There is a moment every year when the Orthodox Church changes its face. The services grow longer. The lights are dimmed. The prostrations begin. The ordinary Divine Liturgy disappears on weekdays. The liturgical vestments shift from white and gold to violet and black. And the faithful — at the end of a particularly moving Sunday evening service — bow to the ground before one another and ask each other's forgiveness. This moment is called Clean Monday — and it opens the most intense, richest and most demanding period of the entire Orthodox liturgical year: Great Lent.
Orthodox Great Lent (Velikaya Chetvedeesiatnitsa in Church Slavonic, Megali Tessarakostè in Greek) is far more than a religious dietary practice. It is a forty-day spiritual school — with its own liturgical books, its own weekly themes, its own saints, its own melodies, its own rites. No other period of the year transforms the life of an Orthodox community so profoundly. And no other period prepares more completely for the mystery of Pascha — the Feast of Feasts to which Great Lent leads like a long corridor toward a great light.

Dates of Orthodox Great Lent 2025–2029
Great Lent is a movable observance: its dates change every year according to the date of Orthodox Pascha. It always begins on Clean Monday, seven weeks before Pascha, and ends on Lazarus Saturday, the day before Palm Sunday. Holy Week follows as a distinct but immediately continuous period.
| Year | Clean Monday (start) | Lazarus Saturday (end of Great Lent) | Orthodox Pascha |
|---|---|---|---|
| 2025 | March 3, 2025 | April 12, 2025 | April 20, 2025 |
| 2026 | February 23, 2026 | April 4, 2026 | April 12, 2026 |
| 2027 ← next | February 15, 2027 | April 24, 2027 | May 2, 2027 |

| 2029 | February 19, 2029 | March 31, 2029 | April 8, 2029 |
Churches of the Julian calendar — Russian, Serbian, Georgian, Jerusalem — begin Great Lent on the same relative days in relation to their own Pascha, but these dates generally fall several weeks later in the civil calendar.
The preparation weeks: the Triodion before Lent
One of the great distinctives of Orthodox Great Lent is that it does not begin abruptly. The Church prepares for it over three pre-Lenten weeks, each carrying its own spiritual theme. This preparation period is contained in the Triodion — the liturgical book of Great Lent, one of the most beautiful and theologically rich in the entire Byzantine tradition.
For many Americans encountering Orthodoxy for the first time — whether as converts, inquirers or the non-Orthodox spouses of Orthodox Christians — the pre-Lenten Triodion weeks are a revelation. Western Christianity has Ash Wednesday; Orthodoxy has a three-week spiritual unwinding that begins seven weeks before Pascha. The depth of this preparation is one of the things that most distinguishes Orthodox Lent from anything in the Western Christian tradition.
1st preparation week: the Publican and the Pharisee
The parable of the Publican and the Pharisee (Lk 18:10–14) is proclaimed at the opening Sunday of the Triodion. Its message is the foundation of the entire Lent: humility is the condition of all conversion. The Pharisee fasts and prays — but compares himself to others and congratulates himself. The Publican simply beats his breast saying "God, be merciful to me, a sinner" — and he is the one who goes home justified. The Church says to its faithful, before the fast even begins: beginning Lent in spiritual pride is worse than not beginning it at all.
This week ends with a fast-free week (the Week of the Publican and Pharisee) — a pedagogical paradox: the Church temporarily suspends the usual Wednesday and Friday fast so that the faithful do not fall into the attitude of the Pharisee who is proud of his practice.
2nd preparation week: the Prodigal Son
The parable of the Prodigal Son (Lk 15:11–32) — proclaimed two weeks before Lent — develops the second founding theme: repentance is always possible, and the Father runs to meet us. After the warning against pride (the Pharisee), the Church offers the remedy against despair (the son who has squandered everything but is received in his father's arms). Psalm 137 — "By the waters of Babylon" — is sung for the first time: the cry of exile that will become one of the leitmotifs of Great Lent.
3rd preparation week: Meatfare Sunday
Meatfare Sunday (the Sunday of the Last Judgment) is the last Sunday on which meat is eaten. The Gospel of Matthew 25 (the Last Judgment) reminds us that the measure of our life will be our love for "the least of these" — the hungry, the stranger, the sick, the prisoner. This is the social and ethical anchoring of Lent: the food fast is inseparable from the fast from selfishness. For converts from Protestant or Catholic backgrounds, Meatfare Sunday is often a striking introduction to Orthodox Lent's integrated vision of body, soul and neighbor.
4th preparation week: Cheesefare Week
The final week before Lent is Cheesefare Week (Russian: Maslennitsa; Greek: Apokreo; Romanian: Săptămâna albă). Meat is already forbidden, but dairy products (cheese, butter, eggs) are still permitted — hence the alternate name Cheese Week. It is a time of moderate festivity and gentle transition before the strict fast begins. Forgiveness Sunday closes this week and opens the gates of Great Lent. In American Orthodox parishes, Cheesefare Week often includes pancake breakfasts after Sunday Liturgy — a tradition inherited from the Russian Maslennitsa, adapted warmly to the American parish social calendar and often one of the first glimpses converts get of Orthodox community life at its most joyful.
Forgiveness Sunday and Clean Monday: how Great Lent begins
The transition between Cheesefare Week and Great Lent is one of the most moving and distinctive liturgical moments in the entire Orthodox year — and one that has no parallel anywhere in Western Christianity.
The Rite of Forgiveness
On Sunday evening, at the end of Forgiveness Vespers, a rite unlike anything in Western Christian practice takes place: the rite of mutual reconciliation. The priest descends from the altar, bows to the floor before the faithful and asks their forgiveness. The faithful respond by bowing in turn. Then, in a movement that spreads through the entire assembly, every member of the parish makes a metania (prostration) before every other member and says: "Forgive me" — to which the other responds: "God forgives, and I forgive."
In a large parish this rite can last an hour or more. It is not symbolic — it is real. Parishioners who have argued, ignored or hurt one another over the course of the year stand face to face in this rite. You cannot enter Lent with a closed heart toward your brother or sister. Only after this reconciliation do the vestments change color, the Lenten services begin and the great forty-day spiritual adventure opens. For many converts to Orthodoxy in America, the Forgiveness Vespers service is the single most powerful liturgical experience they encounter in their first year — nothing in their previous Christian experience prepared them for it.
Clean Monday
In Greece, Clean Monday (Kathara Deutera) is a national public holiday — families go to the countryside, fly kites and eat a communal Lenten meal of flatbread, olives, seafood and raw vegetables. In the United States, Clean Monday falls on an ordinary workday, and Orthodox Christians manage the transition more quietly. But in Greek-American parishes — from Tarpon Springs, Florida to Astoria, New York — parish Clean Monday gatherings after the evening service maintain the communal spirit of the day. In some Antiochian and OCA parishes, the evening of Clean Monday is one of the most attended services of the year: the Great Compline with the first canticles of the Great Canon draws faithful who may not otherwise attend weekday services, drawn by the unmistakable atmosphere of a new spiritual beginning.
The five great weeks and their spiritual themes
Great Lent proper (from Clean Monday to Lazarus Saturday) consists of five Lenten weeks. Each Sunday of Great Lent is dedicated to a particular theme or saint — a structure that has no equivalent in Western Lenten observance and that gives Orthodox Lent its distinctive pedagogical architecture.
1st week: the Great Canon and the beginning of the struggle
The first week is the most intense of Great Lent. The services are the longest of the year — some lasting more than four hours. Every evening from Monday through Thursday, the Church sings the Great Canon of Saint Andrew of Crete (see the following section). It is total immersion in the spiritual struggle. Prostrations (metanies) are numerous at every service — full prostrations, forehead to the floor. On Friday evening, the Liturgy of the Presanctified Gifts is celebrated for the first time.
2nd Sunday: Saint Gregory Palamas
The second Sunday honors Saint Gregory Palamas (1296–1359), Archbishop of Thessalonika and theologian of the Uncreated Light. The choice is not incidental: in the middle of Lent, the Church reminds its faithful of the goal of all spiritual effort. Fasting, praying, prostrating — none of it is an end in itself. It is the preparation of the soul to receive the divine light — the same light the Apostles beheld on Mount Tabor at the Transfiguration. Great Lent is not a season of gloomy penance — it is a season of preparation for light. For Orthodox converts from Protestant backgrounds, this theological framing is often transformative: Lent is not primarily about guilt but about vision.
3rd Sunday: the Veneration of the Holy Cross
At the exact midpoint of Great Lent — the third Sunday — the Holy Cross is solemnly carried to the center of the church for the veneration of the faithful. This gesture says two things simultaneously: we are halfway through the fast, and the Cross we are approaching is not a sign of defeat but of victory. The liturgy sings: "Your Cross we venerate, O Master, and Your holy Resurrection we glorify." Pascha and the Cross are inseparable — this is the message at the heart of Lent.
4th Sunday: Saint John Climacus
The fourth Sunday is dedicated to Saint John Climacus (6th century), monk of Sinai and author of The Ladder of Divine Ascent (Klimax in Greek, hence his name). This work of monastic spirituality, organized in thirty rungs corresponding to the thirty years of Christ's hidden life, is one of the most widely read spiritual works in the Orthodox tradition. Its presence at the fourth Sunday recalls that Lent is a progressive ascent — rung by rung — toward God.
5th Sunday: Saint Mary of Egypt
The fifth and final Sunday of Great Lent is dedicated to Saint Mary of Egypt — one of the most radical and most moving figures in the entire Orthodox tradition. A former courtesan from Alexandria, converted during a pilgrimage to Jerusalem through a mystical encounter before an icon of the Theotokos, she spent the following forty-seven years alone in the Jordanian desert in total repentance. Her story says to those who feel too far from God to return: no one is too far. Repentance is always possible. In American Orthodox parishes, the Sunday of Mary of Egypt often draws some of the largest weekday Matins attendance of the Lenten season — her story resonates powerfully in a culture familiar with the language of addiction, recovery and radical transformation.
The Akathist Saturday
The fifth Saturday of Great Lent is Akathist Saturday — the only bright feast of joy in the heart of Lent. The Akathist Hymn to the Theotokos, the most celebrated Marian hymn in the Byzantine tradition, is sung in its entirety through the night. This ancient hymn — beginning with "Rejoice, O unwedded Bride" — celebrates the Mother of God as the one who bore the Savior of the world in her womb. Rejoice — the opening word of the Akathist — rings out like an oasis of light in the middle of the Lenten desert.
The Great Canon of Saint Andrew of Crete
The Great Penitential Canon of Saint Andrew of Crete is one of the most extraordinary liturgical texts in the entire Christian tradition. Composed in the 7th century by Andrew, Bishop of Crete, it consists of 250 troparia — the longest liturgical canon ever composed. It is sung at two points during Great Lent:
- First week of Lent: sung in four parts, on the evenings of Monday through Thursday (the four "Great Compline" services)
- 5th week of Lent: sung in its entirety at a single night service (the Standing of Mary of Egypt), on Thursday evening
The Great Canon is a poetic meditation on the entirety of Holy Scripture — Old and New Testament — viewed through the lens of personal repentance. Andrew traverses the whole Bible, from Creation to the Apocalypse, identifying himself with every sinful figure: "I have sinned as Adam sinned, I have sinned as Cain sinned, I have sinned as David sinned..." And he also identifies with every figure of conversion and repentance. This double movement — acknowledgment of sin and confidence in mercy — is the heart of Orthodox Lenten spirituality.
For many Orthodox Christians, the first week of Great Lent with the Great Canon is the most intense and most beautiful liturgical experience of the entire year — total immersion in the Word of God and in repentance, carried by melodies of heartbreaking beauty. For converts to Orthodoxy in America, encountering the Great Canon for the first time is often described as one of the experiences that confirmed their decision to enter the Church.
The Liturgy of the Presanctified Gifts: the liturgical heart of Lent
During Great Lent, the ordinary Divine Liturgy — of Saint John Chrysostom or Saint Basil — is suspended on weekdays. In its place, on Wednesday and Friday evenings (and sometimes Monday), the Church celebrates the Liturgy of the Presanctified Gifts, attributed to Saint Gregory the Dialogist (Saint Gregory the Great), and of considerable antiquity.
This liturgy is not a new eucharistic consecration — it is the distribution of the Gifts (the Body and Blood of Christ) that were consecrated at the previous Sunday's Liturgy and reserved on the altar. It is celebrated in the evening, after a day of fasting — which means the faithful receive Communion at night, having fasted all day. This connection between bodily fasting and eucharistic Communion is one of the strongest expressions of the theology of Great Lent.
One of the most striking moments of this liturgy is the great procession with the Presanctified Gifts, during which all the faithful kneel and prostrate themselves singing: "Now the powers of heaven serve with us invisibly." For many Orthodox Christians in America — especially those who work full-time and can only attend one weekday service — the Wednesday or Friday Presanctified Liturgy becomes the spiritual anchor of their entire Lenten week.
Holy Week: the culmination of Great Lent
Holy Week (Strastnaya Sedmitsa in Church Slavonic, Megali Evdomada in Greek) is technically distinct from Great Lent proper — it begins after Palm Sunday. But it is Lent's direct and inseparable fulfillment. Each day of Holy Week is a deeper immersion into the mystery of Christ's Passion.
Holy Monday, Tuesday and Wednesday
The first three days of Holy Week are devoted to the great Gospel readings about Christ's final days in Jerusalem. The characteristic service of these three days is the Bridegroom service (Nymphios) — celebrated late in the evening, in deep semi-darkness, with the reading of the parable of the ten virgins and the chant: "I see Your bridal chamber adorned, O my Savior, and I have no wedding garment to enter therein." On Wednesday evening, a Liturgy of the Presanctified Gifts is celebrated for the last time.
Holy Thursday: the Last Supper and the Twelve Passion Gospels
Holy Thursday is one of the liturgically richest days of the entire year. In the morning, the Divine Liturgy of Saint Basil with Vespers commemorates the institution of the Eucharist at the Last Supper. In the evening, one of the longest and most solemn services of the year: the reading of the Twelve Passion Gospels (Dodekaevangéliou), lasting two to three hours. Each Gospel is separated by antiphons and hymns. The faithful stand throughout, holding lit candles. In American parishes, this service draws some of the year's largest attendance — including many non-Orthodox friends and family members of parishioners, drawn by word of its extraordinary beauty.
Holy Friday: the Crucifixion and the Epitaphios
Holy Friday is the day of absolute fasting — the strictest of the year. The morning service (Royal Hours) proclaims the Passion narratives. In the afternoon, at the hour of Christ's death (3 PM), the Great Vespers commemorates the taking down from the Cross. And in the evening, the Epitaphios — the embroidered burial shroud of Christ — is carried solemnly around the church or through the streets, led by the clergy and followed by the faithful with candles and flowers. In the United States, Holy Friday falls on an ordinary workday in most years — it is not a federal holiday. But many Orthodox Christians take the day off, and in cities with significant Orthodox populations — New York, Chicago, Los Angeles, Boston — the outdoor Epitaphios procession can stop traffic and draw curious onlookers from the surrounding neighborhood, becoming a small but vivid public witness to the faith.
Holy Saturday: the silence of the tomb
Holy Saturday is the quietest and most mysterious of all days. Christ lies in the tomb. The morning liturgy sings the Lamentations before the Epitaphios — a poetic meditation on the death of Christ, among the most beautiful texts in the Byzantine tradition. Then everything is suspended in waiting. In the afternoon, the Divine Liturgy of Saint Basil is celebrated with Vespers — the transition begins: the Old Testament readings recapitulate the entire history of salvation, and at the moment of the Epistle reading, the liturgical vestments shift from black to the white of the Resurrection.
The fasting rules of Great Lent in detail
The fasting rules of Great Lent according to the strict monastic Typikon are among the most demanding in all of Christianity. They are best understood by keeping in mind that they were designed for monastic life — and that their application to laypeople is always to be adapted according to each person's capacities and the guidance of a spiritual father or confessor.
| Day of the week | Fasting rule |
|---|---|
| Monday, Wednesday, Friday | Strict fast: vegetables, legumes, grains, bread, water. No oil, no wine, no fish |
| Tuesday, Thursday | Cooked vegetables with oil and wine permitted. No fish |
| Saturday, Sunday | Oil, wine, cooked vegetables permitted. No fish (except on feast days) |
| March 25 (Annunciation) | Fish permitted regardless of the day of the week |
| Palm Sunday | Fish permitted |
| Holy Thursday | Oil and wine permitted once, in the evening after the Liturgy |
| Holy Friday | Absolute fast — nothing until evening (or until the Paschal night) |
| Holy Saturday | Strict fast until the Paschal night |
Forbidden throughout the entire Great Lent: meat, poultry, fish (except on the two days noted), dairy products (cheese, butter, milk, cream), eggs.
Always permitted: fresh and cooked vegetables, legumes (lentils, chickpeas, beans), grains, bread, egg-free pasta, rice, fresh and dried fruit, nuts, mushrooms, olives, shellfish and other seafood without a backbone (mussels, shrimp, squid, octopus, crab — according to tradition), water, herbal tea, coffee.
A note on shellfish: According to the Byzantine Typikon, invertebrate seafood without red blood is generally permitted even on strict fast days. This rule is more broadly applied in Greek and Antiochian practice. In the Slavic tradition (Russian, Serbian, Romanian), the interpretation is sometimes stricter.
Important pastoral note: In Orthodox parishes throughout the English-speaking world, priests consistently emphasize adapted fasting over abandoned fasting. A partial fast observed with perseverance is worth far more than a strict fast abandoned after three days. The goal is not dietary perfection but spiritual transformation — and a rule that is sustainable is a rule that forms the soul.
How to begin Great Lent: practical guidance
Beginning Great Lent for the first time — or returning to it after a long absence — can feel overwhelming. Here is practical guidance drawn from the experience of Orthodox parishes in the English-speaking world.
Start where you are, not where you think you should be
The most common mistake of Lenten beginners is attempting the full monastic Typikon from day one. This almost always fails — and the failure produces discouragement that can last for years. Far better to choose a realistic commitment and keep it: eliminate meat and dairy, add an evening prayer rule, attend the Great Canon services if at all possible. The following year, go further. Lenten discipline, like physical training, builds incrementally — and the soul that perseveres through a modest Lent for ten years is further along than the soul that collapses under an ambitious Lent after one week.
Find a confessor
Great Lent is inseparable from confession. The Orthodox tradition recommends confessing at least once during Lent — ideally more. Confession is not an administrative formality: it is the moment when the interior work of Lent takes concrete form and receives a blessing. In most Orthodox parishes in the US and UK, priests make themselves particularly available for confession during Great Lent — many offer extended confession hours on weekday evenings before or after the Presanctified Liturgy.
Attend at least some services
Great Lent is not lived only at the table — it is lived in the church. Even for those who cannot attend weekday services, the five Sunday Liturgies of Great Lent each have their own richness. And if only one thing is to be done beyond Sunday attendance, it is to attend at least one performance of the Great Canon of Saint Andrew of Crete — an unparalleled spiritual and musical experience that many Orthodox Christians describe as the most beautiful service of the entire year.
Great Lent in the English-speaking world: finding a parish
Orthodox parishes throughout the United States, Canada, the United Kingdom and Australia celebrate Great Lent with the full range of services. The Greek Orthodox Archdiocese of America has parishes in every major American city — most celebrate the Great Canon and the Presanctified Liturgy on a full schedule. The Antiochian Orthodox Christian Archdiocese — with its large convert population — is often particularly welcoming to inquirers and often publishes Lenten schedules and explanatory materials in accessible English. The Orthodox Church in America (OCA), the Serbian Orthodox Diocese and Russian, Romanian and Ukrainian parishes round out a richly varied landscape. In the UK, the Greek Orthodox Archdiocese of Thyateira and Great Britain and various OCA and Antiochian missions observe Great Lent fully. Many parishes in all jurisdictions are genuinely welcoming to non-Orthodox visitors — contact your nearest parish and ask: you will almost certainly be invited.
FAQ — Frequently asked questions about Orthodox Great Lent
How long is Orthodox Great Lent?
Great Lent proper lasts 40 days, from Clean Monday to Lazarus Saturday. It is followed by Holy Week (7 additional days, from Palm Sunday to Holy Saturday). The total duration including Holy Week is therefore 48 days — but Great Lent and Holy Week are two distinct liturgical periods. The 40-day length mirrors Christ's forty days of fasting in the desert, as well as Moses' forty days on Sinai and Elijah's forty-day journey to Horeb.
When does Orthodox Great Lent begin each year?
Great Lent always begins on Clean Monday, seven weeks before Orthodox Pascha. Because Orthodox Pascha is a movable feast calculated according to the Julian calendar, the date of Clean Monday shifts from year to year — it can fall anywhere between mid-February and mid-March. The dates for the coming years are listed in the table above.
Can you eat fish during Orthodox Great Lent?
Fish is permitted on only two days during Great Lent: the Annunciation of the Mother of God (March 25) and Palm Sunday. These two feasts are significant enough to lighten even the strictest fast of the year. On all other days of Great Lent, fish is not permitted — though shellfish and other invertebrate seafood are generally allowed according to the Byzantine Typikon.
What is the difference between Orthodox Great Lent and Catholic Lent?
The difference is considerable — and often surprises Americans who assume they are basically the same. Catholic Lent lasts 40 days and prescribes fasting on Ash Wednesday and Good Friday, and abstinence from meat on Fridays. Orthodox Great Lent is far longer (40 days plus Holy Week), dramatically stricter (no meat, no fish except two days, no dairy, no eggs), and accompanied by a liturgical life of incomparable density — daily services, the Great Canon, the Liturgy of the Presanctified Gifts. It transforms the entire life of the community, not just eating habits. Many American converts from Catholic backgrounds describe Orthodox Great Lent as what they always sensed Lent was supposed to be.
How do I fast during Great Lent as a beginner?
The best approach is gradual: begin by eliminating meat and dairy during the Lenten weeks, add abstinence from fish on Wednesdays and Fridays, and intensify the fast during Holy Week and on Holy Friday. The most important step is to speak with your priest, who can give you a fasting rule suited to your personal situation — health, work schedule, family obligations. Orthodox fasting is not a competition; it is a tool for transformation.
Do children have to fast during Great Lent?
Children are not subject to the same rules as adults. The Orthodox tradition encourages gradually initiating children into fasting according to their age and health — eliminating meat on Fridays for younger children, for example. The goal is for Lent to be a family experience, not an imposed burden. Pregnant and nursing women, the sick and the elderly are also dispensed from the strictest rules. In American Orthodox families, Great Lent often becomes one of the most cherished family rhythms — cooking new foods, attending services together, talking about the spiritual themes of each Sunday.
I'm not Orthodox — can I observe Orthodox Great Lent?
Many non-Orthodox Christians — especially those with Orthodox spouses, or those seriously inquiring about Orthodoxy — observe at least part of the Orthodox Lenten fast. There is no prohibition on this, and many priests welcome it warmly. The most natural entry point is the food fast (eliminating meat and dairy) and attending some of the services, particularly the Great Canon and the Presanctified Liturgy. If you are seriously considering Orthodoxy, Great Lent is one of the most formative times to be present in an Orthodox community — the depth of the tradition reveals itself more fully in these forty days than at almost any other time.
