GetBirthChart

GetBirthChart is an online birth-chart calculator and interpretation tool for exploring your Sun, Moon, and Rising sign (where available), plus planets, houses, and aspects.

Enter your birth date, time, and place to calculate planetary positions and chart structure from professional ephemeris data, including a transparent house system. Then use the interpretation layer to understand how your chart factors connect into clearer, more practical themes.

If you don’t know your exact birth time, GetBirthChart leaves out time-dependent elements such as the Ascendant and houses rather than guessing. The calculation layer is separated from the AI interpretation layer, and the core Python engine is published as the open-source gbc-astro project for transparency and reproducibility.

What does GetBirthChart calculate for my natal chart?

It calculates planetary positions, chart houses/angles, and aspects from your birth date, birth time, and location, then provides an interpretation that explains how the placements connect.

Do I need my exact birth time to get a full chart?

No—if you don’t know your exact birth time, GetBirthChart omits time-dependent results like the Ascendant and houses instead of guessing them.

What is included in the “Big Three” on GetBirthChart?

The Big Three are the Sun, Moon, and Ascendant. Sun and Moon can be interpreted from your date/time data, while Rising depends on having an exact birth time.

How does the interpretation relate to the calculated chart data?

GetBirthChart uses one layer to compute chart data (positions, houses, aspects) and a separate AI interpretation layer to explain the connections between those chart factors.

What tools are available beyond a natal chart?

You can explore calculators and chart views such as Big Three, Moon sign, Rising sign, Venus sign, Mars sign, compatibility & synastry, and yearly forecast tools.
