Sidereal zodiac
Glossary · Last updated: 2026-07-26
The sidereal zodiac measures signs from a star-backed zero point, corrected by ayanamsa. Jyotish rashis use this system.
Your sidereal Moon sign can differ from your tropical moon sign even though both are called, for example, Cancer or Karka.
Lahiri standard
We use Lahiri ayanamsa for Vedic Moon and Lagna, matching many Indian ephemerides.
