The Fixed and the Movable Year
The Orthodox year is not one cycle but two, running simultaneously and keyed to two different kinds of reckoning: a fixed cycle of dated feasts in the Menaion, and a movable cycle computed from Pascha in the Triodion and Pentecostarion. Understanding that these are genuinely independent systems — and that the Typikon exists largely to combine them — is the prerequisite for everything this collection says about the calendar.
Tradition: Pan-Orthodox
Two Cycles, Two Reckonings
The fixed cycle assigns commemorations to calendar dates that recur every year: the Nativity of Christ on 25 December, Theophany on 6 January, the Meeting of the Lord on 2 February, the Annunciation on 25 March, the Transfiguration on 6 August, the Dormition on 15 August, the Nativity of the Theotokos on 8 September, the Exaltation of the Cross on 14 September. Every day of the year has its saints. The propers are printed in the twelve-volume Menaion, one book per month — hence the name, from mēn, “month” (see Orthodoxy: The Church Calendar; The Octoechos, Triodion, Menaion, and the Typikon).
The movable cycle assigns commemorations by their distance from Pascha, and therefore shifts by weeks from year to year: the Sunday of the Publican and Pharisee, Meatfare and Cheesefare, Clean Monday, the Sundays of Great Lent, Lazarus Saturday, Palm Sunday, Holy Week, Pascha, the Sundays of the Pentecostarion, the Ascension on the fortieth day, Pentecost on the fiftieth, All Saints on the Sunday following. Its propers are in the Triodion (from the Publican and Pharisee to Great Saturday) and the Pentecostarion (from Pascha to All Saints Sunday) — together a continuous span of some eighteen or nineteen weeks, centred on Pascha and dependent on it (see Orthodoxy: Great Lent; Pascha, the Feast of Feasts).
The decisive point — and it is the one most often missed — is that these two cycles are not merely two lists. They are keyed to two different reckonings.
The fixed cycle is read off a solar date grid: whatever calendar the local church uses to number the days of the year. The movable cycle is computed by the Paschalion, a self-contained lunisolar arithmetic that takes a year, applies a nineteen-year lunar cycle and a defined ecclesiastical equinox, and returns a date for Pascha; everything else in the movable cycle is then counted forwards or backwards from that date (see How Pascha Is Reckoned).
Because they are separate systems, they can in principle be separated in practice. That is not a hypothetical. It is precisely what happened in the twentieth century, and it is why this collection needs section 04 before it can have section 05.
The Year Begins in September
The liturgical year opens on 1 September, the Indiction, a starting-point taken over from the Byzantine fiscal cycle of fifteen years and long since fixed for the Church by usage (The Oxford Dictionary of Byzantium, ed. Kazhdan, Oxford: Oxford University Press, 1991, s.v. “Indiction”; The Festal Menaion, trans. Mother Mary and Kallistos Ware, London: Faber and Faber, 1969, Introduction). September 1 is kept liturgically but is not a Great Feast; its hymns take up Christ’s reading in the synagogue at Nazareth, “The Spirit of the Lord is upon me” (Luke 4:16–21).
The consequence is a year framed by the Mother of God: the first Great Feast to fall within it is her Nativity on 8 September, and the last is her Dormition on 15 August. The year of the Lord’s feasts is set inside the span of his Mother’s life on earth — a point of real theological weight, developed at The Twelve Great Feasts and the Calendar.
The Typikon’s Real Work
If the two cycles ran side by side without touching, no one would need a Typikon. They touch constantly, and the book exists to say what happens when they do.
The relevant chapters are the Markan chapters (Markovy glavy, “chapters of Mark”), traditionally ascribed to a monk Mark of the Lavra of St Sabbas, which prescribe how a fixed feast is served when it falls on a Sunday, in a week of the Triodion, in Holy Week, in Bright Week, or in the afterfeast of another feast (see Orthodoxy: The Church Calendar; Skaballanovich, Tolkovyi Tipikon [The Explanatory Typikon], 3 vols., Kiev, 1910–1915). The Russian Typikon devotes a great deal of space to them.
Some of the concurrences the Typikon handles:
- The Annunciation (25 March) is movable in nothing but falls anywhere from the fourth week of Lent to Bright Week. Its collision with Holy Week and with Pascha itself has its own elaborate rubrics; the coincidence with Pascha is Kyriopascha, the “Lord’s Pascha,” in which the conception of Christ and his rising are sung on one day.
- The Meeting of the Lord (2 February), forty days after the Nativity, can fall inside the preparatory weeks of the Triodion when Pascha is early, and its afterfeast must then be curtailed.
- The Exaltation of the Cross (14 September) is a Great Feast that is also a strict fast day — a fixed feast whose character overrides the ordinary festal relaxation (see Orthodoxy: Fasting Periods; The Exaltation of the Cross).
- Great Feasts falling on Wednesday or Friday relax the weekly fast in a graded way that the Typikon specifies feast by feast.
- Saints’ commemorations in Great Lent are, by the ancient rule, not celebrated with a full festal office on weekdays; the Council of Laodicea directs that the memorials of martyrs falling in Lent be kept on Saturdays and Sundays (Laodicea, canon 51; in The Rudder [Pedalion], trans. Cummings, Chicago, 1957). This is the fixed cycle yielding to the movable.
The general principle visible in these rubrics is that the movable cycle has priority. Pascha governs, and the fixed calendar accommodates itself. That priority is itself a theological statement: the Resurrection is not one feast among the year’s feasts but the centre from which the year is measured.
The Fasts Straddle Both Cycles
The clearest place where the two reckonings are welded together is the fasting year, and it is worth setting the four fasts out by how they are anchored, because this is exactly the structure that later sections will find under strain:
| Fast | Start | End | Anchoring |
|---|---|---|---|
| Great Lent and Holy Week | Clean Monday | Great Saturday | Wholly movable |
| Apostles’ Fast | Monday after All Saints Sunday (movable) | 28 June, eve of Ss Peter and Paul (fixed) | Movable start, fixed end |
| Dormition Fast | 1 August | 14 August | Wholly fixed |
| Nativity Fast | 15 November | 24 December | Wholly fixed |
Three of the four are anchored at both ends within a single reckoning. The Apostles’ Fast is not. Its beginning is counted from Pascha and its end is a date in the Menaion. It is therefore the one structure in the entire liturgical year whose length is determined by the relation between the two cycles — which means it is the one structure that registers, immediately and arithmetically, any change in that relation (see Orthodoxy: Fasting Periods, which gives its variable length as roughly eight days to six weeks).
That single line in the table is the hinge of this collection. It is not raised here to score a point; it is raised because a reader who has not seen the structural fact will not be able to follow the argument of The Case for the Old Calendar, or to weigh the reply at The Case on the Other Side.
What Follows
Two dated cycles, keyed to two reckonings, welded at several points and above all at the Apostles’ Fast. Section 03 takes up the movable reckoning — how Pascha is computed and what the First Ecumenical Council actually settled about it. Section 04 takes up the fixed one — what the Julian calendar is, how it drifts, and precisely which of these structures the drift touches.
