How our Vedic (Jyotish) chart is computed.
1. Moment of birth
As in our Western chart, clock time is converted to universal time with your birthplace's historical time zone and daylight saving rules.
2. Chart rules
Positions come from a high-precision ephemeris, converted to the sidereal zodiac with the Lahiri ayanamsa. Houses are Whole Sign from the Lagna (Ascendant), Rahu and Ketu use the mean node, the 27 nakshatras and their padas come from the Moon's longitude, and the Vimshottari dasha runs from the Moon's nakshatra at birth. Divisional charts D9 and D10 are included.
3. How we check it
We checked 13 sets of birth data against established Jyotish software: planet positions agree to within one arcsecond, and signs, houses, nakshatras and dasha dates all match.
4. How we read it
Readings explain each placement in plain words and show which planet, house or dasha they come from. No predictions about illness, death or lawsuits, and no paid remedies.
FAQ
Which ayanamsa do you use?
Lahiri (Chitrapaksha), the most widely used ayanamsa. It shifts signs by about 24° compared with Western charts today.
Mean or true node?
Mean node for Rahu and Ketu.
Why is my Moon sign different from my Western sign?
Because Vedic astrology measures against the fixed stars (sidereal), about 24° behind the tropical zodiac. Many planets move back one sign.
