Sagittarius
22 November to 21 December. The archer: a fire sign that wants the bigger picture, ruled by Jupiter, the planet the tradition associates with growth, belief and range. This page is the reference, written plainly, followed by the one thing most sign pages will not tell you.
What the tradition actually says
Western astrology reads a Sagittarius Sun as an identity organised around horizon: the person is at their best when something is opening up, a subject, a country, an argument, a plan. The fire element gives directness and appetite; the mutable modality gives flexibility, which is why the tradition describes Sagittarius as the explorer rather than the general. Jupiter's rulership adds the appetite for meaning: not just going somewhere, but going somewhere that signifies.
The honest shadow readings in the classical sources are bluntness that arrives before tact, promises sized to the enthusiasm of the moment, and a restlessness that can read to others as unreliability. A sign page that only lists virtues is a greetings card; the tradition itself is more even-handed than that.
Common misreadings
Sagittarius is not "the lucky sign"; Jupiter's association is with growth, which includes growth that arrives as excess. It is not incapable of commitment; the mutable fire pattern commits readily to what keeps expanding and struggles with what has stopped. And a Sun sign describes what you are consciously building, not the whole person: your Moon, your rising sign and thirty other placements say the rest, which is why we calculate all of them.
The part other sign pages leave out
If you are a Sagittarius Sun in Western astrology, your Sun in the Vedic system is probably in Scorpio.
Western astrology anchors its zodiac to the seasons; Vedic astrology anchors its to the stars. The two rulers have drifted about 24.2 degrees apart over two thousand years, so if you were born between 22 November and 15 December, your Vedic Sun sits in Scorpio, in one of the lunar mansions Anuradha and Jyeshtha. Born 16 December to 21 December, you keep Sagittarius in both systems, in the mansion of Mula. Neither ruler is wrong. They are measuring differently, and any product that shows you only one is choosing tidiness over the whole truth.
Those dates are 2026's. The Sun reaches the sidereal boundary at 04:45 UTC on 16 December, so a birth on that day is settled by the hour and the place, and the split moves by about a day every seventy years as the two zodiacs drift apart.

Questions people ask
Is Sagittarius compatible with my sign?
Sun-sign compatibility is the postcard version: two placements out of the eighty a real pair comparison reads. The traditions also disagree with each other about pairs, which we show rather than hide. The honest answer needs both charts, and the free calculator is where it starts.
What is a Sagittarius Moon or rising?
A Sagittarius Moon reads as the emotional pattern (feelings that need room and honesty), and Sagittarius rising as the first impression and the frame of the whole chart. Same sign, three different jobs. Your own combination is on your free chart.
Which is right, my Western sign or my Vedic one?
Both. They are two internally consistent rulers laid against the same sky, about 24.2 degrees apart. What matters is knowing which one a reading is using, and what each was designed to do well.
We read charts for pattern and coherence, not prediction. Nothing here tells you what will happen, and nothing here tells you who you are; it shows a structure and leaves the judgement with you.
