Every year, roughly two billion people celebrate Easter without knowing that its date is computed by a lunar algorithm older than algebra. The calculation is called the computus — Latin for "computation" — and it was standardized at the Council of Nicaea in 325 CE, when bishops from across the Roman Empire agreed that the resurrection of Christ should be commemorated on the first Sunday after the first full moon on or after the spring equinox.
Read that sentence again. It is a celestial instruction set. It binds the most important date in the Christian liturgical calendar to three astronomical inputs: the Sun's crossing of the celestial equator (the equinox), the Moon's opposition to the Sun (the full moon), and the seven-day cycle of the week (Sunday). No other major Western holiday works this way. Christmas is fixed. Thanksgiving is a formula of weekdays. Only Easter still moves with the sky.
The Nicaean bishops did not invent this system. They inherited it from the Alexandrian computists of the third century, who had inherited it from Jewish Passover reckoning, which itself descends from Babylonian lunisolar calendars stretching back to the second millennium BCE. The chain of transmission is unbroken: the same celestial mechanics that Babylonian priests used to time agricultural festivals in 1800 BCE determined that Easter 2026 falls on April 5.
Easter is the oldest continuously operating lunisolar algorithm in Western civilization. Every year it executes the same instruction: find the equinox, find the full moon, find the Sunday. The cosmos computes; the church obeys.
Here is how the algorithm ran this year. The astronomical spring equinox fell on March 20, 2026, at 10:46 AM Eastern Time. The ecclesiastical equinox — fixed at March 21 since the sixth century — followed the next day. The first full moon after the equinox, the Paschal full moon, peaked on April 1 at 10:12 PM Eastern. The first Sunday after that full moon: April 5.
But the full moon is not the only lunation that matters. Two days before Easter, on April 2, the New Moon formed at 12° Aries — conjunct the Saturn-Neptune stellium that has dominated the sky since the epochal conjunction at 0° Aries on February 20. This is the first New Moon to seed the Saturn-Neptune cycle into the cardinal fire of Aries. In mundane astrology, a New Moon conjunct Saturn-Neptune at the World Point is a seed chart for everything that will unfold over the next 36 years of the Saturn-Neptune cycle.
Easter 2026 falls inside that seed. The resurrection lands not in any ordinary sky, but in the opening days of the most significant planetary cycle to begin in over a millennium.
The resurrection archetype did not begin at Calvary. It was ancient before Judea existed.
The Sumerians told the story of Inanna descending to the underworld and returning to the living — a myth dated to approximately 1900 BCE, inscribed on clay tablets that survive today. The Egyptians told it of Osiris, dismembered by Set and reassembled by Isis, who reigned as lord of the dead and guarantor of eternal life. The Phrygians told it of Attis, the shepherd god who died beneath a pine tree and was mourned for three days before his devotees celebrated his return. The Greeks told it of Adonis, gored by a boar and resurrected each spring when anemones bloomed red from his blood.
In each case, the dying-and-returning god is bound to the same celestial event: the vernal equinox. The sun crosses the celestial equator. Day overtakes night. The agricultural world awakens. The god dies in winter and returns in spring because the god is the spring — a narrative encoding of the astronomical fact that the ecliptic crosses the equator twice a year, and that the northern crossing marks the return of warmth, growth, and life.
Before Easter there was Passover. Before Passover there was the Akitu festival of Babylon. Before Akitu there were Neolithic people watching the sun cross the equator and telling stories about what comes back from the dead. The resurrection is not a doctrine. It is a celestial observation dressed in narrative.
The early Church fathers understood the overlap. They debated it openly. Origen of Alexandria (c. 185–253 CE) argued that Christian Easter must be distinguished from Jewish Passover precisely because the two shared a lunar reckoning. The Council of Nicaea settled the matter by anchoring Easter to the equinox — the same astronomical event that had anchored every resurrection myth in the ancient world. Christianity did not reject the celestial mechanics of its predecessors. It formalized them.
Because Easter is astronomically determined, its position in the calendar is not random. It falls within a 35-day window — March 22 to April 25 — and its placement relative to other celestial events creates resonances that mundane astrology can read. Some Easters are unremarkable. Others land in windows of extraordinary planetary tension. The events that follow are rarely subtle.
The Easter Rising. Irish republicans seized the General Post Office in Dublin on Easter Monday, April 24, 1916, proclaiming an independent Irish Republic. The timing was deliberate — the rebels chose Easter specifically for its resurrection symbolism. A nation dead under colonial rule would rise again. The Rising failed militarily. The British executed fifteen leaders. But the executions created martyrs, and within six years Ireland had its independence. The resurrection narrative, timed to the astronomical Easter, created a political reality that outlasted the empire that suppressed it.
The Battle of Okinawa. On Easter Sunday, April 1, 1945, the United States Navy's Fifth Fleet and over 180,000 troops launched the invasion of Okinawa — the last major battle of World War II. The operation was codenamed "Iceberg." Easter morning, the day of resurrection, opened the bloodiest campaign of the Pacific theater: 12,520 Americans killed, an estimated 110,000 Japanese military dead, and between 40,000 and 150,000 Okinawan civilians. The atomic bombings of Hiroshima and Nagasaki followed four months later. The old world died at Easter. What rose from it was the nuclear age.
The Saturn-Neptune seed. Easter 2026 falls three days after the New Moon at 12° Aries conjunct the Saturn-Neptune stellium. Saturn-Neptune conjunctions have historically marked the dissolution of existing structures and the crystallization of new ones: the end of Tsarist Russia (1917), the death of Stalin (1953), the fall of the Berlin Wall (1989). The 2026 conjunction at 0° Aries — the World Point, the first degree of the zodiac — is the most potent placement this cycle has occupied in recorded history. Easter lands inside it. The resurrection archetype activates at the precise moment the sky signals the death of the old order and the birth of something that does not yet have a name.
There is a symbol hiding in plain sight. The Paschal lamb — the sacrifice at the center of both Passover and Easter — is a young ram. Aries is the ram. The first sign of the zodiac. The point of origin.
When the Council of Nicaea fixed Easter to the equinox, the vernal point had already precessed out of Aries into Pisces. But the symbolic architecture remained: Easter is the feast of the lamb sacrificed so that others might live, celebrated in the season of Aries, the sign of initiation, war, and new beginnings. The dying god is always a ram — from the ram caught in the thicket on Mount Moriah (Genesis 22) to the Lamb of God who takes away the sins of the world (John 1:29) to the Ram of Mendes in Egyptian theology.
In 2026, the symbolism collapses into literalism. Saturn and Neptune conjoin at 0° Aries — the first degree of the Ram. The New Moon seeds at 12° Aries. Easter falls three days later. The Paschal lamb is sacrificed, symbolically, at the exact zodiacal position where the ram begins. This is not an annual occurrence. The Saturn-Neptune conjunction at 0° Aries has not happened in over a thousand years. Whatever Easter 2026 initiates, it initiates at the deepest structural level the sky can offer.
The resurrection myth has always been astronomical. A god dies at the equinox and rises with the full moon. In 2026, that full moon falls in a sky shaped by the rarest conjunction in a millennium. The algorithm executes. What rises is not yet clear. But the seed chart says: this one counts.
The computus is a machine for determining a date. It knows nothing of meaning. It does not know that the New Moon on April 2 conjoins Saturn and Neptune. It does not know that Uranus enters Gemini three weeks later. It does not know that the Paschal full moon of 2026 shines over a world in which the old structures — political, financial, informational — are visibly dissolving.
Mundane astrology does not claim that the sky causes events. It claims that the sky and events share a pattern — that celestial mechanics and human history are two expressions of a single underlying structure. The computus is proof of concept. For 1,700 years, an astronomical algorithm has determined when two billion people celebrate rebirth. The Moon moves. The date moves. The ritual follows. No one disputes this mechanism. The only question is how far the mechanism extends.
Easter 2026 asks that question more sharply than any Easter in living memory. The algorithm places the resurrection inside the Saturn-Neptune seed. The ancient resurrection myths — Osiris, Attis, Adonis, Inanna — were always equinoctial, always lunar, always about something dying so that something else could live. The New Moon on April 2 is the death. Easter on April 5 is the return. What dies and what returns is the work of the next 36 years.
The computus has executed. The date is set. The sky has spoken.
