Private and accurate

Private by design: everything is calculated in your browser. Your birth details are not uploaded, stored or tracked. The only link out is the optional button below the result, which opens the Navagraha app with your details in its address, and only if you click it.

Every figure on this page is calculated in your browser with the same shared astrology library that powers the Navagraha app. Planet positions come from the astronomy-engine library (arc-second class accuracy for the Sun and Moon) and are shifted to the sidereal zodiac with the Lahiri (Chitrapaksha) ayanamsa, the standard used by the Government of India and by the Swiss Ephemeris. In practice this agrees with Swiss Ephemeris results for signs, nakshatras and padas, apart from the rare case where a planet sits within a few arc-seconds of a boundary.

Rahu and Ketu use the true node, as in the app; many printed almanacs use the mean node, which can differ by up to about 1.7 degrees. Houses are whole-sign. Vimshottari dasha years are 365.25 days long. If you compare with another site and see a small difference, the node type, the ayanamsa or the birth-time rounding is almost always the reason.
