When is Halloween?
In 2026, Halloween falls on Saturday, October 31, 2026. It is an observance rather than a federal holiday, so federal offices and most businesses follow their normal schedules.
History of Halloween
Halloween has especially deep Irish roots in Samhain, the Gaelic seasonal festival marking the end of harvest and the beginning of winter. Folklore associated the night with thresholds, ancestors and the otherworld; many customs later mixed with Christian All Hallows traditions.
It is not itself a public holiday in Ireland, but its cultural reach is unmistakable. Costumes, food, bonfires and community festivals make it one of the country’s most visible autumn observances, while the following Monday public holiday provides a practical long-weekend setting in many years.
Irish and Scottish migration helped carry Halloween customs to North America, where they changed and later circulated internationally. In Ireland, carved turnips preceded pumpkins, while barmbrack divination and games such as snap-apple retained local forms. Samhain was a seasonal complex rather than simply an ancient version of modern trick-or-treating, so claims of direct unchanged survival should be avoided.
How Halloween is observed
Halloween is a cultural observance, not a statutory public holiday. School and work schedules normally continue unless the date coincides with another closure.
Traditions of Halloween

Barmbrack traditionally concealed small tokens interpreted playfully as signs of marriage, travel or future fortune, though safety now limits objects. Its expression varies across Ireland’s counties, communities and households.
Living tradition
Turnip lanterns belong to older Irish practice, while pumpkins are easier to carve and dominate many contemporary household displays. Its expression varies across Ireland’s counties, communities and households.
Planning and participation
Samhain-themed storytelling, fire spectacles and folklore programmes draw on Irish heritage while modern children follow local trick-or-treating customs. Its expression varies across Ireland’s counties, communities and households.
