Whole Sign Geocentric Birth Chart Calculator

This calculator uses Whole Sign house system and geocentric coordinate system.

Whole Sign houses is the oldest house system, used in ancient Hellenistic astrology. Each house occupies one complete zodiac sign (30°), with the sign containing the Ascendant becoming the 1st house. This system is experiencing a revival among traditional astrologers.

The geocentric system calculates planetary positions from the center of the Earth, which is the traditional and most widely used approach in Western astrology. This perspective shows the celestial bodies as they appear from Earth's center, providing the standard astrological view used by the vast majority of astrologers.
