Your sky. Your moment. Your story.
About Nativitas
Astronomy as a foundation. Tradition as a subject of exploration.
Nativitas is a project by Alexander Ferrari Miller, created to explore the sky at a particular place and moment, and the meanings people have attached to it.
Accurate Astronomy
The starting point is a calculation: where were the celestial bodies at the time and place you enter? Ephemera explores celestial positions and local rise and set times. Natal brings a birth moment into a chart, while Synastry compares two birth charts.
Dates, times and locations matter. An uncertain birth time limits what can be said precisely about a chart. Nativitas aims to make its calculation methods and assumptions clear so you can understand the results.
Traditions & History
Alongside the astronomical calculations, Nativitas explores astrology as a historical and cultural tradition: how people interpreted planets, signs, houses and the relationships between them.
Interpretations are presented as traditional readings, with historical sources alongside them where used. These readings offer a way to explore the tradition and reflect on its ideas. Astrology's claims about personality and future events have not been scientifically validated.
Accessible by Design
A useful free experience is central to Nativitas. You should be able to explore your birth sky and obtain a basic natal chart for free.
