Placement library FAQ
What ephemeris does Natal Blueprint use for chart calculation?
Natal Blueprint calculates every chart with Swiss Ephemeris — the same high-precision astronomical engine used in professional astrology software — so planetary longitudes, house cusps, and aspects reflect observatory-grade positions rather than approximations.
What is the difference between a planet in a sign and a planet in a house?
A planet in a sign describes how that drive expresses — its style, tone, and motivation. A planet in a house shows where in life that energy becomes most visible. Both layers are required for accurate interpretation; neither replaces the other.
Why read a full natal chart instead of one placement page?
Single-placement pages isolate one factor. A full natal chart reading integrates sign, house, aspects, dignities, fixed stars, and timing so the same placement means something different in every unique chart architecture.
