fertility.

Wiccans believe that at Samhain the veil between this world and the afterlife is at its thinnest point of the whole year, making it easier to communicate with those who have left this world.
