Equal House Topocentric Birth Chart Calculator

This calculator uses Equal House system and topocentric coordinate system.

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.

The topocentric system calculates planetary positions relative to the observer's location on Earth's surface, rather than from Earth's center (geocentric). This results in slightly different positions, particularly for the Moon, and is preferred by some astrologers for its physical accuracy.
