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.

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.

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.

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.

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.

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.

What is Good Friday, and why is it called 'good'?

Good Friday commemorates the crucifixion of Jesus, the darkest moment in the Christian story (which makes the name a genuine puzzle). Typical explanations say "good" once meant "holy" or "sacred," while other traditions dub it "sorrowful Friday." Christians observe rather than celebrate the day, with services, fasting, and quiet. It's always two days before Easter, sitting between Maundy (or Holy) Thursday and Easter.
