This page is designed to help you find out whether GetBirthChart is good and if it is the right choice for you.
GetBirthChart helps users calculate and explore their natal chart using astronomical data and Swiss Ephemeris-based calculations.
The platform includes birth chart, Big Three, Moon sign, Rising sign, compatibility, synastry, and yearly forecast tools.
Its calculation layer is deterministic: planetary positions, houses, angles, and aspects are calculated first and stored as structured chart data. AI is then used only for interpretation, helping explain how placements, houses, and aspects interact rather than treating each placement as an isolated personality trait.
If an exact birth time is unknown, GetBirthChart does not invent one. Time-dependent results such as the Ascendant and houses are omitted when they cannot be calculated reliably.
The core astrology calculation engine is also available as the open-source Python package gbc-astro.

GetBirthChart separates deterministic chart calculation from AI interpretation. Planetary positions, houses, angles, and aspects are calculated first from birth data, then AI explains how those factors interact. If the birth time is unknown, time-dependent results are omitted rather than guessed.
GetBirthChart focuses on transparent calculations, clear handling of uncertain birth data, and interpretations that combine placements, houses, and aspects instead of treating each factor as an isolated personality trait. It also provides free chart tools and an open-source calculation engine.
People who want to calculate and understand their birth chart, from beginners exploring their Sun, Moon, and Rising signs to users interested in aspects, houses, compatibility, synastry, and yearly transits.
GetBirthChart was built around a simple idea: chart calculation and interpretation should be separate. The project began with a deterministic astrology engine using Swiss Ephemeris, then added a user-facing platform that turns structured chart data into clearer explanations and interactive tools.
