What is Lent?

'Mardi Gras' is French for 'Fat Tuesday'

Ash Wednesday, the first day of Lent, requires practicing Catholics to fast. The day before the fast became known as "Fat Tuesday" because it was seen as the last opportunity to indulge before fasting on Ash Wednesday and sacrificing throughout Lent. "Carnival" comes from the Latin for "removal of meat."

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.

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.

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 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.

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 Lunar New Year lasts 15 days, with specific rituals for specific days

On the first night, loved ones gather to celebrate their honor and say goodbye to the successes and tribulations of the old year. On the fourth day, the God of the Kitchen is honored to prevent kitchen accidents. And beginning on day 12, people prepare for the final Festival of Lanterns.

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.

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.

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.

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.

In the 1600s, coffee had religious significance

In the 1600s, coffee was important in multiple religious traditions. In Yemen, it was the drink of choice for Sufi mystics to improve their focus and fuel their grueling meditations. Pope Clement VIII's approval spread coffee’s popularity from the Muslim to the Christian world, paving the way for the cappuccino.

Asia's agriculture-focused set of 24 'small seasons'

In contrast to the four broad seasons and their basis in astronomy and climate, ancient farmers in China and Japan had many more and varied seasons (or "sekki). Take Keichitsu (March 6 to 21), for example: this means "going-out of the worms" when bugs come out from hibernation.

What was the longest year in history?

In 46 BCE, Julius Caesar declared the year would last 445 days. This four-minute podcast and accompanying article explain why. Caesar wanted to make the following year start after the winter solstice, an achievement attainable due to his tinkering with the Roman calendar. But to start the year right, Caesar had to stretch the transitional year, leading to the creation of Caesar's Year of Confusion, the longest year in history.

Reflect on his legacy and how he changed the church in this video.
