Vedic Chart Calculations, Made Clear and Inspectable.

AstroSutra separates chart calculation from interpretation. Swiss Ephemeris provides planetary positions; Lahiri ayanamsa places them in a sidereal chart. Code then applies classical Jyotish methods such as Shadbala planetary strength, Ashtakavarga, divisional charts, and Dasha timing. This makes the numerical result reproducible for the same birth inputs. Tests and reference comparisons check the calculation pipeline; they do not prove that a life event will occur.

Birth-time accuracy matters, especially for house positions, higher divisional charts, and timing analysis. The depth of a reading should reflect the quality of the supplied birth details. Learn about divisional charts, compare the available plans, or try the free Moon Sign Calculator.
