Are you sure you are Cancer and Cancer?

Sun-sign dates shift by a day or two from year to year, so the ranges printed on most sites — including the conventional Jun 21 – Jul 22 in the summary above — are a rounded average, not the real boundary. Cancer season has begun on 3 different calendar days since 1930, and the Sun last actually entered Cancer on the conventional date in 2026. If either birthday falls near a boundary, check the exact year below — and if it is the boundary day itself, the free birth chart settles it to the minute.

Cancer scores highest with Scorpio (85%), Pisces (83%), Taurus (82%). The most challenging pairing is Sagittarius (47%). Cancer sits at #5 of 12.

Both are Cardinal signs, so they approach change at the same speed and can deadlock instead of one leading. On the elements: Same element (Water) — instinctive understanding and easy emotional flow. Cancer is ruled by the Moon and Cancer by the Moon, which is where their instincts about pace and priorities diverge. Their lowest score is 70%, so that is the area to work on deliberately.

Their love score (80%) runs ahead of their friendship score (75%), so the attraction arrives faster than the companionship; the long-term work is building the friendship underneath it. Same polarity (Yin / receptive) — a shared fundamental orientation. Sun signs describe roughly a twelfth of a chart, though — Moon, Venus and Mars placements decide far more of how a real relationship runs.
