Early texts claim Jesus was conceived on the same date of his death

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.

The season celebrates Jesus' birth and anticipates the Second Coming of Christ

The Christian Bible’s New Testament features four gospels, or lives of Jesus, each of which describes the birth of Jesus in different ways (or does not mention it). Historians, both secular and religious, have sought to contextualize the biblical accounts with empirical evidence.

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.

Theologians describe how Jesus likely aligned his death with the Passover

Jon Collins and Tim Mackie trace how the Last Supper, the temple confrontation, and the crucifixion each map onto the story of the Exodus, making Easter the culmination of a cosmic liberation narrative begun in Egypt.

The idea of resurrection was not common at the time of Jesus' death

NT Wright, a leading New Testament scholar, argues that first-century Jews held a wide spectrum of beliefs about the afterlife. This included that the early Christian claim of one individual rising bodily from the dead, ahead of the general resurrection, was without precedent in Judaism or the wider Greco-Roman world.

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.

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 earliest depiction of Jesus' crucifixion

The Alexamenos Graffito is widely considered the oldest surviving image of the crucifixion. It was scratched into a plaster wall near Rome's Palatine Hill, probably around 200 CE. It is not devotional art—it shows a donkey-headed figure on a cross alongside the Greek inscription "Alexamenos worships his god," apparently drawn by a student mocking a classmate's Christian faith. No devotional depiction of the crucifixion would be made until the sixth century.

Early Christians viewed the Resurrection as a political claim about authority

Titles like "Son of God," "Lord," and "Savior" were in active circulation as official imperial titles at the time, stamped on Roman coins and carved into public inscriptions about Caesar. Early Christians applied those same words to Jesus, a crucified Jew, as a counter-claim about who actually held authority over the world. (Romans who refused to say "Caesar is Lord" were executed for it.)

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.

Why Easter's date changes, making it a 'moveable feast'

Unlike Christmas, Easter has no fixed date: It falls on the first Sunday after the first full moon on or after March 21, a formula set by the Council of Nicaea in 325 CE to form a standard across Christianity. The result is a window of 35 possible dates, from March 22 to April 25.

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 American colonies recognized New Year’s Eve in March until 1752

England followed the Julian calendar, established by Julius Caesar, which had an inaccurate method of calculating leap years. Because of that, New Year’s Day eventually slipped into the spring and was linked with the Christian festival of the Annunciation, which was on March 25. That date carried over to the American colonies, which didn’t change the first day of the new year until 1752, after England adopted the newer Gregorian calendar.

The dark origins of Valentine's Day.

The holiday began as a feast to celebrate the decapitation of a third-century Christian martyr, or perhaps two. So how did it become all about love?

A look at whether the Last Supper was a Passover Seder meal

Three of the four Gospels describe the Last Supper as a Passover meal, and scholars have cataloged more than a dozen parallels: wine, broken bread, sung hymns, and reclining at the table. But most historians of early Judaism now note that the formal Passover Seder didn't exist as a codified ritual until after 70 CE, decades after Jesus died.

Some believe Valentine's Day evolved from the Roman holiday Lupercalia

The festival, which took place in mid-February, featured Roman priests sacrificing a goat and using its hide to lightly slap women and the land, believing it would bring fertility. Some believe that the Catholic Church repurposed the pagan holiday as a Christian one by attaching it to a saint, but scholars are not certain that this is true.

The claims that Jesus was buried in the Shroud of Turin, preserved since 1578

The 14-foot linen cloth bears a faint image of a crucified man and is the most scientifically studied relic in history. The core dispute hasn't moved much: 1988 radiocarbon dating placed it in the 13th-14th century, while defenders argue the sample was contaminated by medieval repairs. No one disputes that scientists can't explain how the image was formed, which acts like a photographic negative and has no trace of paint or dye.

The prominent role of women in the Easter story

In the first century, women's testimony was not legally admissible in Jewish courts—the historian Josephus wrote that their accounts were not admissible based on a prejudiced view of women. Scholars who argue for the historical reliability of the resurrection point to this as counterintuitive evidence: no one fabricating the story would have chosen women as the prime witnesses.

How Eastern Orthodox and other Christians celebrate Easter differently

Western churches switched to the Gregorian calendar in 1582, though the Orthodox Church still calculates Easter using the Julian calendar, which runs 13 days behind. Orthodox Easter also must always follow Jewish Passover. The result is two Easters that can fall up to five weeks apart.

The history of the New Year's misunderstanding in England

In the mid-18th century, the legal system in England operated under the understanding that the New Year began March 25. However, the widespread custom remained a Jan. 1 celebration as the public had been practicing for years. Read along to discover the practical issues this discrepancy caused and how the English legal system ended up yielding to public belief.

The ancient Greeks and Romans viewed comets and meteors as divine omens

Both considered the appearance of a comet or its fragments as a precursor to significant events, such as the birth of a notable figure or the death of a ruler. One observed in 44 BCE was believed to be a sign of the deification of Julius Caesar after his assassination.

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”).

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 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.

The accounts of the Resurrection from each of the four Gospels

All four Gospels agree that the tomb was empty and that Jesus appeared to followers—but they diverge on many secondary details: how many women came, at what hour, how many angels were present, and in what order Jesus appeared to whom. Historians often see those divergences as a sign of independent accounts rather than coordinated fabrication.

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.

What happened during the 'harrowing of hell'

According to theologians, Jesus descended into the realm of the dead between his crucifixion and resurrection. He did this to liberate the "righteous" who died before him, including Adam and Eve. The belief draws on 1 Peter 3:18-20 and the Apostle's Creed phrase "he descended into hell," and is especially vivid in Eastern Orthodox theology and iconography.

A baby's due date is calculated from the first day of the last menstrual period—not when sexual intercourse occurred.

January is named after Janus, the Roman god of transitions

In 46 BCE, Julius Caesar introduced the Julian calendar, which established Jan. 1 as the beginning of the new year. The month was named after Janus, the Roman god of transitions, who had two faces—one looking back at the past, the other forward to the future. While the Babylonians also made promises as part of their celebration of the new year, the Roman tradition became more focused on looking backwards to plan for the coming year.

Christians believe Jesus was resurrected, body and all

The Christian doctrine of bodily resurrection—that Jesus rose physically, not as a ghost or spirit, and that believers will do the same at the end of time—was found absurd by ancient Greeks. Plato preferred a disembodied soul escaping the body. Paul, on the other hand, staked the entire faith on it. Theologians describe the resurrected body as the same body, but as a transformed one.

El Niño, Spanish for 'the boy,' was named after Jesus Christ because the phenomenon resembled the weather changes observed around Christmastime.

The tradition of drinking Champagne on New Year's is believed to come from ancient Rome

Julius Caesar might not have had sparkling wine, but when the Romans created the now-standard calendar that begins on Jan. 1, they celebrated with a toast. The tradition spread throughout Europe and then the colonies, and so when Champagne became the drink of choice for special occasions, it was only natural that it became the standard New Year’s Eve sip.

The solstice has been celebrated globally for millennia.

Father Christmas was originally associated with decadent parties

The English figure of Father Christmas is another component of the character that would become Santa Claus. Father Christmas was depicted as eating and drinking to excess until the more austere Victorian era. He morphed into a figure dedicated to children and charity, eventually blending into the modern Santa Claus.

The ancient Roman origins of the leap year

The earth's orbit around the sun takes about 365.2422 days, leaving farmer almanacs the awful job of pretending the calendar year fits into a whole number. This article explores the modern origins of the civil solar calendar and its leap year. The Julian calendar, named after the Roman emperor Julius Caesar, cut the calendar year into 365.25 days, gifting the public an extra day every four years. Learn more of the history here.

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.

How 'O Come, O Come, Emmanuel' became a beloved, haunting Advent hymn

The text of the hymn is rooted in the ancient O Antiphons. The melancholic melody was traced to an anonymous 15th-century author. The hymn stands as one of the few standard Christmas carols actually intended to be sung during the season of Advent. Listen to the song's history here.

The winter solstice has been celebrated globally for millennia

From gatherings at Stonehenge in the UK to celebrations of the triumph of Mithra in Iran, cultures around the world have marked the shortest day of the year in a variety of ways for a very long time. Here are eight known to us today that endure.

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.

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.

Documented proof of Shakespeare’s life

Birth in 1564 in the small town of Stratford-upon-Avon; marriage to Anne Hathaway in 1582; and the appearance of his first born (1583) and first printed play (1594): If you’ve ever doubted the Bard’s existence, here are his life’s milestones backed by historical documents.

Mardi Gras blends pagan celebrations with Christian traditions

The holiday has its roots in pagan celebrations, like ancient Rome's Saturnalian and Lupercalian festivals, which celebrated spring and fertility. Rather than abandoning these traditions, Catholic leaders in Rome incorporated their spirit into a celebration that would expel citizens' debauchery in preparation for the sacrifices they'd endure during the Lenten season. Around the world, this holiday season is called Carnival, though the New Orleans version is usually called Mardi Gras.

The names of the 12 months are (mostly) derived from the Romans

January is named after two-faced Janus, February stems from a festival known as Februa, March comes from the god of war, Mars, and so on. Learn the origins and see ancient statues or art for the inspiration for each name of the month.

Alexander Hamilton's birth year is still disputed

Although Hamilton claimed a 1757 birth, records, newspaper accounts, and later biographers suggest his actual birth year was 1755, leaving historians unsure of his true age when he arrived in America.

Why Christians eat fish on Fridays during Lent

The rule isn't actually to eat fish—it's to abstain from eating warm-blooded animals on Fridays, the day of the crucifixion. Fish filled the gap because it was cheap, plentiful, and theologically convenient. As it happens, the medieval Catholic calendar's proliferation of meatless days became one of the drivers of the global fishing industry.

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.

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.

Santa Claus is the result of centuries of evolving traditions

Originating from Saint Nicholas, a 4th-century bishop celebrated for his generosity, Santa's story merged with European folk legends like Sinterklaas and Father Christmas. By the 1800s, American culture redefined him, thanks to Clement Clarke Moore’s poem "'Twas the Night Before Christmas" and Thomas Nast’s illustrations.

Valentine's Day's namesake is unclear

Valentine, which means "powerful" or "worthy," was a popular name in the Roman Empire. Considering that, it's no surprise that there's more than one St. Valentine. In fact, three different men named Valentine were martyred on February 14, and none of them, despite some unproven legends, were ever associated with love or romance.

New Year's Eve celebrations date back to ancient Babylon

Rather than celebrating in winter, the Babylonians honored the vernal equinox, a day in late March with equal amounts of darkness and light that signaled the start of a new year. They celebrated with Akitu, an 11-day festival.
