The Complete Orthodox Fasting Calendar 2025: 7 Essential Periods And Strict Rules Revealed

Contents

The Orthodox Fasting Calendar for 2025 is a spiritual roadmap for millions of Eastern Orthodox Christians, guiding them through a year of ascetic discipline that culminates in the celebration of Pascha. Unlike the Western calendar, the Orthodox dates for Easter and the associated Lenten cycle are calculated using the Julian Calendar and specific ecclesiastical rules, resulting in unique dates for all movable feasts.

As of today, the dates for all four major fasts and the fixed single-day fasts for 2025 are finalized, with the most significant date being the unified celebration of Orthodox Pascha on April 20, 2025, the same date as Western Easter. This article provides the complete, accurate, and up-to-date schedule for every major fast, helping you prepare your spiritual and dietary journey for the coming year.

The Four Major Fasting Seasons of the Orthodox Church in 2025

The four main multi-day fasts are the cornerstones of the Orthodox liturgical year. These periods are characterized by varying degrees of abstinence from meat, dairy products, and often fish, wine, and oil, depending on the season and the day of the week.

1. Great Lent (The Pre-Pascha Fast)

The Great Lent is the longest and most stringent fasting period, leading up to the Feast of Feasts, Holy Pascha (Easter). It is a 40-day journey of repentance, prayer, and almsgiving, starting on Clean Monday.

  • Start Date: Monday, March 3, 2025 (Clean Monday)
  • End Date: Saturday, April 19, 2025 (Holy Saturday)
  • Duration: 48 Days (including Holy Week)
  • Key Observances: Cheesefare Week (precedes the fast), Holy Week, Lenten Tridion.
  • Strictest Days: The first week and Holy Week are the most severe, with many observing a complete fast on Clean Monday and Great Friday.

2. The Apostles' Fast (Peter and Paul Fast)

The Apostles' Fast, also known as the Peter and Paul Fast, is a movable fast that begins the Monday after All Saints' Sunday (the second Sunday after Pentecost) and concludes on the Feast of the Holy Apostles Peter and Paul. Its length varies each year depending on the date of Pascha.

  • Start Date: Monday, June 16, 2025
  • End Date: Friday, July 11, 2025 (Feast of Sts. Peter and Paul is July 12)
  • Duration: 26 Days
  • Fasting Rule: Generally less strict than Great Lent, with fish often permitted on Tuesdays, Thursdays, Saturdays, and Sundays.

3. The Dormition Fast (Theotokos Fast)

The Dormition Fast is a relatively short but strict fast in honor of the Holy Theotokos (Mother of God), leading up to the Feast of the Dormition of the Theotokos. It is considered one of the four canonical fasting periods.

  • Start Date: Friday, August 1, 2025
  • End Date: Thursday, August 14, 2025
  • Duration: 14 Days
  • Key Feast Day: The Transfiguration of the Lord on August 6 is a major feast day during this fast, and fish, wine, and oil are permitted on this day, regardless of the day of the week.

4. The Nativity Fast (St. Philip's Fast / Christmas Fast)

The Nativity Fast, also called Philip's Fast because it begins the day after the Feast of St. Philip the Apostle, is a 40-day preparation period for the Nativity of Christ (Christmas). The rules become stricter in the final week.

  • Start Date: Friday, November 28, 2025
  • End Date: Tuesday, January 6, 2026 (The Nativity is Jan 7)
  • Duration: 40 Days
  • Fasting Rule: Fish is generally allowed on weekends and certain feast days until the final weeks of the fast. The fast is broken with the Christmas Eve meal, which is traditionally meatless, followed by the full feast on Christmas Day.

Fixed Single-Day Fasts and Weekly Disciplines

In addition to the four major fasts, the Orthodox Church observes several single-day fasts throughout the year, which are fixed on the calendar regardless of the day of the week. The general rule for these days is abstinence from meat, dairy, eggs, fish, wine, and oil, unless a major feast day falls on them.

The Three Fixed Single-Day Fasts for 2025

These three days are observed with strict fasting, often including abstinence from wine and oil, unless a major feast of the Lord or the Theotokos occurs on the same date.

  1. Epiphany Eve (Paramony): Sunday, January 5, 2025. This fast prepares the faithful for the Feast of Theophany (Epiphany) on January 6.
  2. The Beheading of St. John the Baptist: Friday, August 29, 2025. This day commemorates the martyrdom of the Forerunner.
  3. The Exaltation of the Holy Cross: Sunday, September 14, 2025. The fast is observed in remembrance of Christ’s suffering on the Cross. Since this date falls on a Sunday in 2025, the strictness may be mitigated to allow wine and oil, but the abstinence from meat, fish, and dairy remains the rule.

The Perpetual Weekly Fast

The two most common and perpetual fasting days for Orthodox Christians are Wednesday and Friday. Wednesday is observed in remembrance of the betrayal of Christ by Judas Iscariot, and Friday in memory of His Crucifixion.

  • Wednesday Fast: Abstinence from meat, dairy, and eggs.
  • Friday Fast: Abstinence from meat, dairy, and eggs.
  • Fast-Free Weeks: There are five periods during the year, known as "fast-free" or "non-fasting" weeks, where the Wednesday and Friday fasts are suspended. These include the week after Pascha (Bright Week) and the week after the Nativity.

Understanding the Orthodox Fasting Rules and Intentions

The core intention of Orthodox fasting is not merely a diet but a spiritual discipline, a path to asceticism, and a means of preparing the body and soul for great feasts. The rules are complex and often vary slightly between jurisdictions (Greek Orthodox, Russian Orthodox, OCA, etc.), but the fundamental restrictions remain consistent.

The general hierarchy of abstinence is as follows:

  • Meat and Dairy: Abstinence is required on all fasting days.
  • Fish: Allowed during less strict periods (e.g., most days of the Apostles' and Nativity Fasts), but strictly forbidden during Great Lent and the Dormition Fast, except on specific feast days (e.g., the Annunciation and Transfiguration).
  • Wine and Oil: Allowed on weekends (Saturdays and Sundays) during the major fasts, and on certain feast days. Abstinence from wine and oil is often referred to as Dry Eating (*Xerophagy*), which involves consuming only uncooked or simply cooked vegetables, fruits, and bread.

It is crucial to remember that these rules are guidelines for the physically capable. The Church emphasizes that the true fast is from sin, and all fasting should be undertaken with the blessing and guidance of a spiritual father or parish priest, especially for the sick, the elderly, or pregnant women. The spiritual benefits of humility and charity always supersede the dietary restrictions.
