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

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

In 380 CE, the Council of Saragossa met to oppose the spread of Priscillianism, a local heresy. The council ordered Christians to observe strict church attendance from Dec. 17 to Christmas—one of the earliest documented Advent-like practices.

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 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.

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's length varies from 21 to 28 days each year

Because Advent always begins on the fourth Sunday before Christmas, its duration varies. When Christmas falls on a Monday, Advent is unusually short, and when it falls on a Sunday, it can be nearly four full weeks long.

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.

What is Lent?

Lent is the 40-day period of fasting and penitence before Easter, modeled on Jesus's 40 days of fasting in the wilderness. Rooted in early Christian practice, it was formalized at the Council of Nicaea in 325 CE. Pope Gregory I established Ash Wednesday as its start in 601, creating the season's current structure of 46 days—40 fasting days plus six Sundays, which were traditionally treated as feast days.

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.

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

Luther lore claims he may have been the first to link tree decorations to Jesus, as he used candles to symbolize the Nativity star. However, German bakers had adorned evergreens with apples and sweets as early as 1419 for Christmas Eve displays.

The traditional colors of Advent are purple, rose, and white

Purple is Advent’s primary color, symbolizing preparation and prayer; rose appears on the third Sunday to signal joy; and white, used for the fifth Advent candle or Christmas liturgies, represents purity and celebration as Christmas arrives.

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.

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

That's how the tradition started, at least in the more orthodox (or strict) branches of Christianity, which didn't eat meat, dairy, or eggs the whole period. By the end, there was more than could be eaten, so decorations ensued.

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.

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.

Halloween originated with the Celtic festival of Samhain

Halloween, a holiday primarily popular in the US and Canada, originated 2,000 years ago with the Celtic people.
