When we first became Orthodox Christians, we found fasting to be a bit overwhelming. It was hard to find a simple, straightforward guide—most of what we came across was either too complicated, too long, or just confusing for someone new to the faith. That’s why we created this Orthodox fasting rules guide, combining the essential information we’ve gathered from various sources into something clear and easy to follow.
Whether you’re exploring Greek Orthodox fasting rules, Russian Orthodox fasting rules, or other Orthodox Christian fasting rules, this guide will help simplify the process so you can focus on the spiritual benefits of fasting.
1. Why Do Orthodox Christians Fast?
Orthodox fasting isn’t new; it dates back to the early Christians and the teachings of the Church Fathers. It’s rooted in Scripture, including examples of fasting from the Old Testament, such as Moses fasting before receiving the Ten Commandments. Christ Himself fasted for 40 days in the desert, setting an example for us to follow.
Fasting serves several purposes:
- Spiritual Growth: Fasting strengthens our prayer life and helps us open our hearts to the Holy Spirit.
- Repentance: It’s a time to reflect on our sins and seek forgiveness.
- Preparation: It readies us for the great feasts, such as Pascha (Easter), Nativity (Christmas), the Feast of the Transfiguration, etc.
By practicing fasting, we imitate the ascetic fasting of the saints and align ourselves with the traditions of the Orthodox Church.
2. What are the fasting dates for Orthodox?
Orthodox Christians follow a calendar filled with fasting and feast days. Here’s an overview of the canonical fasting periods and fast-free weeks observed throughout the year.
Weekly Fasts
Weekly Fasts:
Wednesdays and Fridays: These days honor Christ’s betrayal (Wednesday) and Crucifixion (Friday). On these days, we abstain from eating meat, dairy, and other animal products.
Communion Fast: Before receiving Holy Communion, we observe a total fast from food and drink, starting the evening before (usually Saturday night) until the Divine Liturgy.
Fasting Seasons
Fasting Seasons:
The fasting rules during the main fasting seasons are mostly consistent throughout the year, but small variations can make a big difference. For example, during the Nativity Fast, parishioners are often allowed to have fish, wine, and oil on many weekdays, while these are not permitted during Great Lent. Additionally, the way we prepare for these seasons isn’t the same. Longer fasting periods like Great Lent require more spiritual and practical planning compared to shorter ones like the Dormition Fast. That’s why it’s so important to familiarize ourselves with these main fasting seasons and plan ahead to follow the rules with care and intention.
Main Fasting Seasons
Main Fasting Seasons:
Great Lent: The most well-known fasting season, Orthodox Lent fasting rules begin on Clean Monday and last for six weeks, followed by Holy Week. During this time, we focus on repentance and spiritual renewal. The first week of Lent includes special services like the Sunday of the Publican and the reading of the Canon of St. Andrew.
Nativity Fast: From November 15 to December 24, we prepare for the Nativity of Christ. The rules are similar to those for Lent but slightly less strict toward the end.
Dormition Fast: This 15-day fast in August honors the Virgin Mary, leading to the Feast of her Dormition (Assumption).
Fast of the Holy Apostles: This fast begins the second Monday after Pentecost and ends on June 29, the Feast of Saints Peter and Paul.
Other Fasting Days
Other Fasting Days:
Eve of Theophany: A strict fast on January 5.
Beheading of St. John (August 29): A day of strict fasting in memory of his martyrdom.

Fasting seasons give us a rhythm of spiritual growth throughout the year. While the rules are mostly the same, understanding the unique aspects of each season—like the allowances during the Nativity Fast or the extra preparation needed for Great Lent—helps us stay focused and prepared. By planning ahead and embracing these seasons thoughtfully, we can deepen our faith and make the most of these opportunities to draw closer to God.
Fast-Free Weeks and Feast Days
Fast-Free Weeks and Feast Days:
In the Orthodox Church, fasting and feasting go hand in hand, creating a rhythm that balances discipline with celebration. Just as fasting draws us closer to God through self-restraint and prayer, feasting allows us to joyfully celebrate His blessings. The Church sets aside specific fast-free weeks and Feast Days to focus on the joy of major events in our faith.
Fast-Free Weeks
Fast-Free Weeks
The Orthodox calendar includes fast-free weeks, giving us a break from fasting so we can fully embrace God’s grace and the joy of His work:
- Bright Week (the week after Pascha): Celebrates Christ’s Resurrection, the victory over death, with feasting and thanksgiving.
- The week after Pentecost: Honors the Holy Spirit’s descent and the birth of the Church, a time of spiritual renewal and gratitude.
- The week after the Nativity of Christ: Rejoices in the birth of our Savior, highlighting God’s love and redemption.
These weeks follow seasons of intense fasting, like Great Lent or the Nativity Fast, reminding us that moments of joy and rest are essential to our spiritual journey.
Main Feast Days
Main Feast Days
Feast days throughout the year celebrate key moments in Christ’s life, the Theotokos, and the saints. Some of these feasts occur during fasting seasons, and the Church allows for exceptions to fasting rules as a way to honor their significance:
- Palm Sunday: During Great Lent, this feast permits fish, wine, and oil to celebrate Christ’s triumphal entry into Jerusalem.
- Feast of the Transfiguration: Observed during the Dormition Fast, this feast allows for fish, wine, and oil, reflecting the divine glory revealed on Mount Tabor.
Feast days remind us to honor God’s blessings with joy and thanksgiving, even during times of fasting, creating a balance between self-discipline and celebration.
Fast-free weeks and Feast Days are gifts from the Church that remind us of the joy and gratitude we are called to experience as Orthodox Christians. By embracing both fasting and feasting, we grow closer to God, balancing seasons of spiritual discipline with moments of joyful celebration. Through this rhythm, we live out the fullness of our faith and experience God’s abundant grace.
3. What do Orthodox eat on fasting days?
During fasting periods, the diet focuses on simple plant-based foods:
- Shellfish: Shrimp, crab, lobster, oysters, etc.
- Vegetables: Potatoes, broccoli, carrots, spinach, zucchini, and more.
- Fruits: Apples, bananas, citrus, and berries.
- Grains: Whole grains like brown rice, oats, and quinoa.
- Legumes: Lentils, chickpeas, and beans.
- Nuts and Seeds: Almonds, walnuts, sunflower seeds, and peanut butter.
- Vegetable Oils: Olive oil and other plant-based oils are permitted on non-strict fasting days, such as Saturdays and Sundays during Great Lent.
4. What can't you eat during orthodox fasting?
The following foods are avoided during fasting periods:
- Meat Products: Beef, chicken, pork, and all other meats.
- Dairy Products: Milk, cheese, yogurt, butter, and cream.
- Eggs: All types of eggs, including chicken and duck eggs.
- Fish: Fish with backbones is generally avoided, but it is permitted during specific feast days or fasting seasons such as the Nativity fast, the fast of the Apostles, etc.
5. Are Fish Allowed During Orthodox Fast?
Short answer: Yes—but only on certain feast days and in a few lighter fasting seasons.
Use the lists below to see when you may add fish to the table:
Feasts that always permit fish:
- Annunciation (March 25)
- Palm Sunday (Sunday before Pascha)
- Transfiguration (August 6)
These three feasts override even the strictest fasts, so feel free to serve fish in celebration.
Fasting seasons that include fish days:
| Season | Typical Fish Rule | Key Details |
|---|---|---|
| Nativity Fast (Nov 15 – Dec 24) | Fish allowed most days | Skip fish on Wednesdays, Fridays, and the final five days (Dec 20-24). |
| Apostles’ Fast (variable; ends June 28) | Fish allowed on many days | Customarily permitted whenever wine and oil are allowed, but the last week often tightens. |
If health, pregnancy, or age makes a fish-free diet hard, talk with your priest; the fast should heal, not harm. Enjoy fish on the appointed days, and let the taste remind you of the joy tucked inside every fast.
6. Is alcohol OK during fasting?
Alcoholic drinks are usually limited during fasting periods. Hard liquor is avoided entirely, while moderate consumption of wine or beer may be allowed on weekends or major feast days, depending on your local tradition.
For example:
- Allowed Days: Saturdays and Sundays (except during Holy Week), the Feast of the Annunciation (March 25), and other significant feast days.
- Strict Prohibition: Holy Week, especially Holy Thursday, Holy Friday, and Holy Saturday.
As always, consult your spiritual father for specific guidance.
7. What can you not do when fasting?
Each soul walks a unique road to salvation. Your battle may differ from mine. The Church gives general rules and marks strict fast days, but every heart has its own passions.
Here is a list to be use as a starting compass on fasting days, not a final map:
- Gluttony – Do not stuff yourself. On strict fast days limit the number of meals and the amount of food. Skip meat, dairy, and eggs. Even on fish days—Palm Sunday fish and other allowances—eat lightly and stay grateful.
- Greed – Do not hoard. Share what you save with the poor. Generosity keeps the fast pure and loosens greed’s grip.
- Lust – Guard your eyes. Avoid shows that stir desire, especially on Wednesday evening after a Presanctified Liturgy. Choose Scripture or the lives of saints like the Synaxis of the Archangel Gabriel instead.
- Wrath – Hold your tongue. Speak gently, even when hunger bites. Fasting aims to drive out every evil spirit, not feed anger.
- Envy – Rejoice in another’s blessing. Give thanks during a friend’s patronal feast day of a parish or a feast of a great saint. Envy poisons community life.
- Pride – Skip the boasting. Do not brag about how many weeks of Lent you keep or the kinds of foods you refuse. Quiet humility grows best under obedience.
- Sloth – Stay awake in prayer. Attend Presanctified Liturgies during the weekdays of Great Lent and other fasting seasons of the Church. When work or small children limit you, pray at home and keep watch over your heart.
Walk this path with patience, and Christ will meet you step by step.
8. Orthodox Fasting Rules For Lent
Great Lent is the most spiritually significant fasting season in the Orthodox Church, lasting six weeks, followed by Holy Week. It’s a time of repentance, prayer, and spiritual renewal, with unique traditions and strict rules of fasting to guide us through this sacred journey.
Meatfare and Cheesefare Weeks
Meatfare and Cheesefare Weeks
The two weeks before Lent help us gradually prepare for the full fasting season:
- Meatfare Week: This is the last week to eat meat before Lent. It ends with Meatfare Sunday (the Sunday of the Last Judgment), which reminds us to prepare for repentance.
- Cheesefare Week: The following week, we stop eating meat but continue enjoying dairy products. It concludes with Cheesefare Sunday (or Forgiveness Sunday), when we ask forgiveness from one another and prepare to begin Lent.
These transitional weeks ease us into the stricter fasting of Lent, helping us adjust both spiritually and physically.
Holy Week
Holy Week
The final week of Great Lent, Holy Week, is the most solemn period of the Church year. Each day recalls Christ’s Passion and is marked by special fasting and services:
- Palm Sunday: Celebration but still fasting—fish, wine, and olive oil are the only extras; no meat, dairy, or eggs.
- Holy Monday: Strict fast resumes. Eat two light vegan meals without oil if you must.
- Holy Tuesday: Same strict pattern as Monday. Keep portions small and spirits watchful.
- Holy Wednesday: Another strict-fast day. Many receive Holy Unction in the evening; eat lightly so you can commune.
- Holy Thursday: The rule relaxes a little. Wine and olive oil return, but fish stays off the table.
- Holy Friday: Fast at its peak. Tradition urges total abstinence until sunset; water or bread only if health requires.
- Holy Saturday: Still a fast day, though wine and oil are blessed after the morning Vesperal Liturgy. Most wait until the Paschal vigil to break the fast with joy.
These services help us enter deeply into the mystery of Christ’s sacrifice and victory. Remember, local customs vary, so follow your parish chart and ask your priest when in doubt.
Bright Week (Fast-Free Period After Pascha)
Bright Week (Fast-Free Period After Pascha)
Following the intensity of Lent and Holy Week, Bright Week begins on Easter Sunday and is a fast-free period filled with joy and celebration. During this time, we fully embrace the freedom and hope brought by Christ’s Resurrection, setting aside all fasting rules as we rejoice in His victory over death.
Great Lent is unique because it combines spiritual preparation, strict fasting, and meaningful traditions to lead us closer to Christ. From the gradual transition of Meatfare and Cheesefare Weeks to the solemnity of Holy Week, this season invites us to focus on repentance and renewal, preparing our hearts for the joy of Pascha and the hope of eternal life.
9. Exceptions to the Fasting Rules
While the Orthodox fasting rules encourage strict observance, the Church allows flexibility in certain situations:
- Health Needs: Those with medical conditions or poor health are not expected to follow the rules strictly.
- Pregnancy and Children: Expectant mothers and young children are typically exempt.
- Travel or Isolation: In cases like the situation of an isolated Orthodox believer, the Church provides guidance to adapt the rules.
- Elderly or Physically Demanding Jobs: Adjustments are made to ensure safety and well-being.
In all cases, it’s best to consult your priest or spiritual father for personalized guidance.

Final Thoughts: How to fast correctly?
Fasting is a tool for spiritual growth, not just a dietary change. It helps us:
- Focus on prayer and repentance.
- Prepare for the Kingdom of God.
- Strengthen our relationship with the Holy Spirit.
Remember, fasting isn’t about perfection but progress. Start small, follow the broad rules, and trust in God’s grace to guide you. Whether you’re observing Lent fasting rules Orthodox traditions or preparing for a major feast day, fasting is a gift that enriches both body and soul.
Frequently Asked Questions
No. Strict fast days—every Wednesday and Friday, the six weeks of Great Lent, the Beheading of St. John, and the Holy Forty Martyrs of Sebaste—ban eggs, dairy, and meat. Even fish-days like Palm Sunday or the Forefeast of the Annunciation still forbid eggs. Ask your priest if health needs arise.
Yes. Coffee is not an alcoholic drink, and the letter of the rule speaks mainly about food. Keep it black and modest; limit cups so caffeine never rules you. The Apostles’ Fast and other lighter seasons follow the same guidance.
Usually, yes. Honey is not animal flesh or dairy. Different traditions cap sweets during the sixth week, so follow parish custom. Use honey sparingly as part of your spiritual disciplines.
You can. Small children, pregnant mothers, and the ill may need supplements even on strict fast days. Choose plant-based capsules when possible, and swallow with a little allowed food if nausea strikes. Always seek guidance from your spiritual father and doctor.
Fasting seasons aim to quiet the heart and drive out every evil spirit. After supper—especially on Wednesday evening following Presanctified Liturgies—many families turn screens off. Swap idle shows for Scripture, saints’ stories such as the Synaxis of the Archangel Gabriel, or silent prayer. Let each day of fasting pull you closer to Christ.

Are shellfish allowed during regular fast days throughout the year? If so, how about during lent?
Thierry
Hi Tamar!
Thank you for reaching out. Yes, shellfish are generally allowed on regular fast days throughout the year for parishioners following a standard fasting plan—this applies to Lent as well, since shellfish isn’t classified as meat.
However, for those on an ascetic fasting plan, limited shellfish intake may be encouraged or even omitted entirely during stricter periods.
If you’d like to explore the differences between these fasting plans, check out this post:

Are cookies and cake (sweets) OK? ie...cookies (vegan)
Thierry
Hi Cate,
Great question! In many Orthodox traditions, as long as sweets (like cookies) are vegan—meaning no dairy or eggs—they’re generally considered acceptable during fasting periods. Of course, some people choose to be extra strict or might have guidance from a spiritual father that suggests otherwise, especially when it comes to sweets. But if you’re using plant-based ingredients, you should be good to go! Moderation is always key. Thanks for stopping by, and feel free to reach out if you have any more questions!
Best, Thierry
