In Vedic (sidereal) astrology the Sun is in Dhanu from about 15–16 December to 14–15 January; in Western astrology the tropical "Sun in Sagittarius" runs from 21–22 November to 21–22 December. So a Western Sagittarian usually has the Sun in sidereal Scorpio, and a Vedic Sagittarius Sun belongs mostly to people who read Capricorn in Western horoscopes. The Sun in Sagittarius places the planet of the soul in the fire sign of its friend Jupiter: the self is drawn to principle, teaching, faith and the long view.
The archer's aim
Sagittarius is a fire sign, dual (dvisvabhava), odd and masculine, ruled by Jupiter. Its symbol is an archer, half man and half horse, aiming high. It is the 9th sign of the kalapurusha, linked with the thighs, with dharma, the father and teachers, higher learning, pilgrimage and fortune. Fire meets fire, and the Sun, itself a karaka of the father and of the 9th house, feels at home in this sign's themes.
Traits commonly seen:
- Conviction. The self is organised around beliefs, ethics or a philosophy of life.
- A teacher's authority. The person tends to lead by explaining why, not just what.
- Respect for tradition and elders, and sometimes a strong, formative relationship with the father or a guru figure.
- Restlessness. A dual fire sign wants movement, travel and new horizons; the risk is preaching or overconfidence in one's own rightness.
Tradition connects Sagittarius with the thighs; that is a symbolic mapping.
Dignity: a friend's sign
Throughout its 30° Sagittarius is a friend's sign for the Sun. Brihat Parashara Hora Shastra lists Jupiter among the Sun's natural friends, and Jupiter returns the regard. The pairing is one of the most harmonious in the zodiac: the royal planet hosted by the planet of wisdom.
Jupiter's own condition still shapes the result. A strong Jupiter lets the Sun's authority carry wisdom and generosity; a weak or afflicted Jupiter can leave conviction without depth. The Sun leaves this sign on Makar Sankranti, when it crosses into Capricorn.
Mula, Purva Ashadha and Uttara Ashadha
- Mula (0°–13°20′, lord Ketu): the root. A searching, uprooting energy that wants to reach first principles. The Sun here can be radical in the literal sense, questioning foundations; Ketu adds detachment.
- Purva Ashadha (13°20′–26°40′, lord Venus): the invincible. Confidence, persuasion and a refusal to be defeated. Venus is the Sun's enemy, so pride and pleasure can pull in different directions.
- Uttara Ashadha, pada 1 (26°40′–30°, lord Sun): the later victory. The Sun in its own nakshatra, principled and enduring, with a sense of lasting achievement.
By house: count from your lagna
- Sagittarius lagna: the 1st house, with the 9th lord in the lagna. Fortune supports the person's own direction.
- Aries lagna: the 9th house, Sagittarius's natural house, with the 5th lord there: two trikona themes linked. See Sun in the 9th house.
- Pisces lagna: the 10th house with digbala, the 6th lord at the top of the chart. Competitive or service-based careers do well; see Sun in the 10th house.
- Leo lagna: the 5th house, the lagna lord in a trikona, a much-valued placement for intelligence and children.
- Scorpio lagna: the 2nd house, with the 10th lord among family and wealth.
- Gemini lagna: the 7th house, with the 3rd lord facing the lagna.
From Sagittarius the Sun's full aspect (drishti) falls on Gemini, Mercury's sign.
The transit: Dhanu and kharmas
The Sun's gochar through Sagittarius lasts about 29 days, the shortest of its twelve stays in the sidereal signs. The period is observed in many North Indian households as kharmas, a month for devotion when weddings and similar ceremonies are usually postponed; in the South the same solar month is Dhanurmasa, known for early-morning worship. These are customs attached to the transit, not effects on individual charts. Personally, read the Sun's passage from your Moon sign, favouring the 3rd, 6th, 10th and 11th.

Where schools differ
Brihat Parashara Hora Shastra's friendship table makes the Sun and Jupiter friends without qualification, and no major school disputes that. The real disagreement is about the zodiac itself. Western astrologers tie Sagittarius to the season before the December solstice; Vedic astrologers tie it to the stars, using an ayanamsa (this site uses Lahiri). Both are consistent systems, but a reading built on one cannot simply borrow the other's sign. Later classical texts describe the Sun in Sagittarius as respected, principled and fond of learning; treat that as a sketch the rest of the chart fills in.
Common misreadings
- Confusing the tropical and sidereal signs. Most Western Sagittarians are Vedic Scorpio Suns; see Vedic vs Western sun sign and the sidereal zodiac.
- Calling kharmas "inauspicious for everyone." It is a calendar convention for ceremonies, not a forecast.
- Reading the Sun alone. The lagna, conjunctions, navamsa and the running dasha all change the picture.
