Decan 1 · 1–10°
Sub-ruler: Jupiter
Double Jupiter — the most expansive, optimistic and excessive.
Roughly the first ten days of the sign.
November 22 – December 21 · Fire · Mutable · ruled by Jupiter
Expansion, honesty and appetite for the unfamiliar.
Calculated, not approximated
Every other site prints "November 22 – December 21" with a note that dates "may vary by a day". They vary because the Sun crosses the boundary at a specific moment, and that moment shifts each year — but it is not unknowable.
The figures above are computed: the Sun enters Sagittarius when its ecliptic longitude reaches 240°, and that crossing is found to the minute. If you were born near a boundary, this is the answer you actually needed.
Rarely covered
Each sign divides into three ten-degree segments, and each has its own sub-ruler. Two people can both be Sagittarius and read as noticeably different because they fall in different decans — roughly, early, middle or late in the sign.
Decan 1 · 1–10°
Double Jupiter — the most expansive, optimistic and excessive.
Roughly the first ten days of the sign.
Decan 2 · 11–20°
Sharper and more competitive. Drive with a target.
Roughly the middle ten days of the sign.
Decan 3 · 21–30°
Warm and idealistic. The teacher of the three.
Roughly the last ten days of the sign.
Genuinely open-minded and hard to discourage. Says the thing nobody else will.
Says it without checking whether it needed saying, and leaves before the consequences land.
Sagittarius is the one mutable fire sign — and that pairing is the whole explanation. The element sets temperament: fire signs act first and consider afterwards. The modality decides what happens when circumstances change: mutable signs adapt to it.
There are exactly twelve combinations of four elements and three modalities, and each is occupied by one sign. That is why no two signs are interchangeable, and why Sagittarius cannot be swapped for the other fire signs without changing the meaning.
Blunt, restless and genuinely open-minded. Says the thing, then leaves.
Independent and adventurous. Reads possessiveness as a threat rather than devotion.
Worth saying plainly: nothing in astrology assigns different meanings to a sign by gender. These descriptions reflect how the traits are conventionally written about, not a separate system — and plenty of people will recognise themselves in the other one.
Needs room and honesty. Reads possessiveness as a threat rather than devotion.
Great company, hard to pin down. Turns a coffee into a three-day trip.
Good with big-picture strategy, teaching and anything international. Bored by detail.
Travel, teaching, publishing, law, anything international or philosophical.
Optimistic and loose with it. Gambling instinct, in the broad sense.
Energetic, curious and needs space. Confinement produces rebellion quickly.
Fun, honest and encouraging of independence. Weak on routine.
Hips, thighs and liver — Sagittarius rules them, and overindulgence is the traditional risk.
Ranked by the angle between the two signs on the wheel — the same geometry astrology uses for aspects. Signs 120° apart share an element and form a trine; 90° apart is a square. Nothing here is a matter of opinion.
| With | Aspect | Angle | Score | Element |
|---|---|---|---|---|
| ♈ Aries | Trine | 120° | 88% | Fire |
| ♌ Leo | Trine | 120° | 88% | Fire |
| ♎ Libra | Sextile | 60° | 82% | Air |
| ♒ Aquarius | Sextile | 60° | 82% | Air |
| ♐ Sagittarius | Conjunction | 0° | 78% | Fire |
| ♊ Gemini | Opposition | 180° | 75% | Air |
| ♍ Virgo | Square | 90° | 62% | Earth |
| ♓ Pisces | Square | 90° | 62% | Water |
| ♏ Scorpio | Semi-sextile | 30° | 58% | Water |
| ♑ Capricorn | Semi-sextile | 30° | 58% | Earth |
| ♉ Taurus | Quincunx | 150° | 55% | Earth |
| ♋ Cancer | Quincunx | 150° | 55% | Water |

Lists like this are the weakest evidence in astrology and the most quoted. With roughly a twelfth of all people in any sign, every sign has impressive members — picking four of them proves nothing. Read it as trivia, not as support.
November 22 – December 21 as usually published. In 2026 specifically the Sun enters on 22 November am30 07:29 UTC and leaves on 21 December pm31 20:54 UTC.
By aspect, Aries, Leo, Libra. Those sit at the easiest angles on the wheel — but sun signs are one factor of many, and a difficult angle describes friction rather than failure.
A ten-degree third of the sign with its own sub-ruler: Jupiter, Mars, Sun. It is why two people of the same sign born three weeks apart can read quite differently.
Hips, thighs and liver — Sagittarius rules them, and overindulgence is the traditional risk.
Not in the system itself — astrology assigns no gendered meaning to a sign. The separate descriptions above reflect convention in how signs are written about, nothing more.
