Tropical Equal House Birth Chart Calculator

This calculator uses traditional tropical zodiac system and Equal 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).

The Equal House system divides the chart into twelve equal 30-degree houses, starting from the Ascendant. This simple and ancient system treats all houses equally and is popular among astrologers who prefer a straightforward approach to house division.
