Countdown to Halloween
Halloween falls on October 31 every year.
Halloween on October 31 brings costumes, trick-or-treating, and pumpkin carving. Kids (and adults) love watching the days-until number shrink through October.
About Halloween
Halloween descends from Samhain, the Gaelic festival marking the end of harvest and the onset of winter, when the boundary between the living and the dead was held to thin. The Christian calendar later placed All Saints' Day on November 1, making October 31 All Hallows' Eve — the source of the modern name. Costumes and door-to-door collecting arrived in North America with Irish and Scottish emigrants in the 19th century and were thoroughly commercialised by the 1950s.
Trick-or-treating, costumes, carved pumpkins, and an escalating domestic arms race in front-yard decoration. The pumpkin is a New World substitution: the original carved lanterns were turnips, which are markedly less cooperative. For households with children, the operative detail is that the entire event happens in a roughly two-hour window after dusk.
Why Halloween falls when it does
October 31 is fixed and never moves, so a Halloween countdown always targets the same date. The weekday does move, and it matters more here than for most holidays: a Friday or Saturday Halloween reliably produces larger parties and earlier trick-or-treating, while a midweek Halloween compresses everything into a short evening. Some communities shift organised events to the nearest weekend, so the local schedule can differ from the calendar date.
Is Halloween a public holiday?
Halloween is not a public holiday anywhere in the United States, and this is the most common misconception about it. Schools, offices, banks, and government services all operate normally on October 31 — which is precisely why a midweek Halloween compresses the whole event into the couple of hours after work and school. The following day, All Saints' Day, is a public holiday in a number of European and Latin American countries, but not in the US.
What to actually count down to
Costumes are the classic failure mode — the good ones sell out, and anything home-made needs a real lead time. A countdown with alerts at three weeks (order or start building), one week (test it on the child, discover it is unwearable), and one day (batteries, face paint, confirm the route) covers most of what actually goes wrong.

How do I put a Halloween countdown on my iPhone?

How many days until Halloween?
The counter above is live to the second and always targets the next October 31. After Halloween passes it rolls forward to the following year on its own.
Is Halloween always on a Friday?
No — October 31 is a fixed date, so the weekday changes each year. Halloween lands on a weekend roughly two years in seven, which is usually when the largest parties and the earliest trick-or-treating happen.
When do trick-or-treating hours usually start?
Most neighbourhoods run from around dusk to roughly two hours after, though this is set locally rather than nationally and some towns publish official hours or move events to the nearest weekend. Worth checking your own municipality rather than assuming.
Where does trick-or-treating come from?
Its clearest ancestors are the medieval British practice of souling — going door to door on All Hallows' Eve offering prayers for the dead in exchange for soul cakes — and Scottish guising, where costumed children performed for food or coin. Irish and Scottish emigration carried both to North America in the 19th century, where they merged into the modern form. The phrase 'trick or treat' itself is surprisingly recent, appearing in North American print only in the 1920s and 30s.
