Halloween has a way of arriving faster than anyone plans for. One week it's a date somewhere out on the calendar; the next it's the 29th, the good costumes are gone in your size, and you're standing in a picked-over candy aisle doing mental arithmetic about how many children live on your street.
This guide fixes that with two things: a live countdown, and a plan that works backwards from the 31st. Nothing here needs to be done today — but each item has a point past which it gets harder, more expensive, or impossible, and that's what the weeks below are for.
When is Halloween 2026?
Halloween 2026 falls on Saturday, October 31. Halloween is always October 31, but the day of the week it lands on changes the night more than people expect — and 2026 draws the best one.
A Saturday Halloween means three things worth planning around:
- More trick-or-treaters, out later. No school the next morning, so families start earlier and stay out longer. If you normally run out of candy, this is the year you'll run out sooner.
- Parties on the night itself rather than shifted to the nearest weekend — so invitations and costumes compete for the same date rather than spreading across two.
- A busier final week in stores. Everyone has the weekend before free for shopping and decorating, which clears shelves faster.
Why starting early actually matters
This isn't just enthusiasm. According to the National Retail Federation, Halloween has grown into a genuinely large event — US Halloween spending reached a record $13.1 billion in 2025, with $3.9 billion of that on candy alone. Two in three people hand out candy, and about half dress up or decorate.
The NRF has also found that nearly half of Halloween shoppers start buying before October even begins. That's the part that matters to you: by the time the shelves look properly stocked in mid-October, a large share of the good stock has already gone to people who started in September.
Six weeks out: decide your costume
The single most common Halloween regret is leaving the costume too late — and it's rarely because ideas ran out. It's because the size ran out. Costume stock is deep in style and shallow in size, so common adult and children's sizes disappear first while the rails still look full.
At six weeks, you only need to make the decision, not buy anything:
- Decide whether you're going solo, as a couple, as a family, or in a group. Group costumes need the longest lead time because everyone has to agree.
- Work out roughly what you want to spend. This narrows the options far faster than browsing does.
- Check what you already own. A surprising number of costumes are one purchased item away from finished.
If you're stuck for ideas, the Halloween Costume Generator filters by age, style, budget, group size and effort level, and gives you the accessory list and a DIY version of each idea — which is the fastest way to find out whether an idea is actually within reach.
Four weeks out: buy it, and plan the party
Now buy the costume. Anything being shipped, altered or made needs to be ordered this week — allow extra if it's coming from overseas.
If you're hosting, this is also when the party takes shape. Decide the four things everything else follows from: the date (Saturday the 31st itself, or the Friday before), the guest count, the budget, and the theme. Everything else — food, games, decorations, music — is downstream of those four, which is why deciding them early makes the rest fast.
The Halloween Party Planner takes those inputs and produces the whole plan: theme, decorations, food, drinks, games, music, an hour-by-hour timeline, a shopping list and a cleanup plan. Print it and work through it rather than rebuilding it in your head every few days.
Three weeks out: invitations and colors
Send invitations now. Two to three weeks is the sweet spot — early enough that guests can sort a costume, late enough that they won't forget. Always include an RSVP deadline; without one, half your guests will decide on the day and you'll shop blind.
The Halloween Invitation Generator writes the wording for you in seven tones, from spooky to kid-friendly, and you can copy it into a message or print it as a card.
This is also the right week to sort your costume's finer details — the colors, accessories and makeup that separate a costume that photographs well from one that looks assembled. The Costume Color Matcher gives you a three-color palette with hex codes so you can match fabric or face paint properly, plus a styling note for the look you've chosen.
Two weeks out: candy and decorations
Buy candy now — not earlier. Two weeks is late enough that it survives until the 31st and early enough that you get a choice. Buy earlier and you will eat it; that isn't a joke, it's the most reliable pattern in Halloween planning.
How much? Multiply the trick-or-treaters you expect by two or three pieces, add a buffer, then round up to whole bags. On a quiet street that might be 20–50 children; on a busy, well-decorated one it can be 200 or more. Local knowledge beats any average — ask a neighbor who's been there longer, and remember to nudge the number up for a Saturday.
Decorations can go up any time from mid-October. Test string lights and any inflatables before the day — a dead set of lights discovered on the 31st is a small tragedy with no fix.
One week out: pumpkins
Here's the mistake almost everyone makes once: carving too early. A carved pumpkin only lasts about five to ten days, and considerably less in warm or humid weather. Carve on the 20th and you'll have a collapsed, moldy face on your porch by Halloween night.
Buy the pumpkin whenever you see a good one — uncarved, it keeps for weeks. Carve it in the last few days. Two things extend its life: scrape the inside walls down to about an inch thick so there's less flesh to rot, and use a battery tealight rather than a candle, which avoids cooking the pumpkin from the inside.
If you want a design that matches your skill level rather than one you'll abandon halfway, the Pumpkin Carving Idea Generator gives you designs with the tools needed, a realiztic time estimate and step-by-step instructions — including no-carve painted and drilled options for younger children.
The final days
By now the big decisions are made. What's left is the small stuff that ruins an evening if it's forgotten:
- Print your games. If you're running Halloween Bingo or a Scavenger Hunt, print one card or clue sheet per player the day before — every card generates differently, so print, generate, print again.
- Try the costume on. Fully. Including shoes, mask and anything that has to be worn for four hours. Problems found now are fixable.
- Charge or buy batteries for lights, tealights and flashlights.
- Check the weather. A costume that needs a coat over it isn't a costume any more — plan a layer that works with it.
- Set out the candy bowl and a spare bag hidden behind the door, so an early handful doesn't empty you at 6:30.

Frequently asked questions
Halloween 2026 falls on Saturday, October 31. It lands on a weekend, which historically means bigger parties, more trick-or-treaters out later, and busier stores in the final week.
The countdown at the top of this page updates every second and shows the exact days, hours and minutes remaining. It rolls over to the following year automatically once the night has passed.
About three to four weeks ahead. Costumes sell out by size long before they sell out by style, so the common adult and children's sizes go first. If you're ordering online or having something made, give yourself four to six weeks.
No more than about a week. A carved pumpkin usually lasts five to ten days, and less in warm or humid weather. Buy the pumpkin whenever you like, but carve it in the last few days before Halloween.
Multiply the number of trick-or-treaters you expect by two or three pieces each, then add roughly 15% spare. For 60 children at three pieces that's about 210 pieces — two large bags. Because Halloween 2026 is on a Saturday, budget on the higher side.
Two weeks before the party. That gives guests time to sort a costume and gives you time to count heads before you shop for food.
