Lahiri Koch Birth Chart Calculator

This calculator uses Lahiri sidereal zodiac system and Koch house system.

The Lahiri ayanamsa is the official sidereal zodiac system of India and is widely used in Vedic astrology. It measures the precession of the equinoxes from a fixed point in the constellations, currently placing the vernal point at approximately 24° behind the tropical zodiac.

The Koch house system, developed by Walter Koch, is a quadrant system that divides houses based on the great circles through the east point and the MC. It is popular in German-speaking countries and among some modern astrologers for its focus on individual birth time accuracy.
