Your decan
The second decan of Cancer takes the Moon's softness and runs a Mars-Scorpio current underneath it. You feel as deeply as any Cancer, but there's steel here the other two decans don't have — you protect what's yours with something closer to ferocity than tenderness.
What sets your third apart
Mars, by way of Scorpio, gives this watery decan teeth. Your moods aren't just felt, they're powerful; your loyalty carries an intensity that can tip into possessiveness or a long, quiet grudge. You don't just retreat into the shell — you defend it.
Your gift
Emotional depth backed by real spine — you feel everything and still fight for it.
Your watch-out
Hurt curdles into intensity; you guard and brood instead of just saying you're wounded.
The exact degrees, and who rules them
A decan is a third of a sign: ten degrees of zodiac, not a mood. Yours is Cancer 10°00′ to 19°59′ — the second ten degrees the Sun crosses on its way through Cancer, roughly Jul 2 – Jul 12 in most years. Sun-sign dates shift by up to a day between years because the tropical year is not a whole number of days, so if you were born within about 24 hours of either end, run the actual chart rather than trusting a date table.
| Tradition | Ruler | What it governs |
|---|---|---|
| Sign ruler (all three decans) | Moon | The baseline Cancer everyone shares |
| Chaldean face | Mercury | mind, language and exchange |
| Triplicity decanate | Mars | drive and confrontation |
The two systems disagree, which is normal and worth knowing: the Chaldean faces run the seven classical planets in speed order straight through all 36 decans without regard to sign boundaries, while the triplicity decanates give the first third of every sign to its own ruler and then step through the other signs of the same element. Most popular astrology quotes the triplicity ruler (Mars) without saying so; the older Cancer face here is Mercury.
Read either way, the point is the same: urgency — this third of the sign starts sooner and argues quicker than the other two.
How it actually shows up
The decan is a modifier, not a second sign. It shifts emphasis inside Cancer rather than replacing it — so everything true of Cancer is still true of you, with drive and confrontation turned up. Three places people notice it:
- Under pressure. A Cancer sun typically withdraws, and remembers everything. In this third that reaction takes its colour from Mars — drive and confrontation is what the reaction ends up being about.
- In how you start things. The second decan sits in the middle of the sign, the most settled and least extreme of the three.
- Next to the other two. Compare it directly: the first decan (Jun 21 – Jul 1) runs on Moon, and the third decan (Jul 13 – Jul 22) runs on Jupiter. Same sign, three noticeably different settings.
What it is not: a personality test, and not something to weigh against your Moon or rising, both of which say considerably more about you than a third of your sun sign does. The big three is where to look next.
Your decan is a hint. Your chart is the answer.
The decan refines your sun sign — but your moon, rising and every planet are where the real story lives. Run your full birth chart, free.
Degree ranges are exact by definition (each decan is ten degrees of zodiac); the calendar dates shift by up to a day between years. Rulerships are the classical Chaldean face and triplicity decanate assignments, both stated above.
