Your decan
The first decan of Sagittarius is the sign with no filter and no ceiling — double Jupiter, pure expansion. You're the most restless, most opinionated, most genuinely hungry-for-everything slice of Sagittarius, the one who books the flight before checking their bank account and calls it faith. The horizon doesn't just beckon; it physically won't let you sit still.
What sets your third apart
Because Jupiter rules both the sign and this decan, there's no second planet to add focus, patience, or a sense of consequence. It makes you the most magnetic and alive of the three Sagittarius decans — and the most likely to overpromise, over-wander, and mistake enthusiasm for a plan. The other two decans get a sub-ruler that eventually says 'enough'; you don't.
Your gift
Genuine belief that something better exists out there — and the nerve to go find it.
Your watch-out
Jupiter doubled means excess doubled; you call it vision when it's actually just refusing to commit.
The exact degrees, and who rules them
A decan is a third of a sign: ten degrees of zodiac, not a mood. Yours is Sagittarius 0°00′ to 9°59′ — the first ten degrees the Sun crosses on its way through Sagittarius, roughly Nov 22 – Dec 1 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) | Jupiter | The baseline Sagittarius everyone shares |
| Chaldean face | Mercury | mind, language and exchange |
| Triplicity decanate | Jupiter | growth, meaning and excess |
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 (Jupiter) without saying so; the older Sagittarius face here is Mercury.
Read either way, the point is the same: scale — this third overshoots where the rest of the sign would stop.
How it actually shows up
The decan is a modifier, not a second sign. It shifts emphasis inside Sagittarius rather than replacing it — so everything true of Sagittarius is still true of you, with growth, meaning and excess turned up. Three places people notice it:
- Under pressure. A Sagittarius sun typically leaves the room, literally or not. In this third that reaction takes its colour from Jupiter — growth, meaning and excess is what the reaction ends up being about.
- In how you start things. The first decan sits at the front of the sign, where its qualities are least diluted and most raw.
- Next to the other two. Compare it directly: the second decan (Dec 2 – Dec 11) runs on Mars, and the third decan (Dec 12 – Dec 21) runs on Sun. 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.
