Christmas is the most wonderful time of year for many people. It brings together a religious story, old folk customs, family traditions, and the modern consumer world. But when we take a closer look at Christmas “under the hood,” we find that many things we take for granted have a surprising history—and often aren’t nearly as old as we might expect.
The following 24 facts will show Christmas from a slightly different angle—from the holiday’s origins, to traditions in Slovakia, to modern customs that have appeared only recently.
1. Christmas wasn’t originally the “main” Christian holiday
Today, Christmas—along with Easter—is among the most important Christian holidays, and December 25 is celebrated in most Christian churches. In the first centuries of Christianity, however, believers emphasized Jesus’ death and resurrection more than his birth. The celebration of Christ’s birth took shape only gradually, and for a long time it was linked with other feasts—for example, the Feast of the Epiphany on January 6.
Only later did Christmas become a separate feast in its own right and take the place in the liturgical calendar that we now consider self-evident.
2. We don’t know the exact date of Jesus’ birth
The Bible does not give a specific date for Jesus’ birth. The fact that Christmas is celebrated on December 25 is the result of a Church decision and theological reflection, not a historically documented date. According to historians, the celebration of Christ’s birth on December 25 in Rome began only in the 4th century, around the year 336, during the reign of Emperor Constantine.
Some interpretations link this date to the symbolism of the winter solstice and the adoption of the pagan festival of the “Unconquered Sun,” while others connect it to calculations suggesting Jesus was conceived in spring and born at the end of the year. The only certainty is that December 25 is a liturgical date, not a historically verified one.
3. Jesus was probably born “before Christ”
It sounds paradoxical, but according to more recent historical and biblical research, Jesus may have been born roughly 4 to 7 years “before Christ.” The reason is that the monk Dionysius Exiguus, when calculating our calendar era in the 6th century, likely miscounted by a few years when dating the reign of King Herod and other historical events.
So Christmas each year commemorates an event whose exact year and day we don’t know. That doesn’t bother believers—more important than historical details is the theological and spiritual meaning of Christ’s birth.
4. Why December 25? The sun, the solstice, and the symbol of the “Light of the World”
One explanation for choosing December 25 is connected with the Roman festival Natalis Solis Invicti—the feast of the “Unconquered Sun,” celebrated around the winter solstice. Some historians believe Christians adopted this symbolism and “filled” it with new meaning: Christ as the “Sun of righteousness” and the “Light of the World.”
Another theory says Christians assumed Jesus was conceived on the day of the spring equinox and born nine months later—at the end of December. In any case, the choice of date is primarily symbolic, not based on a historical record.
5. The Slovak word “Vianoce” is likely related to the German “Weihnachten”
The Slovak word Vianoce is fairly distinctive in a European context. Most languages use a name derived from Christ (Christmas, Noël) or from “birth” (Navidad, Natale). Linguists generally agree that our Vianoce is related to the historical German word Weihnachten—“holy night,” or “holy nights.”
There are alternative theories (for example, an Old Slavic “great day”), but the best-attested origin is the Germanic one combining “holy” and “nights.” Interestingly, while in Slovak it is a plural noun (Vianoce), in other languages it is often singular.
6. In Slovakia, Christmas has more than one name
Alongside the word Vianoce, other names have been used in Slovakia, and in some places still are: kračún, hody, or simply the Nativity (of the Lord). In some regions, people still say they’re “going to Kračún” or “to Hody,” meaning the Christmas holidays.
These names recall older layers of tradition and show that for our ancestors, Christmas was closely tied to folk religiosity, feasting, family gatherings, and also to magical rituals meant to ensure health, a good harvest, and protection for the home.
7. In Slovakia, the centerpiece of Christmas is December 24 rather than the 25th
In the official Church calendar, the main feast is December 25—Christmas Day. In many countries (for example, the U.S. or the U.K.), gifts are opened only then. In Slovakia, however, the emotional peak of Christmas is Christmas Eve, December 24—especially the Christmas Eve dinner.
Traditionally, gifts are unwrapped right after dinner, not in the morning, and many families see this date as “the real Christmas.” A similar pattern can be found in other Central European countries, such as the Czech Republic, Austria, and Germany.
8. Advent—quiet preparation that is older than Christmas itself
The four Advent Sundays before Christmas form a season of preparation, fasting, and quiet reflection. Advent has been known in the Church since the earliest centuries, although its length and form varied by region. Today, it is associated mainly with the Advent wreath with four candles and the Advent calendar.
In the modern world, Advent has also become a marketing term—“Advent sales,” “Advent giveaways,” or “Advent markets.” The original idea, however, points more toward slowing down, spiritual preparation, and the gradual “lighting” of the light that culminates at Christmas.
9. The Advent calendar originated in Germany—and now has a digital form
The first Advent calendars appeared in German-speaking countries in the 19th century. Parents used crosses, pictures, or candles to show children how many days were left until Christmas. Later came cardboard calendars with little windows and sweets, which spread across Europe.
Today there are Advent calendars with chocolate, cosmetics, tea, and even small electronics or toys. In the digital age, online and gaming calendars have emerged that “unlock” new content each day—from videos to mini-games—making the wait for Christmas more fun for both children and adults.
10. The first documented Christmas tree stood on the Baltic Sea
The modern Christmas tree as we know it developed in Central Europe, especially in Germany and in the area of present-day Estonia and Latvia. National Geographic notes that these two countries still “argue” about where the first documented tree stood—Riga cites the year 1510, while Tallinn points to a similar tradition as early as 1441.
The tree was originally decorated with apples, wafers, nuts, and handmade paper ornaments. Candles appeared later, bringing not only the charm of light but also a fire risk—so in the 19th century the first electric lights began to be used.
11. The Christmas tree reached Slovakia only at the end of the 18th century
In Slovakia, the Christmas tree became established later than in German-speaking lands. According to historians, it arrived from Germany and Austria at the end of the 18th century—first in towns and middle-class households, and only later in the countryside.
An interesting detail is that in the past the tree was often not placed on the floor but hung from the ceiling—“upside down,” with the tip pointing toward the ground. This saved space in small rooms and also carried symbolic meaning: abundance “descends” on the family from above. In some regions, this custom is still mentioned in grandparents’ memories.
12. Real vs. artificial trees: the ecological dilemma isn’t that simple
Many people believe an artificial tree is more eco-friendly because it can be used for many years. Experts, however, point out that producing a plastic tree has its own environmental footprint, and to “break even” compared to a real tree, you have to use it for a long time. With naturally grown trees from dedicated plantations, the argument is that they absorb CO₂ while growing and are often grown on land unsuitable for agriculture.
That’s why many families choose a compromise: a small living tree in a pot that can be planted after the holidays, or at least a preference for local growers. Christmas can be a bit kinder to nature—without giving up the scent of pine needles.
13. Baby Jesus, Santa, Father Frost… who brings the gifts?
In Slovakia, gifts are traditionally brought by Ježiško (the “Baby Jesus”), a more symbolic figure than a literal “child in the manger.” In neighboring Czechia it’s similar, while in many Western countries Santa Claus arrives—a figure shaped by Saint Nicholas, 20th-century marketing, and American culture.
In Finland they have Joulupukki; in Scandinavia, gnomes and elves; in parts of Spain, gifts are brought by the Three Kings. Another interesting point is that in the former Soviet Union and in some post-Soviet countries, Father Frost (Ded Moroz) was more prominent than Christmas, and gifts were associated more with New Year’s than with the birth of Christ.
14. Christmas Eve dinner in Slovakia used to be more modest and meatless
Today, many people can’t imagine Christmas Eve without fried carp or schnitzel and a lavish table. But historical sources and ethnographic research show that the traditional Christmas Eve meal was more of a fast—simple and meatless: cabbage soup, pea or mushroom soup, various porridges, baked potatoes, and bread.
Carp as the “main star” of Christmas Eve spread only in the 20th century. More luxurious meat dishes were the exception and reflected a family’s social standing. Still, it was important that there be “enough food for everyone to eat their fill, with some left over”—a symbol of abundance for the coming year.
15. Slovak Christmas customs: a chain under the table, straw, nuts, and apples
In the past, objects with a magical or protective meaning were placed on or around the Christmas Eve table. A chain wrapped around the table symbolized family unity—so the family would “stick together.” Straw under the table recalled the Bethlehem manger and was also meant to ensure a good harvest and healthy livestock.
Cutting an apple crosswise showed whether the family would be healthy (a nice star shape meant a good year). Nuts thrown into corners were meant to protect the house and all living things. Fortune-telling with walnut shells, keeping carp scales in a wallet, or the “first visitor” after midnight are just a small sample of the richness of Slovak Christmas traditions.
16. Christmas baking is almost a “national sport” in Slovakia
Slovaks are among the nations where homemade Christmas baking is especially widespread. The scent of gingerbread, Linzer cookies, and walnut and poppy-seed pastries fills many homes days before Christmas Eve.
Traditional recipes are passed down from generation to generation, and there is often a “family version” you won’t find in any cookbook. Interestingly, gingerbread used to be commonly hung on the Christmas tree as decorations—so the tree was not only beautiful but also edible.
17. The carol “Silent Night” was born in a small Austrian village
One of the most famous Christmas songs in the world is “Silent Night” (Stille Nacht), first sung at Midnight Mass in 1818 in the Austrian village of Oberndorf near Salzburg. The lyrics were written by the priest Joseph Mohr, and the melody was composed by the teacher and organist Franz Xaver Gruber.
The song quickly spread across Europe and later around the world. It has been translated into dozens of languages, and in 2011 Austria added it to UNESCO’s list of Intangible Cultural Heritage. Today, believers and non-believers alike hum it—and during Christmas, few people go without hearing its melody at least once.
18. The Nativity scene as “live theater” has medieval roots
The depiction of the manger with Jesus, Mary, Joseph, shepherds, and animals has a long tradition. According to historians, the first “living Nativity” was created by Saint Francis of Assisi in 1223, when he wanted to bring the story of Christ’s birth vividly closer to people.
Later, Nativity scenes began to be made in wood, paper, or ceramic form and gradually became a common part of churches and homes. Slovakia has a rich Nativity-making tradition, especially in folk culture—from simple wooden mangers to large moving Nativity displays with dozens of figurines.
19. Christmas markets began in German towns—today they’re a tourist magnet
A typical European Christmas atmosphere also includes Christmas markets. Their predecessors appeared as early as the Middle Ages in German and Austrian cities, where craftsmen and merchants offered goods ahead of winter. Over time, they became specialized pre-Christmas markets with food, drinks, gifts, and cultural programs.
Today, many Slovak towns can’t imagine Advent without them. Besides punch and mulled wine, they also have an economic dimension: for local entrepreneurs and municipalities, they are an important part of the pre-Christmas season, during which people spend billions of euros on food, drinks, and gifts.
20. The Eastern and Western Churches don’t always celebrate Christmas on the same day
While in most countries of the Western tradition (Roman Catholic and Protestant churches) Christmas is celebrated on December 25 according to the Gregorian calendar, many Orthodox churches use the older Julian calendar for liturgical feasts.
That’s why, for example, in Russia, Serbia, or in some parts of Ukraine, “their” Christmas Eve falls on January 6 and Christmas on January 7. For tourists and people living abroad, it can be an interesting experience—celebrating Christmas twice, according to “two calendars.”
21. Christmas is not only a religious holiday, but also a deeply family and cultural one
Even people who don’t identify with faith often celebrate Christmas as a holiday of family, peace, and togetherness. Sociological surveys show that in Europe and North America, most of the population celebrates Christmas, even though some do not perceive its religious dimension.(Wikipedia)
That’s why Christmas is also a cultural phenomenon: it influences music, film, literature, advertising, and even the look of cities and homes. Christmas “classics”—from fairy tales to romantic movies—have become part of family rituals just as much as Christmas Eve dinner or decorating the tree.
22. Christmas and charity: the holiday is also about sharing with others
Before Christmas, charities, food banks, and various fundraising drives become much more active. People think more about those who have no family, no housing, or not enough food. Many families have created their own tradition—for example, packing a gift parcel for children in need, donating to charity instead of buying yet another unnecessary present, or going to help at a shelter.
This side of Christmas recalls the original meaning of a gift: it doesn’t matter whether it costs €5 or €50, but that it is a sign of attention and care. For children, taking part in such activities can be a powerful lesson in empathy and solidarity.
23. Christmas has a “digital” side, too
Where carolers once went in person from house to house, today we also have Christmas emails, messages in chat apps, video calls, and online greetings. For families scattered around the world, modern technology is often the only way to “meet” at Christmas—see each other and sing carols together, at least through a screen.
The digital age has also brought new traditions: watching Christmas movies together via streaming services, online concerts, virtual caroling, or even “digital Nativity scenes.” For some, it’s a loss of “magic”; for others, it’s a way to stay connected with loved ones who are far away.
24. Christmas lasts longer than most people think
Many people see Christmas as a three-day block from December 24 to 26. In Christian tradition, however, the Christmas season lasts longer—in the Catholic Church until the Feast of the Epiphany (Three Kings) on January 6, and in some countries decorations and the tree are taken down only at Candlemas in early February.
In Slovakia, it’s not unusual for the tree to remain in the living room for several weeks after Christmas Eve. It’s a reminder that Christmas isn’t just about one evening and presents, but about a longer period of calm, family gatherings, and a slower pace.
Bonus: A video about the history of Christmas
If you like videos and want to see the history of Christmas in documentary form (in English), you can watch this documentary about the holiday’s development from the early centuries to the present day:
The video nicely complements the facts about why Christmas is celebrated in December, how the best-known traditions arose, and how the holiday changed across different historical periods.
Conclusion
Christmas is a fascinating blend of old pagan symbols, Christian theology, folk customs, and modern consumerism. Many traditions we now consider “ancient” are only a few centuries old, while others, by contrast, reach far back into history.
Perhaps that is the greatest curiosity of all: Christmas is constantly changing and evolving, yet its core remains the same. It’s about light in the midst of darkness, hope in the midst of uncertainty, and the fact that the greatest gift is the people we can spend the holidays with—whether we believe in Ježiško, Santa Claus, or “simply” in the power of family and closeness.
