Most people think advent calendars end on Christmas Eve. It's a common mistake. You spend twenty-four days peeling back cardboard flaps to find tiny, slightly-waxy chocolates, and then—boom—it's over right when the actual holiday starts. But if you’ve ever felt that weird "post-calendar void" on Christmas morning, you're exactly why the 25 day advent calendar has become such a massive trend.
Honestly, the math just makes more sense.
The tradition of Advent technically starts on the fourth Sunday before Christmas, which means the date shifts every year. It’s messy. To keep things simple, commercial brands standardized the "December 1st to 24th" format decades ago. However, the modern shift toward a full 25-day countdown reflects a change in how we celebrate. We want that final, "big" gift to open alongside the presents under the tree. It feels more complete.
The big shift in how we count down to Christmas
The standard 24-day format is rooted in German Lutheran traditions from the 19th century. Back then, families would just mark chalk lines on a door or light a candle. When Gerhard Lang produced the first printed calendar in the early 1900s, it stopped at the 24th because, in many European cultures, Christmas Eve is the main event. That’s when the feast happens. That’s when the gifts are exchanged.
But in the US, UK, and much of the English-speaking world, December 25th is the peak.

Brands like Liberty London, Fortnum & Mason, and even LEGO eventually realized that ending on the 24th felt like a missed opportunity. If you’re selling a luxury skincare set for $400, why wouldn't you include a full-sized product for the actual day of Christmas? It’s a psychological win for the consumer. You feel like you got a "bonus" day.
Why the extra day matters for your brain
There’s a bit of dopamine science at play here. Anticipation is often more pleasurable than the reward itself. When you use a 25 day advent calendar, you’re extending that "anticipatory high" all the way to the finish line.
I’ve noticed that when a calendar ends on the 24th, the momentum dies just as the house gets the most chaotic. You’re busy prepping turkeys or traveling. Having that one final door to open on the 25th provides a small moment of calm and routine amidst the madness of Christmas morning. It’s a tiny ritual that anchors the day.
Beauty and luxury: The 25-day heavy hitters
The beauty industry basically saved the advent calendar from becoming a dusty relic of grocery store chocolate. If you look at the most sought-after releases from Cult Beauty or Charlotte Tilbury, they almost always lean into the 25-day format.

- The "Full Size" Reveal: Most 25-day sets reserve the twenty-fifth slot for a hero product. It’s usually the item that justifies the entire price of the box.
- The Experience Factor: Brands like Jo Malone use the 25th to include a travel-sized cologne or a signature candle.
Think about it. If you’re paying several hundred dollars, you don't want the experience to end while you're still in your pajamas waiting for the coffee to brew. You want that last heavy drawer to pull open.
What most people get wrong about the cost
People assume a 25 day advent calendar is just "one day more expensive" than a 24-day one. That’s rarely true. In the manufacturing world, adding a 25th compartment often changes the entire structural integrity of the box.
It requires a different die-cut. It changes the shipping weight. Usually, when a company moves from 24 to 25 days, they are signaling that they are a premium brand. It’s a status symbol in the world of holiday retail. You’ll see this with the Swarovski or Tiffany & Co. versions—they aren't just selling you stuff; they’re selling you a curated December experience that culminates in a "Grand Finale."
The "Empty Nest" syndrome of 24-day boxes
Have you ever looked at a 24-day calendar on the 25th? It looks sad. It’s a hollowed-out shell of cardboard and torn paper. By adding that 25th door, the calendar remains a "live" part of the decor until the holiday is actually over. It’s a small detail, but for anyone who loves interior styling, it makes a difference.

Tips for choosing the right one this year
Don't just grab the first box you see. There’s a lot of junk out there. Some brands use the "25th day" as an excuse to throw in a cheap sticker or a plastic keychain while hiking the price up by $20.
- Check the "Total Value" vs. "MSRP": Luxury calendars often claim a value of $1,000 but sell for $250. Look at the specific 25th-day item. If it isn't a full-sized product or a limited edition, the brand might be cutting corners.
- Sustainability: These boxes are huge. Look for brands like L'Occitane or Rituals that offer "refill" versions where you keep the 25-day fabric or wooden structure and just buy the contents the following year.
- The "Early Bird" Trap: The best 25 day advent calendar options—especially in the gaming and hobby space like Games Workshop or Funko—usually sell out by mid-October. If you’re searching for one in December, you’re basically fighting for leftovers.
Finding the "hidden" 25th day
Interestingly, some brands play a game of hide-and-seek. They’ll market a "24-day" box, but then include a "hidden" drawer or a separate envelope for Christmas Day. This is a clever way to manage shipping dimensions while still giving the customer that extra hit of joy.
I’ve seen this recently with indie tea companies. You get 24 days of loose-leaf blends, and then a special "Christmas Morning" blend tucked into the lid. It’s a great way to handle the logistics without making the box too bulky.
Actionable steps for your holiday countdown
If you're looking to upgrade your December routine, here's how to actually handle the 25-day transition without overspending or ending up with a pile of clutter.
- Verify the contents list: Most retailers (even high-end ones like Selfridges) will post a full "spoiler" list on their website. Read it. Make sure the 25th-day item is something you’ll actually use. If it's just "festive confetti," skip it.
- Set a daily time: The best way to enjoy a 25 day advent calendar is consistency. Whether it's 7:00 AM with your coffee or right before bed, make that 25-day streak a "me-time" ritual.
- Repurpose the packaging: High-end 25-day boxes are essentially small pieces of furniture. Don't throw them out. They make excellent organizers for jewelry, office supplies, or even hardware in a garage.
- DIY your own 25th day: If you found a 24-day calendar you absolutely love (like the classic Lindt or a specific toy brand), just buy a small, separate "special" gift and label it "Day 25." You get the calendar you want plus the finale you deserve.
The shift toward the 25 day advent calendar isn't just a marketing ploy. It's a recognition that the holiday doesn't stop when the clock strikes midnight on the 24th. It’s about making sure the biggest day of the year has its own dedicated moment of surprise.
