The Two-Person Star Clock
Two birth moments on one instrument: the months, the zodiac and the 64 gates on one wheel, with each person's sky placed as beads exactly where it stood. Enter two birth moments below and watch both skies wind into place together, then see which channels complete only between you. Free, no account, and birth details are never stored.
Two birth moments
The snapshot
Hover any bead for its planet and reading; hover any gate number for its door into the library.
Only between you
These are the two birth skies alone. Each of you also carries a Design sky from about 88 days before birth; the full Connection chart weighs all four, and the Relationship reading tells the whole story.
What am I looking at?
Two birth skies, drawn on one instrument. The ring carries the twelve months, the zodiac and the 64 gates of Human Design; the beads are the Sun, Moon, planets and lunar nodes of two different birth moments, each placed exactly where it stood. Hover any bead and a dashed sight line runs to the Earth at the center: where that line meets the rim is the gate that planet activates, and the body itself surfaces beneath the bead.
Whose beads are whose?
Each person keeps a color. The bone colored set belongs to the first person, with its readings listed on the right; the red set belongs to the second person, reading on the left. Every planet appears once for each of you: two Suns, two Moons, twenty six activations between you. Where your beads share a gate, you were born under the same note of the sky.
What are the numbers around the rim?
The 64 gates of the wheel, each a slice of the sky about five and a half degrees wide, each divided into six lines. When either sky stands in a gate, the number lights gold, and its reading appears beside the wheel as gate and line: 52.1 means Gate 52, line 1. Hover any number to see which of you holds it, the gate’s name, and a door into the library.
What completes only between you?
Human Design pairs the 64 gates into 36 channels, and a channel can complete across two people: one of you holds one end, the other holds the other. When both skies are placed, the clock lists every channel your two birth skies finish together, naming whose bead supplies which gate. These are currents that exist only in the room you share; neither of you carries them alone.
Why do both skies sweep into place?
Because each sky arrived at its birth moment; it did not start there. When the clock loads two charts, every bead approaches along its own orbit at its own true pace, both skies winding at once: the Moons cross great arcs, the Suns a handful of gates, and the slow outer planets barely stir. Then everything settles together, because each birth is one instant, and the instrument holds both.
Where do the readings come from?
From the same certified engine that draws every chart on this site, computed from each exact date, time and place with Swiss Ephemeris grade precision. The clock is the display, never the calculator: after the beads settle, the page checks all twenty six readings against the engine’s own numbers before it trusts what it shows you. And this wheel holds the two birth skies themselves; each of you also carries a Design sky from about 88 days before birth, which the full Connection chart weighs alongside these.
