Life is coherence that has learned to write itself into time.
One planet. One coherence.
A twenty-three-document body of philosophical, astronomical, and mathematical work — spanning calendar reform, spherical geometry, chronobiology, hemispheric astrology, and contemplative practice — built for the full human population of the Earth.
A soul-calendar anchored to the equinox.
Thirteen months of 28 days each — 52 complete weeks, no remainder, no drift. Three movements: Dissolution, Recognition, Inscription — across a 4+5+4 structure, named from six language families. Grounded in physical absolutes, not metaphor alone.
Clockwise, warm, outward. The triangle is the Northern Hemisphere's primary geometry — the form the Northern sky naturally traces. The diamonds are present as complement.
Counter-clockwise, cool, inward. The diamond is the Southern Hemisphere's primary geometry. The triangles are present as complement. Each hemisphere is primary from where it stands.
Both geometric families inhabit the same unbroken {13/5} star line simultaneously. Ophiuchus ⛎ at the center belongs to neither hemisphere — it is the convergence of both.
Zola is Earth's birthday. Ophiuchus ⛎ is its sign.
- Oct 2026 Terran Pace. Speed measured against the Sun: enter a speed, a heading and a latitude and read the solar ratio, in cells crossed per hour. Contribution 38, set out in Document XXIII. Now under Explore.
- Oct 2026 The Library. Every document of the Series in order, with its status and links: twenty-three documents, all published, and the thirty-eight original contributions listed by number. Now under The Series.
- Oct 2026 Band VII — the Solar Wind band. Live NOAA solar wind data rated against the Terran Navigation framework (Document XXI): dynamic pressure, Bz and Kp, with a five-level Launch Condition Rating on a weakest-link rule. All Time now shows all seven bands, from the hydrogen line to the solar wind, in one view.
- Oct 2026 Documents XV and XVIII to XXIII. Now published: the Terran Body, Language and Education, the Yuga, the Architecture, the Navigation, the Interval and the Measure. They record contributions 31 and 33 to 38, from the Yuga to the Terran Pace.
- Oct 2026 The Terran Measure. A measurement system grounded in the sphere: one degree of latitude as the Terran Degree, and 4,344 Terran Cells of 1° by 15° across the globe. Document XXIII, in preparation.
- Oct 2026 Foundation Day and Leap Day. Both hemispheres now share them: Foundation Day on October 14, Leap Day on October 15 only before a February 29. Both sit outside the count, directly after Zola, and the instruments now read them that way.
- Oct 2026 The Dual Zodiac portrait. Signs now follow the 28-day Terran months, and Ophiuchus governs Zola, Foundation Day and Leap Day. The Nakshatra calculation uses a precise lunar position and the Lahiri ayanamsa, and says when your date straddles a boundary.
- Oct 2026 The Martian Terran Calendar. The Earth-day version (14 months of 49 Earth days) is the primary calendar; the 19 × 35 sol version stands beside it, with a conversion table between them.
- Oct 2026 Spellings. Iḥtiwāʾ and Taḥawwul are now written the same way on every page.
Twenty-three documents. One library.
All twenty-three are published as open-access PDFs under CC BY 4.0, each with its Zenodo record and permanent DOI. Every document is listed in order in the Library, with its status and links.
The living tools.
The Terran Series is not only documents. The calendar runs. The star reveals its layers. The clocks show one planetary year from two hemispheric responses simultaneously. The Hypersphere instruments locate you on the four-dimensional manifold the Series has proven closed. Each tool is the final page of its document. The Your Terran instruments — Planner, Birth Moment, Compatibility, and Equinox Countdown — make the Series personal.
The philosophical foundation of the Terran Series — and the {13/5} star polygon that encodes its complete structure.
Read the proposition →The structural case for 13 months of 28 days — plus your Dual Zodiac, Nakshatra, and Chinese animal, corrected for your hemisphere.
Explore the calendar →The live 13-month soul arc for both hemispheres — plus this week's practice: attention, inquiry, and body gesture.
Open the calendar →When the clock says noon — where is the sun? Enter your longitude and the argument proves itself in real time.
Find your TM zone →The geometry of earthly time — six live instruments. The Latitude Clock shows day length, solar altitude, and flux at your latitude versus its mirror in the opposite hemisphere. The Day Length Calendar shows a full year of light with the 13 Terran months overlaid. The Sphere Clock shows the full rotating globe — terminator line, continent outlines, solar declination, and your personal solar noon. The Flux Calculator shows exactly how much solar energy the sphere is delivering to your latitude — with UV index, vitamin D synthesis times, and the 6.9% Southern Hemisphere perihelion advantage. The Terran Kairos shows the first derivative of day length — the rate the solar signal is changing, with a live Solar Window. Kinesis shows where you are within today’s light from sunrise to sunset, in Phases, Moments, and Pulses.
Explore the sphere →The Terran Moment reads your complete four-layer temporal portrait live — Movement, Soul Month, Kinesis, Kairos — with your position on the Terran Hypersphere (φ, λ, t‑day, t‑year) shown on a live sphere canvas. Select any two cities from 490 worldwide and see their Terran Moments simultaneously, with the Terran Metric distance between them. HALOS — Helio Axis Locus Observable Signature — names your solar identity: one of 2,808 distinct positions on the Terran Hypersphere. 490 cities, 140 countries, global facts including land vs water, the ISS, and Antarctica.
Find your Moment and HALOS →One planetary year — two hemispheric responses, ten instruments. The Infinity Clock shows one year as two rings joined at Zola ⛎. The Chronograph records time across four scales on the Soul Star face. The H Scroll and V Scroll show the year as living manuscripts. The Solar Clock (UT) expresses time in Universal Times — t:L:AA:TT. The Terran Day shows the complete 24-hour solar cycle with a full conversion table bridging your clock time to the Terran framework.
Open the clocks →The personal layer of the Series. Your day planned around the light. Your birth moment on the sphere. Your solar compatibility with another person. Your countdown to the next Terran New Year.
