A sidereal birth chart with the classical apparatus around it: dashas, transits, and readings from more than one tradition. About 35 kB.
The chart
D1 Rāśi in South Indian (fixed signs) or North Indian (fixed houses) style, toggleable, on whole-sign houses — the classical Vedic default. A planet table gives sign, degree, house, nakshatra and pada, with retrogrades marked ℞.
Dasha and transit
- Vimshottari Dasha at monthly resolution: the active Mahadasha and Antardasha on a 120-year timeline strip, with interpretations covering all 108 combinations (9 grahas × 12 house placements), modified by dignity — exaltation, own sign, debilitation — and by house rulership.
- The full dasha table: the entire 120-year cycle with date spans. Tap any period to jump the transit date there.
- Gochara for any date, on a slider running from birth to 120 years on, with −1y / −1m / −1d / Now / +1d / +1m / +1y nudges.
- Gochara on dasha: where the Mahadasha and Antardasha lords are actually transiting — sign, house from the natal Moon, and whether that transit is favourable, testing, or obstructed by the classical Vedha refinement, including the Sun–Saturn and Moon–Mercury exceptions.
Nadi (Karaka Lagna)
Treats each significator’s natal sign as House 1, across all nine grahas — Jupiter (Jiva), Saturn (Karma), Venus (Kalatra), Mars (Bhratri/Bhoomi), Mercury (Vyapara/Vidya), Sun (Atma), Moon (Manas), Rahu and Ketu — each labelled with its zodiac cycle time. It shows the karaka’s own macro-cycle (Jupiter 12-year, Saturn 29.5-year, node 18.6-year returns) and the critical slow-planet contacts by conjunction, trine and opposition.
The Nadi score timeline plots a 0–100% favourability score for every Karaka Lagna from birth to 120 years, scaled to that lagna’s own maximum. Question presets — property, marriage, career, business, growth — map to the relevant karaka, and favourable windows above 70% are extracted into a list.
Method
- Ayanamsa: Lahiri (Chitrapaksha), the Government of India standard, modelled from its J2000.0 value with the IAU precession rate.
- Positions: apparent geocentric ecliptic longitude of date, minus the ayanamsa. Verified against known ephemerides — a fixed star holds a constant sidereal longitude across epochs, and the Sun matches Karka Sankranti timing.
- Rahu/Ketu: mean lunar nodes, always retrograde.
- Lagna: from local sidereal time, obliquity and latitude.

A note on the readings
The interpretive text is concise, traditional, keyword-level guidance offered for reflection — not deterministic prediction.
