When is Halloween 2026?
Halloween is always on 31 October, year in and year out, just as Bonfire Night is always on 5 November. It sits on the eve of All Saints' Day, which is where it gets its name, and that fixed spot on the calendar means you can start planning the moment the nights begin drawing in.

What day of the week is Halloween this year?
In 2026 the 31st falls on the weekday shown in Saturday, 31 October 2026 above. If it lands midweek, lots of people shift the parties to the nearest Friday or Saturday so there's time to enjoy it properly, while the trick-or-treating itself usually stays on the 31st, since that's when the neighbours are expecting little visitors at the door.
The origins of Halloween
Halloween has roots stretching all the way back to the ancient Celtic festival of Samhain, which marked the end of the harvest and the start of the dark half of the year. The Celts believed that on this night the boundary between the living and the dead grew thin, so it was a time of bonfires, storytelling and a healthy respect for whatever might be wandering about.
Later this became woven into the Christian calendar. The evening before All Saints' Day was known as "All Hallows' Eve", and over time that name was worn down to the Halloween we use today. So beneath all the sweets and silly masks there's a genuinely old tradition, and that's part of what makes the night feel a little bit magical.
How Halloween is celebrated in the UK
Halloween has grown enormously in Britain over the last few decades. What was once a fairly quiet evening has become one of autumn's biggest nights, with whole streets decorated in pumpkins and front gardens turned into mini graveyards. The American influence, by way of films and television, certainly gave it a push, but the British version has very much taken on a life of its own.
Trick-or-treating is the heart of it for the children. The usual rule is simple: a porch light on and a bit of decoration outside means a household is happy to welcome visitors, while a dark, undecorated house is best left in peace. The rounds tend to run between around 5pm and 9pm, so everyone's home at a sensible hour.
For the grown-ups, it's often pumpkin carving at the kitchen table, a horror film with the lights down, or a proper fancy-dress party. One small kindness worth remembering: go gently with the youngest ones. A truly terrifying mask and a loud roar can tip a three-year-old from delighted to in tears, so it's lovely to dial it down when the tiny ones turn up.
Getting costume-ready for Halloween
It's the costume that really makes Halloween. Some go for the classic spooky route with ghosts, witches and vampires, while others prefer something funny and unexpected that gets a laugh rather than a scream. Both work a treat, whether you want the whole family to match or one person to stand out. Have a browse through our Halloween collection if you need a nudge of inspiration for this year's outfit.
If you'd rather be cosy than creepy, a snug night in is a fine way to mark the occasion too. A HappyHoodie, our giant super-soft oversized hoodie that's basically a blanket you can wear, is just the thing for curling up with a scary film while the wind rattles the windows outside. Wizard fans might also enjoy our Harry Potter range for a bit of magical dressing-up.
Whatever you settle on, a few carved pumpkins in the window, a string of lights and a bowl of sweets by the door will set the mood nicely. Now you know exactly when Halloween falls and how many days you've got left, so all that's left is to sort the costume and get the cauldron bubbling.
