One of the earliest Advent practices came as a response to a heretical movement

The earliest Advent was a Lent-like fast beginning Nov. 11

In 490, Bishop Perpetuus of Tours ordered Christians to fast three days a week from St. Martin’s Day (Nov. 11) until Christmas. This 40-day season—called St. Martin’s Lent—is one of the earliest documented forms of Advent.

Early European observance varied between penitential and celebratory seasons

For centuries, churches disagreed over the purpose of Advent: Gaul and Spain treated it as a long, penitential fast beginning on November 11, while Rome observed a shorter, more joyful season. These competing traditions were only blended into a unified Advent in the Middle Ages.

Advent originally had almost nothing to do with the Christmas story

Early Advent wasn’t about celebrating Jesus’s birth. In the 5th and 6th centuries, the season focused almost entirely on preparing for Christ’s Second Coming and “final judgment.” Advent’s connection to the Nativity only emerged centuries later.

Some Christian communities start Advent six weeks before Christmas instead of four

While most Western churches begin Advent on the fourth Sunday before Christmas, the Ambrosian Rite (northern Italy) and the Mozarabic Rite (Spain) begin six Sundays before Christmas.

Advent marks the beginning of the church calendar in Western Christianity

Each denomination’s calendar of holy days varies, but most mark the start of a new year at the beginning of Advent. Within Roman Catholicism, Advent is a distinct period from Christmas, alongside other seasons: Ordinary Time, Lent, Easter, Holy Week, and Pentecost.

Martin Luther is often cited as the first to decorate the Christmas tree—though the practice began decades earlier

Saturnalia was a Roman festival that helped shape Christmas

Ancient Romans celebrated Saturnalia in mid-December, honoring Saturn, the god of agriculture, with week-long street festivals. These celebrations featured gift exchanges, lavish meals, and gambling, which was prohibited in public at the time.

The first printed Advent calendars were from Germany in the early 1900s

Printed Advent calendars originated in early-20th-century Germany, where printer Gerhard Lang created the first commercially produced versions. Inspired by his mother’s homemade countdowns, Lang added small doors in the 1920s, establishing the format that spread worldwide.

The Quartodeciman controversy debated what day to celebrate Easter in the early church

Asian churches marked Easter on the 14th day of the Hebrew month of Nisan (roughly March-April), while Roman churches insisted on Sunday. Polycarp of Smyrna, an associate of the Apostle John (who tradition says wrote one of the four Gospels) traveled to Rome to advocate for the 14th of Nisan. The Nicene Council decided that celebrating on a Sunday would ensure Christian unity and distinguish the observance from Jewish passover.

Christmas celebrates the anniversary of God's birth as the man Jesus

The major holiday originated in the Christian doctrine of God's incarnation in first-century Roman Judea. Though it was not celebrated for several hundred years after Jesus' death, it took on greater importance as the church spread, culminating in a global holiday season today.

Christmas was briefly banned in 17th-century England

In the 1640s, Puritans outlawed Christmas, deeming it wasteful and unbiblical. For nearly two decades, celebrations were suppressed and violators fined, though many ignored the ban. The law was repealed in 1660.

Mall Santas became a widespread tradition beginning in the 1900s

Christmas carols began as communal folk songs in medieval Europe, and were later adapted into religious hymns. Revived in England in the 19th century, they have become a core holiday tradition around the world.

The Stations of the Cross reenact Jesus' 'passion,' or suffering

The practice originated with early Christian pilgrims walking the Via Dolorosa—the path Jesus likely look as he walked with his cross to the site of his crucifixion—in Jerusalem and took root in European churches in the fifth century CE as a devotion for those who couldn't travel to the Holy Land. Pope Clement XII fixed the number of stations at 14 in 1731; five of them are based entirely on tradition, rather than scripture.

Traditionally, a glut of unused eggs during Lent would be decorated at Easter

Revisiting the ornamental hermit craze of the 1700s

One of the more elaborate gardening trends of the 18th century was the placement of a well-designed hermitage within the landscape, a throwback to the more religious antiquity and the Middle Ages.
