Cancer — The Crab
A Moon-ruled water sign, Cancer holds the nurturing, protective energy of midsummer. As a cardinal sign it is traditionally read as one that leads through feeling and care rather than force. In astrology it is tied to home, family, memory, and emotional depth. It is often seen as the caretaker of the zodiac, fiercely loyal to the people and places it loves.

The myth underneath
Linked to the crab sent against Heracles in Greek myth.
Tradition pairs Cancer most easily with Scorpio, Pisces, Taurus — a folk pattern about temperaments, not a rule about people.
When the Sun is actually here
Across a century of computed positions, the Sun holds Cancer from about June 22 to July 22.
The edges, honestly
Sign boundaries are not fixed calendar dates — the Sun's ingress moves by a day or so from year to year. Computed across 1930–2030, these dates near Cancer's edges belong to different signs in different years:
| Date | Usually | Sometimes |
|---|---|---|
| June 21 | Gemini in 61% of years | Gemini otherwise |
| July 22 | Cancer in 93% of years | Leo otherwise |
| July 23 | Leo in 85% of years | Leo otherwise |
Born on one of these dates? The year decides. Compute your chart and the question closes in a second.
