Tropical Whole Sign Birth Chart Calculator

This calculator uses traditional tropical zodiac system and Whole Sign house system.

The tropical zodiac is based on the seasons and the position of the Sun at the spring equinox. This is the system used by most Western astrologers. Each sign is exactly 30 degrees, starting with Aries at the spring equinox (March 20-21).

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.
