Samhain, Halloween and the Day of the Dead are three different festivals that happen to share the same few days at the turn of October and November. Samhain is the old Gaelic festival that marks the end of the harvest and the start of the dark half of the year. Halloween is the eve of the Christian feast of All Saints, shaped into its modern form in Ireland, Scotland and North America. The Day of the Dead (Día de los Muertos) is a Mexican celebration on 1 and 2 November in which families welcome their dead home.
They get mixed up constantly, in shops, on social media and sometimes in spiritual circles too. In this article you will find where each one comes from, what people actually do, and how to work with this time of year without borrowing a tradition that is not yours.
What is the main difference between Samhain, Halloween and the Day of the Dead?
The main difference is their root. Samhain grew out of the Gaelic farming year, Halloween out of the Christian calendar of saints, and the Day of the Dead out of Mexican Indigenous ways of honouring the dead that later merged with Catholic All Souls’ Day.
All three deal with death, the dead and the turning of the year. But they ask different things of you. Samhain asks you to face the dark season. Halloween, in its modern form, mostly plays with fear. The Day of the Dead invites specific people back, by name, with their favourite food on the table.

What is Samhain?
Samhain (pronounced roughly SOW-in) is the Gaelic festival that ends the light half of the year and opens the dark half. It begins at sunset on 31 October, because in the old Celtic way of counting, a day started at nightfall.
Early Irish texts describe Samhain as a gathering time when herds came down from summer pastures, debts were settled and kings held assemblies. It was also seen as a night when the boundary to the Otherworld stood open, so the aos sí (the spirit folk) and the dead could move more freely. Fires were lit, people read omens for the coming year, and food was left out. You can read more about the festival itself in my article What Is Samhain? The Old New Year Explained.
The historian Ronald Hutton, who has written the standard study of the British and Irish ritual year (The Stations of the Sun, 1996), points out that we know less about pre-Christian Samhain than many modern books suggest. Much of what we have comes from medieval monks and from later folk custom. That is worth keeping in mind. Samhain today is partly a reconstruction, and that is fine as long as we are honest about it.
What is Halloween?
Halloween is short for All Hallows’ Eve, the evening before All Saints’ Day on 1 November. In the 8th century the Church in Rome began honouring all saints on 1 November, and All Souls’ Day on 2 November followed later for all the faithful dead.
In Ireland and Scotland, the Christian feast and the older Samhain customs ran side by side for centuries. Guising (going door to door in disguise), turnip lanterns and fortune games carried on. When Irish and Scottish families emigrated to North America in the 19th century, they took these customs with them. Turnips became pumpkins, guising became trick or treating, and over the 20th century Halloween turned into the large commercial holiday most of us know today.
So Halloween is not simply Samhain with a new name. It is a Christian date that absorbed Gaelic folk customs and was then reshaped by American popular culture.
What is the Day of the Dead?
The Day of the Dead, Día de los Muertos, is a Mexican festival on 1 and 2 November when the souls of the dead are believed to return to visit their families. 1 November is often for children who have died, 2 November for adults.
Its roots go back to Indigenous Mesoamerican ways of honouring the dead, including Mexica (Aztec) rites. After the Spanish conquest these practices met the Catholic feasts of All Saints and All Souls, and the festival grew from both. In 2008 UNESCO inscribed the Indigenous festivity dedicated to the dead on its list of the Intangible Cultural Heritage of Humanity.
Families build an ofrenda, a home altar with photos of the dead, candles, water, salt, bright orange cempasúchil (marigold) flowers, pan de muerto and the food and drink the person loved. Graves are cleaned and decorated, and people often spend the night in the cemetery, eating, talking and sometimes singing. It is not a Mexican version of Halloween. The point is not fear, but reunion.
Is Halloween the same as Samhain?
No. Halloween took over some of Samhain’s folk customs, but it comes from the Christian eve of All Saints. Samhain is a seasonal festival about the end of the harvest and the dark half of the year. Halloween today is mostly about costumes, sweets and playing with fear.
Why do all three fall at the same time of year?
They overlap because the Church placed All Saints and All Souls on 1 and 2 November, and both Gaelic and Mexican traditions were drawn towards those dates. In the northern hemisphere this is also the time when the light drops away quickly, the fields are empty and the year visibly dies back. Many cultures have looked at that and thought of their dead.
From a shamanic point of view the timing makes sense. When nature pulls inward, it gets easier to turn inward too. People often say the veil is thin at this time. What they usually mean is that the dead feel closer and dreams get louder.
How to work with this season respectfully
You do not have to choose one festival. But it helps to know which one you are actually drawing on. A few simple guidelines:
- Start with your own line. Your grandparents and great-grandparents had their own ways of remembering the dead. Ask your family what they did. It may be closer to your heart than any imported ritual.
- Honour the Day of the Dead without copying it. Sugar skull face paint and ofrendas are part of a living Mexican tradition. If you are not part of that culture, learn about it, support it, and if you are invited, take part. Building one for social media is something else.
- Keep Samhain seasonal. Light a candle or a fire, look back on the year, and name what you are letting go of before winter.
- Let Halloween be fun. There is nothing wrong with a pumpkin and a costume. Just do not mistake it for ceremony.
If you want to understand the question of borrowing better, I have written about it in Shamanism and Cultural Appropriation: Practicing Respectfully. And if remembering your ancestors stirs up more than you expected, Ancestral Healing in Shamanism may help.
From my practice: which festival is actually yours?
Every October someone in my circles asks me whether they are allowed to build an ofrenda, or whether Samhain is the real Halloween. My answer is usually a question back: who do you actually want to remember? Once people name a person, the question of which festival matters much less. Often the ritual becomes very small. Cooking a dish that person used to make, playing their music, saying their name out loud at the table.
For myself I keep the dates apart. On the evening of 31 October I sit with the drum and look at what is ending in my own year. On 1 November, like most families here in Portugal, I think of my own dead. I do not build a Mexican altar for that, because it is not my line, and I would rather honour that tradition by learning about it than by copying it.
If you would like to do this kind of work with others, the Lightkeepers’ Hearth journey circle is where we journey together. Sitting with the ancestors in a group feels very different from sitting alone with them.
Frequently asked questions
No. The Day of the Dead has its own Indigenous and Catholic roots and is about welcoming loved ones who have died. It is not about fear or costumes, even though both fall at the end of October and the start of November.
Partly. Halloween is the Christian eve of All Saints’ Day, but in Ireland and Scotland it absorbed older Samhain folk customs like guising and lanterns. Irish and Scottish emigrants then carried those customs to North America.
Traditionally Samhain begins at sunset on 31 October and runs into 1 November. Some modern practitioners celebrate it at the astronomical midpoint between the autumn equinox and the winter solstice, around 7 November.
You can learn about it, visit public celebrations and take part when you are invited. What many Mexicans find hurtful is when the imagery is used as a costume or a trend without any connection to the people and the meaning behind it.
All three fall where autumn turns towards winter and all three turn attention to death and the dead. Each tradition does that in its own way: Samhain through the seasonal turn, Halloween through play, the Day of the Dead through family reunion.
Whichever of the three is closest to you, this time of year is an invitation to remember. Tell me in the comments: how did your family honour the dead when you were a child?
