Western Tropical & Vedic Sidereal Natal Chart
Oracle Spheres bridges both major astrological traditions by calculating Western Tropical Sun, Moon, and Ascendant placements alongside Vedic Sidereal (Lahiri Ayanamsa) Janma Rashi and Nakshatra lunar mansions.
Dual Western Tropical & Vedic Sidereal Birth Chart Analysis
Using astronomical orbital algorithms calibrated to your exact birth date, time, and geographic birthplace, the chart engine computes planetary longitudes in both Tropical and Sidereal zodiacs simultaneously—eliminating manual conversion confusion.
All planetary degrees, ayanamsa offsets, Nakshatra divisions, and aspect angles are calculated deterministically using orbital astronomy before any reflective interpretation is generated.
Integrates Hellenistic/modern Western Tropical ephemeris astronomy with classical Indian Jyotish (27 Nakshatras and Lahiri Chitrapaksha Ayanamsa).
Frequently Asked Questions
Why are my Western and Vedic zodiac signs different?
Western astrology aligns 0° Aries with the Spring Equinox (Tropical zodiac), while Vedic Jyotish aligns signs with fixed background star constellations adjusted by ~24° precession (Sidereal zodiac / Ayanamsa).
What if I do not know my exact birth time for a natal chart?
If exact birth time is unknown, solar-noon defaulting still gives accurate Sun degree, outer planet positions, numerology, and most Moon placements, though rising Ascendant degree requires an accurate birth time.
