Cancer First Decan
The Cancer first decan (Jun 21–Jul 1) is double-Moon — the most nurturing, sensitive, and emotionally deep expression of Cancer.
The first decan of Cancer runs from roughly June 21 to July 1, the first 10° of the sign. Cancer is ruled by the Moon, and the first decan doubles that rulership — making this the purest Cancer: nurturing, intuitive, and ruled by the tides of feeling. People here embody the zodiac's instinct to protect, care for, and belong.
Double-Moon energy makes this decan the most emotionally attuned slice of an already sensitive sign. These are the natural caretakers and home-makers who feel everything and remember everything, devoted to family and the people they've taken in. Tender and protective, they lead with the heart. The shadow is moodiness and a tendency to retreat into the shell when hurt.
A Sun, Moon, or rising in Cancer's opening degrees is the crab at its most lunar — double-Moon water ruled entirely by feeling, memory, and the instinct to care.
