TL;DR
Samhain was a Gaelic seasonal festival around 31 October and 1 November, attested in early Irish literature as a time of assemblies, hospitality, and stories of the Otherworld. Halloween grew from All Hallows’ Eve, the night before All Saints’ Day, mixed with later folk customs and Irish-American practice. Much of what you hear about a “Celtic new year” or a single ancient ritual is reconstruction, not a line you can draw straight from the medieval texts.
Samhain is a Gaelic festival at the turn from harvest into winter, around October 31 and November 1. Early Irish sources name it as a point in the year when people gathered, feasted, and told stories in which the boundary with the Otherworld felt thin. Halloween is All Hallows’ Eve, the vigil of All Saints on November 1, later joined by All Souls on November 2. The two calendars sit on the same nights. That overlap, plus later folk custom and Irish migration to North America, is how Samhain’s season became the Halloween most people know. Popular history often fills the gaps with a single “Celtic new year” or a reconstructed priesthood. Those are later readings. Stay with the sources.
In the Western church, All Saints' Day is kept on November 1.
What do early Irish sources actually say about Samhain?
They name it. They do not give you a liturgy.

In medieval Irish literature, Samain or Samhain is a fixed season. Tales set assemblies, raids, and meetings with otherworldly figures then. The Tochmarc Emire (The Wooing of Emer) lists Samhain among the quarter days. Other sagas use it as a dramatic date when kings host, warriors travel, and the sidhe (the mounds and their people) feel close. That is the documented core: a named festival season, public gathering, hospitality, and story.
You do not get a surviving pagan order of service. No early text walks you through a nationwide rite with a high priest, a harvest god, and a script. When modern books supply that picture, they are drawing on later folklore, comparative religion, and nineteenth-century Celtic revival, not quoting a handbook from early Ireland.
If you care about the real festival, read one early tale set at Samhain and notice what the characters do: they feast, they wait, they meet guests from elsewhere. That is the texture the manuscripts give you.
Was Samhain the “Celtic new year”?
The medieval Irish year is not presented that way in the sources we have.
The idea that Samhain was the Celtic new year became popular in modern writing, especially from the nineteenth century onward and in some twentieth-century pagan reconstruction. Historian Ronald Hutton, in The Stations of the Sun (Oxford University Press, 1996), reviews the calendar evidence and treats the “new year” claim as unproven for the early Gaelic record. Early Irish timekeeping names quarter days. It does not clearly mark November 1 as the start of a civil year the way January 1 is for us.
You can still feel Samhain as a threshold. Harvest is in. Dark months are coming. Livestock and people change rhythm. That seasonal turn is real. Calling it “the new year” as if it were a documented civic fact is reconstruction. Keep the threshold. If you want to stay close to the texts, skip the slogan.
How did the Church calendar land on the same nights?
All Saints’ Day (All Hallows) is November 1 in the Western church. The evening before is All Hallows’ Eve, which English shortened to Halloween.

All Souls’ Day, a commemoration of the dead, was widely observed on November 2 from the later Middle Ages.
Pope Gregory III is often associated with a November date for a Roman feast of All Saints in the eighth century. The wider Western adoption of November 1 is a later medieval fact of the calendar, not a secret memo about suppressing Samhain. Christian feasts of the holy dead and Gaelic Samhain occupied overlapping nights in Ireland, Scotland, and other Gaelic regions. People lived both calendars. Folk practice mixed vigil, prayer for the dead, hospitality, and seasonal play.
You do not need a conspiracy to explain the blend. Shared nights plus local custom is enough. When you honor the dead at this season, you stand in a long Christian practice as much as in a Gaelic one. Name both if you want to be honest.
Which Halloween customs are documented folk practice, and which are later American?
Guising, soul cakes, and fires have deep roots in the British Isles as seasonal folk custom. Children and the poor going house to house, sometimes in disguise, asking for food in exchange for songs or prayers for the dead, shows up in later folklore collections. Turnip lanterns appear in Irish and Scottish custom. The carved pumpkin is an American substitution, using a New World squash that was easier to hollow.
If you are Christian, All Hallows and All Souls already give you a frame. If you walk an earth-based path, you can keep Samhain as a Gaelic seasonal feast without claiming a single ancient script. If you are simply curious, learn the Irish word, the quarter-day map, and the difference between a saga date and a modern ritual manual.
Respect means not flattening every culture’s autumn into one costume night, and not pretending every pumpkin on a porch is a surviving Druid rite. It also means not sneering at people who love Halloween as play. Play is part of how the season survived.
If you want company for that kind of careful work, The community is there. Read one primary story. Light one light. Leave invented statistics and guaranteed Otherworld tours out of it.
