The Advent wreath marks each week before Christmas with the lighting of candles

Many Christians observe a different theme for each week of Advent

Many churches structure Advent around weekly themes—often hope, peace, joy, and love—which shape sermons, prayers, Scripture readings, and the lighting of candles on the Advent wreath. The specific themes vary widely across denominations and communities.

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.

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.

See how Advent traditions vary widely around the world

Advent is celebrated in distinct ways across countries—Chinese Christians hang colorful lanterns, Mexicans reenact Las Posadas processions, Germans light weekly wreath candles, and Hungarians attend dawn matins—reflecting how local cultures shape the season’s preparation.

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.

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 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.

Before electric lights, Christmas trees were lit with real candles

The practice of lighting Christmas trees with electricity didn’t begin until the late 1800s. Before that, families used wax candles on branches—a dangerous tradition that originated in 16th-century Germany.

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.

Seven ancient ‘O Antiphons’—names for Jesus—are sung in the days before Christmas

The antiphons are prayers that express a profound longing for Jesus’ return and commemorate His birth. Each of the antiphons (for example, "O Emmanuel," the basis of the classic hymn) ascribes a different name to Jesus, like O Sapientia (“wisdom”) and O Rex Gentium (“king of the nations”).

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.

Rockwell helped define the American Christmas

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.

For the medievals, the moon was a versatile religious symbol

Within the distinct traditions of Christianity and Islam, the moon became a central metaphor and sign for religious teaching. For Christians, its light was used to explain Jesus' humanity with the light of the sun (divinity). For Muslims, the moon represented a cosmic longing for god.
