Astrology calculators

Five instruments, one calculation engine. Exact positions come from Swiss Ephemeris; tropical and Lahiri sidereal results are labelled rather than blended.

01Birth chart calculatorA tropical chart wheel and houses, plus Lahiri sidereal planet positions, lagna, Moon nakshatra and dashas — all computed with Swiss Ephemeris.02Moon sign calculatorThe Moon moves about a degree every two hours. StarScore returns both zodiac systems instead of pretending there is only one answer.03Rising sign (ascendant) calculatorThe ascendant anchors the house wheel and changes sign roughly every two hours, so an accurate clock time and birthplace are essential.04Nakshatra calculatorYour Janma Nakshatra is the 13°20′ lunar mansion containing the sidereal Moon at birth; each mansion divides into four padas.05Vimshottari dasha calculatorThe 120-year Vimshottari sequence begins at the Moon's exact position inside its birth nakshatra. The arithmetic is deterministic.06Method & sourcesCoordinate systems, aspect orbs and known limits
