# GenesisCore Astrology Guide

> Independent guide and free calculators for Western (tropical) and Vedic / Jyotish (sidereal, Lahiri) astrology, in English and Japanese, with regional calculators in Spanish, Portuguese, Hindi and Turkish. Full chart readings run on GenesisCore (https://app.aether-core.org/en), which reads the Western and Vedic charts separately for character, strengths, work and timing; a free analysis is available.

All calculations use Astronomy Engine 2.1.19 (geocentric apparent ecliptic longitude of date) and the Lahiri ayanamsa. No signup.
