Lent Explained for Beginners: What It Is and Why It Lasts 40 Days

Maybe a coworker came back from lunch with ash on her forehead. Maybe a friend turned down a burger on a Friday and said, a little sheepishly, "It's Lent."

Lent is one of the oldest seasons in the Christian calendar: a stretch of weeks before Easter set aside for prayer, honesty, and a deliberate slowing down.

What Lent is

Lent is the season of preparation for Easter. It begins on Ash Wednesday and runs through Holy Week, ending as Easter arrives. In mood it is the opposite of a festival. Churches often quieten their worship, sing more reflective music, and read the stories of Jesus moving toward the cross.

Christians who keep Lent describe it as spring cleaning for the inner life: a set period to notice what has grown cluttered, to turn back toward God, and to make room for other people. Repentance runs through the season, and in the biblical sense it means a change of direction, not simply feeling bad.

Lent is observed by Roman Catholics, Eastern Orthodox Christians, and many mainline Protestants, including Anglicans, Lutherans, Methodists, and Presbyterians. Some evangelical Christians keep it too. No single tradition owns it.

Why forty days?

The number comes from the story of Jesus in the wilderness. After his baptism, the Gospels say, Jesus spent forty days fasting and being tested before his public ministry began:

And when he had fasted forty days and forty nights, he was afterward an hungred.

Matthew 4:2 (KJV)

Lent mirrors that journey: Christians take the same span of time to step back from ordinary comforts and pay attention. Forty recurs throughout the Bible, in Israel's forty years in the wilderness and Moses' forty days on the mountain, as a long, testing season that leads somewhere new.

Wait, count the calendar

Count from Ash Wednesday to Easter Sunday and you will get more than forty. In the Western way of counting, Sundays are not counted as days of the Lenten fast.

Every Sunday is a small celebration of the resurrection, a weekly Easter, and therefore not a day of fasting even in a fasting season. Set the Sundays aside and the remaining days from Ash Wednesday through Holy Saturday come to forty.

Eastern Christian practice differs. In the Orthodox tradition the season, often called Great Lent, is counted and structured differently, includes its own preparatory weeks, and its fasting discipline is generally stricter, traditionally involving abstinence from meat, dairy, and eggs through much of the season.

Ash Wednesday and the ashes

Lent opens with one of the most recognizable services of the year. On Ash Wednesday, many churches mark foreheads with ash, traditionally made by burning the palm branches from the previous year's Palm Sunday. As the ash is applied, the minister often says words drawn from Genesis:

for dust thou art, and unto dust shalt thou return

Genesis 3:19 (KJV)

It sounds stark, and it is meant to be honest rather than frightening. The ashes say, in a way you wear home on your skin, that life is finite and nobody's time is unlimited, and that the weeks ahead are for taking that seriously in a hopeful direction.

The three practices: prayer, fasting, and almsgiving

Traditionally, Lent rests on three practices, meant to work together.

Prayer

Lent invites more prayer, or more honest prayer, than usual: a set time each morning, a psalm a day, a midday pause, or weekday services offered only in this season. The aim is attention, making actual space to listen rather than squeezing faith into an unchanged schedule.

Fasting

Fasting means going without food, or some of it, for a set time or on set days. Roman Catholic practice includes fasting on Ash Wednesday and Good Friday for adults within certain age and health limits, and abstaining from meat on Fridays in Lent, which is why fish appears on so many Friday menus. Orthodox fasting is broader. Many Protestants fast in a simpler, self-chosen way. Anyone with a medical condition, and anyone pregnant, elderly, or very young, is excused from fasting rules in traditions that have them.

Almsgiving

Almsgiving is the traditional word for giving money and help to people in need. It keeps Lent from becoming a private self-improvement project. Money saved by eating more simply is classically given away. So is time: volunteering and checking on an isolated neighbor belong here.

What do people actually give up?

This is the part of Lent most visible from outside. People commonly give up chocolate, alcohol, coffee, social media, or sweets. The choice is supposed to cost a little: giving up something you never use misses the point, which is a small, repeated reminder of the season you are in and the direction you want to turn.

Just as common now is taking something up instead: a daily reading, a gratitude practice, a standing phone call to a lonely relative. Many people do both. For a structured way to read through the season, Faith Map offers seasonal journeys, including Lent reading plans in season, and reading in the app is free. You can explore Lent journeys in Faith Map when the season approaches.

Nobody keeps a perfect Lent. People forget on day three, travel, get invited to birthday dinners, and start again. Starting again is, by most accounts, rather the point.

Holy Week: how Lent ends

The final week of Lent is Holy Week. It begins with Palm Sunday, recalling Jesus entering Jerusalem to cheering crowds, moves through the Last Supper on Maundy Thursday and the crucifixion on Good Friday, and waits in the quiet of Holy Saturday. Then, at Easter, the season breaks open and the fasting gives way to celebration.

A simple way to begin

Begin smaller than your ambitions. Choose one thing to give up that you will genuinely notice, one short daily practice of prayer or reading, and one concrete way to give, of money or time, each week. Expect to slip, and restart without drama. Your faith is beautiful, and seasons like this one exist to help you live it on purpose.
