Six key facts about Advent calendars, one pattern: most commercial versions follow a December 1–24 countdown, while the liturgical season varies each year.

The implication: Advent calendars have split into two distinct streams — one religious and timed to the liturgical season, the other commercial and fixed to December 1.

What is an advent calendar used for?

Counting the days of Advent

An Advent calendar is a countdown device used to mark the days until Christmas. Most versions start on December 1 and end on December 24 (Encyclopaedia Britannica). The term “Advent” comes from the Latin adventus, meaning “coming,” and in Western churches it begins on the Sunday nearest to November 30 (Encyclopaedia Britannica). The practice originated in 19th-century German Lutheran homes, where families used chalk marks, candles, or devotional images to track the days (Encyclopaedia Britannica).

The pattern: the calendar’s fixed start date often conflicts with the movable liturgical season, creating two parallel countdown traditions.

Secular vs religious use

Today, Advent calendars are often seen as secular holiday items, though they remain rooted in Christian tradition (Encyclopaedia Britannica). Religious calendars include Bible verses, Nativity scenes, or small crosses, while secular versions focus on treats. The four weeks of Advent are commonly associated with hope, peace, joy, and love (BibleProject).

The pattern: most commercial calendars have detached from the religious calendar, creating two parallel traditions.

What is in an advent calendar?

Chocolate and sweets

The classic filling: a small piece of chocolate behind each door. Chocolate Advent calendars became widely popular after the mid-20th century (Wentworth Puzzles). Brands like Cadbury, Lindt, and Kinder produce millions each year.

Beauty and makeup samples

Beauty Advent calendars exploded in the 2010s, offering miniature skincare, makeup, and perfume samples. Retailers like Boots and Notino now sell calendars valued at over €200 (Encyclopaedia Britannica). These typically run from December 1 to 24 and contain a mix of best-sellers and exclusive products.

Liquor and adult items

Adult-themed calendars filled with miniature bottles of whiskey, wine, or craft beer have gained traction. Some also contain lingerie, tools, or gourmet snacks. The market has expanded to include calendars for pets, with dog treats behind each door.

Toys and trinkets

Children’s calendars often include Lego sets, Hot Wheels cars, or small figurines. Lego’s Advent calendars are among the best-selling toy calendars globally. According to Christmas Central, many families now prefer reusable calendars filled with their own chosen treats.

Religious verses and images

Religious Advent calendars remain popular in churches and Catholic households. They typically include a Bible verse for each day, often tied to the four-week devotional structure of hope, peace, joy, and love (BibleProject).

The implication: the range of fillings has turned the Advent calendar into a personalized experience, with options for every age, budget, and belief system.

What are the rules of an advent calendar?

Open one door per day

The traditional rule: open exactly one door each day, starting with door number 1. Skipping ahead or peeking is often discouraged by parents. There is no formal rule book, but the custom is consistent across most families (Encyclopaedia Britannica).

Start on December 1 or first Sunday of Advent

Most commercial calendars begin on December 1. However, traditional Advent calendars that follow the liturgical season start on Advent Sunday, which can fall between November 27 and December 3 (Christmas Central). The earliest possible Advent Sunday is November 27 (Wentworth Puzzles).

No skipping or peeking

There is no universal enforcement, but many families treat the daily door opening as a ritual that builds anticipation. The only strict rule is that the calendar should be used as a countdown — not opened all at once.

The catch: the “rules” are largely invented by families, which is why start-date confusion is so common.

Do I start my Advent calendar on 1 or 24?

December 1 start

The vast majority of store-bought Advent calendars — from chocolate to beauty — use December 1 as the first day. The 24th door is opened on December 24 (Christmas Eve). This matches the modern commercial default (Encyclopaedia Britannica).

First Sunday of Advent start

Religious calendars that follow the liturgical year begin on Advent Sunday. Because Advent can start as early as November 27 or as late as December 3, these calendars have a variable number of doors — sometimes 22, sometimes up to 28 (Christmas Central).

The pattern: if you buy a calendar labeled “December 1–24,” start on the 1st. If it says “Advent calendar” without a fixed date, check the first Advent Sunday for the correct start.

What is the best advent calendar to buy?

Chocolate advent calendars

For children and traditionalists, chocolate calendars from Lindt, Cadbury, or Kinder are reliable choices. Prices range from €5 to €20. They are widely available in supermarkets across Europe.

Beauty advent calendars

Luxury beauty calendars from brands like Charlotte Tilbury, Liberty, and Boots offer high-value samples. They often sell out before December. Expect to pay between €100 and €300 (Encyclopaedia Britannica).

Lego and toy calendars

Lego Advent calendars are aimed at children and hobbyists, with a new mini-build each day. Other popular toy calendars include Hot Wheels and Playmobil. Prices range from €25 to €50.

Personalised calendars

Reusable wooden or fabric calendars allow you to fill the drawers or pockets with your own items. Companies like Vistaprint and Etsy shops offer custom dates and themes. These can be more expensive but last for years.

The trade-off: price and personalization are inversely related — custom reusable calendars cost more upfront but save money over multiple years.

Advent calendar timeline

• 1902: Gerhard Lang produces the first printed Advent calendar in Munich (Lignoma).
• 1930s: Commercial calendars with small chocolate pieces appear (Encyclopaedia Britannica).
• 1946: Production resumes after World War II; Richard Sellmer leads revival (Encyclopaedia Britannica).
• 2000s: Beauty and luxury Advent calendars emerge as major product categories (Encyclopaedia Britannica).

The pattern: each wave of innovation moved the calendar further from its religious origins and deeper into consumer culture.

What experts say

“Advent calendars are typically used to count down the days leading up to Christmas, most often starting on December 1 and ending on December 24 or 25.”

— Encyclopaedia Britannica

“Advent as a liturgical season is commonly traced by scholars to the 4th century as a time of preparation for baptism around Epiphany.”

— Christmas Central

The implication: the split between secular and religious calendars is not a modern invention but a pattern that began when the first printed calendar fixed the start date to December 1.

Advent calendar: the real takeaway

The Advent calendar has evolved from a chalk mark on a German wall to a global industry worth billions. Whether you open a chocolate door or a luxury perfume bottle, the practice still revolves around anticipation — counting down to a specific day. For families deciding between a traditional religious calendar and a luxury beauty version, the choice comes down to what kind of anticipation they want to build: one rooted in spiritual preparation or one centered on daily indulgence.
