♋ 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.
In the tradition
| Ruler | Moon |
| Exalted here | Jupiter |
| In detriment | Saturn (it rules the opposite sign) |
| In fall | Mars (exalted opposite) |
| Body-map | 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.
The three decans
| Decan | Chaldean face | Triplicity ruler |
|---|---|---|
| 0°–10° | Venus | Moon |
| 10°–20° | Mercury | Mars |
| 20°–30° | Moon | Jupiter |
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.
