How Many Days Until Halloween?

The Celtic Samhain: Where Halloween Began

Halloween has roots stretching back more than 2,000 years to the Celtic peoples of Ireland, Scotland, and northern France. Their calendar marked the year in two halves: the light half (summer) and the dark half (winter). The boundary fell on October 31, which the Celts called Samhain (pronounced “SOW-in,” rhyming with “cow-in”).

Samhain was the most significant of the four seasonal festivals in the Celtic year. It marked the end of the harvest, the gathering of livestock for the winter, and the transition into the cold dark months. The Celts believed that on this night, the barrier between the world of the living and the realm of the dead became thin enough for spirits to pass through.

Spirits of ancestors were welcomed at Samhain, with offerings of food and drink left outside homes. But not all spirits crossing over were friendly. People lit bonfires on hilltops to ward off malevolent entities, and some wore costumes made from animal hides to disguise themselves from wandering spirits. These early disguises are the distant origin of modern Halloween costumes.

The bonfires served a double purpose: they lit the way for friendly souls and sent the unfriendly ones back. Embers from the communal fire were carried home to relight household hearths, symbolizing community and protection through the dark months.

Roman Influence: Two Festivals Merged With Samhain

When Rome conquered Celtic territories in Britain and Gaul during the first and second centuries AD, Roman festivals blended with local Celtic practices. Two Roman observances shaped what Samhain would eventually become.

Feralia was a late October Roman festival honoring the dead. Romans believed the spirits of the departed needed food and offerings to rest peacefully. Feralia involved visiting graves, leaving food, and performing rites to keep the dead satisfied so they would not trouble the living.

Pomona was the festival of the Roman goddess of fruit trees and harvests, observed around this same period. Pomona’s symbol was an apple, which may explain how apple-bobbing entered Halloween traditions. The practice of dunking for apples in a barrel of water may be a survival of divination games originally associated with Pomona worship.

The merger of Samhain, Feralia, and Pomona created a cultural blend: harvest celebration, honoring the dead, and protective rituals against wandering spirits. This fusion happened over several generations as Roman officials allowed local religious practices to continue alongside Roman ones.

The Christian Church and All Hallows Eve

As Christianity spread through Europe, the Church often adopted existing festivals and gave them new Christian meaning rather than eliminating them entirely. Pope Boniface IV dedicated the Pantheon in Rome to Christian martyrs in 609 AD, establishing All Martyrs Day. Pope Gregory III later expanded this to include all saints and moved the observance to November 1, calling it All Saints Day (also called All Hallows Day, with “hallows” meaning holy persons).

November 2 became All Souls Day, when the Church prayed for souls in purgatory. The evening before All Hallows Day became All Hallows Eve, contracted over time to Halloween.

The Church’s establishment of All Hallows Day on November 1 may have been deliberate timing to provide a Christian observance that overlapped with the existing Celtic and pagan end-of-year festivals. By giving communities an approved Christian holiday at the same time as Samhain, Church authorities hoped to replace the older practices with sanctioned observances.

The result was a layered holiday: Christian in its official name and calendar placement, but carrying older beliefs about spirits, the dead, and the boundary between worlds.

Halloween Comes to North America

Halloween’s arrival in North America came primarily through Irish and Scottish immigration in the 19th century, particularly after the Great Famine (1845-1852) drove millions of Irish to the United States and Canada.

Irish immigrants brought their Halloween traditions: wearing costumes to confuse spirits, carving lanterns (originally from turnips), and telling ghost stories. These practices mixed with American folk customs and the traditions of other immigrant communities.

Through the late 1800s, Halloween gradually shifted from a community superstition-heavy observance to a neighborhood holiday centered on community gatherings. Women’s magazines and community organizations began publishing suggestions for Halloween parties, treating it as an occasion for games and decorations rather than for spiritual practices.

By the early 20th century, Halloween had largely shed its overtly supernatural associations for most Americans. What remained was the symbolic vocabulary: ghosts, witches, skeletons, and jack-o-lanterns — now decorative rather than protective.

Trick-or-Treating: How It Developed

Trick-or-treating as Americans know it today developed gradually from several distinct older practices.

Souling was a medieval European practice observed on All Souls Day (November 2). The poor would travel from house to house offering prayers for the household’s deceased relatives in exchange for soul cakes — small baked goods made with spices and currants. The practice provided food for the poor while giving households a way to fund prayers for their dead.

Guising was a Scottish and Irish tradition in which young people went door to door in costume performing songs, poems, or jokes in exchange for food or coins. The performance was the key element — you earned your treat by providing something. Modern trick-or-treating dropped the performance requirement, though the costumed visit from house to house remained.

In North America, organized trick-or-treating began taking shape in the 1920s and spread through the 1930s, partly as a structured alternative to Halloween mischief. Communities found that giving children a structured activity (going door to door for candy) reduced vandalism and pranks that had plagued Halloween nights. The phrase “trick or treat” began appearing in print in the 1930s.

Postwar suburban expansion in the 1950s created the ideal environment for trick-or-treating: safe neighborhoods with single-family homes in close proximity. Candy manufacturers actively marketed to this new suburban demographic, and Halloween candy became an industry. By 1960, trick-or-treating was standard practice across the United States.

Jack-O-Lanterns: From Turnips to Pumpkins

The carved pumpkin is one of Halloween’s most recognizable symbols, but the original jack-o-lantern was not a pumpkin at all.

The tradition traces to an Irish folk tale about a character variously called Stingy Jack or Jack of the Lantern. In the story, Jack was a trickster who outwitted the devil on multiple occasions, at one point trapping the devil in a tree and refusing to let him down until the devil promised never to take Jack’s soul to hell. When Jack died, God rejected him from heaven for his sins, and the devil (bound by his promise) could not take him to hell either. Jack was condemned to wander the earth between worlds, carrying only a burning coal placed inside a carved turnip to light his way.

Irish and Scottish people began carving turnips, beets, and potatoes into lantern shapes to represent Jack, placing them outside homes on Halloween to ward off his wandering spirit and others like it.

When Irish immigrants arrived in North America, they discovered that pumpkins — native to the Americas — were far larger and easier to carve than turnips. Pumpkins became the material of choice. By the mid-1800s, pumpkin carving on Halloween was established in American print media, and illustrated guides to carving jack-o-lanterns appeared in popular magazines.

Today, Americans purchase hundreds of millions of pumpkins for Halloween decoration, and the United States produces over 1 billion pounds of pumpkins per year, with most consumed as Halloween decorations rather than food.

Halloween Costumes: From Disguise to Celebration

The original purpose of Halloween disguises was protection: by wearing animal skins or later masks, Celtic peoples hoped to blend in with wandering spirits or fool them into thinking the wearer was one of them. Irish guisers wore costumes to go door to door; being unrecognized was part of the practice.

In North America, costumes became recreational. Through the early 20th century, homemade costumes dominated — sheets for ghosts, old clothes for scarecrows, makeup for monsters. Commercial costume production began in earnest in the 1930s and 1940s, with companies producing cloth and later plastic costumes tied to popular culture figures.

Television accelerated the trend toward pop culture costumes. Children dressed as television characters, then movie characters, then video game characters. The costume industry now generates over $3 billion annually in the United States alone, with adults spending as much as children.

Pet costumes represent a newer segment: Americans spend hundreds of millions of dollars each year on Halloween costumes for pets, a category that barely existed before the 2000s.

Halloween Around the World

Halloween in its modern form is primarily a North American and Irish phenomenon, but it has spread internationally through cultural exports.

Mexico and Latin America: Dia de los Muertos (Day of the Dead) is observed November 1-2 across Mexico and parts of Central America. While visually overlapping with Halloween in some ways — skulls, skeletons, altars — it is a distinct tradition rooted in indigenous Aztec practices merged with Catholic All Saints Day observances. Families build ofrendas (altars) with photographs, food, and marigolds (believed to guide the dead home by scent). The tone is celebratory rather than frightening. The rise of Halloween imagery in Mexico has generated cultural debate about the displacement of Dia de los Muertos traditions.

United Kingdom and Ireland: Halloween has deep roots in Ireland and Scotland where Samhain originated. Modern Irish Halloween celebrations include bonfires, fireworks, and trick-or-treating. Barmbrack, a fruit bread containing hidden charms, is a traditional Halloween food in Ireland: finding a ring meant marriage; a coin meant wealth; a rag meant poverty. In Wales, Nos Galan Gaeaf (Winter’s Eve) had its own traditions distinct from Irish Samhain.

Japan and South Korea: Urban Halloween celebrations have grown significantly in both countries since the 1990s, concentrated in entertainment districts. Tokyo’s Shibuya district hosts large street Halloween gatherings. These celebrations are largely social and costumed rather than rooted in local tradition, representing an adoption of the American commercial holiday.

Germany and Austria: Halloween arrived in German-speaking countries primarily in the 1990s. It has been embraced commercially and among younger generations, though it sometimes faces cultural resistance from those who see it as an American imposition replacing established European autumn traditions.

The Economics of Halloween

Halloween is the second-largest commercial holiday in the United States by retail spending, trailing only Christmas. The National Retail Federation tracks annual Halloween spending and has consistently recorded totals above $10 billion in recent years.

Spending breaks down across several categories:

Costumes: Adults, children, and pets all drive costume spending. Adult costume spending exceeds children’s in total dollar terms. Couples and group costumes have grown as a share of the market.

Candy: Candy spending for Halloween regularly exceeds $3 billion. Chocolate candies are the most purchased category, with peanut butter cups, candy bars, and chocolate kisses among top sellers. Hard candies and gummy candies follow.

Decorations: Yard decorations, window decals, string lights, and animatronic displays have grown into a major category. Elaborate yard haunts — homeowner-built Halloween displays meant to be experienced rather than simply viewed — represent a dedicated enthusiast subculture.

Greeting cards: Halloween is the fourth-largest greeting card holiday in the US, behind Christmas, Valentine’s Day, and Mother’s Day.

The candy industry’s association with Halloween is largely a 20th century construction. Before World War II, children collecting treats on Halloween received fruits, nuts, coins, and homemade items as often as candy. The standardization around commercially wrapped candy accelerated in the 1950s partly for food safety reasons (wrapped candy was easier to inspect for tampering) and partly due to candy industry marketing campaigns.
