♊ Gemini

mutable air · Sun in Gemini: May 21 – June 21, 2026 (computed from the ephemeris)

Gemini is the year learning to talk: mutable air at the end of spring, ruled by Mercury, the planet of language, traffic and exchange. The twins are the tradition's emblem for a mind that must hold two of everything — both sides of the question, both halves of the conversation. No planet is exalted in Gemini; it is nobody's throne room, which suits a sign that prefers circulation to occupancy.

At its best the style is quick, funny and genuinely curious. The familiar failure is breadth without weight — the tab left open, the thread dropped. The classical body-map gives Gemini the hands, arms and lungs: the organs of grasping and of speech.

Every fact above is read from the same dignity tables the chart engine uses — the reference cannot drift from the math.

The three decans

Two systems, honestly both: the Chaldean faces walk the seven classical planets in slowest-to-fastest order continuously through all 36 decans; the triplicity decans hand each third to the ruler of the next sign of the same element.

The axis, and the sign's kin

Gemini faces Sagittarius across the wheel; the axis is about facts and meaning: the collected detail against the pattern it was collected for.

Same element (air triad): Libra · Aquarius. Same modality (mutable cross): Virgo · Sagittarius · Pisces.
