Sidereal vs tropical
Glossary · Last updated: 2026-07-26
The tropical zodiac (Western sun signs) starts Aries at the March equinox. The sidereal zodiac (Vedic) aligns to star backgrounds with an ayanamsa correction.
Neither is 'wrong' in isolation - they answer different historical questions. Comparing them side by side is educational.

Western cards use tropical sun signs. Vedic Moon and Lagna use sidereal positions. Chinese, Mayan, Celtic, Akan, and Tibetan cards use entirely different calendars.
