♋ Cancer

cardinal water · Sun in Cancer: June 21 – July 22, 2026 (computed from the ephemeris)

Cancer begins at the summer solstice, when the Sun stands still at its height and turns back — and the sign inherits that gesture: reaching the peak, then turning toward home. Cardinal water ruled by the Moon is feeling that acts — protection, provisioning, memory put to work. Jupiter is exalted here: the tradition's way of saying generosity grows best in soil that feels safe.

The strength is loyalty with a long memory; the shadow is the same memory used as a fortress, or a ledger of grievances. The crab's sideways walk is the sign's honest self-portrait — indirection in defence of something soft. The body-map gives Cancer the chest and stomach.

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

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

Cancer faces Capricorn across the wheel; the axis is about home and work: the life that shelters you against the life that measures you.
