Every calculator

Understand yourself: core charts and systems

The engines everything else is built on. Each computes from your birth moment and shows its working, and each states the conventions it uses.

Understand people and relationships

What they all have in common

The calculator results are deterministic: AsterNym does not ask a language model to invent your placements, numbers or rankings at runtime. The underlying positions, dates and arithmetic are computed. Traditional interpretations are labelled as tradition; where AsterNym adds its own scoring rule or synthesis, we label that too.

AsterNym separates calculation from interpretation. Planetary positions, dates, digit sums and chart structures are computed deterministically. The meanings attached to them come from named traditions, and some scoring systems are AsterNym's own documented synthesis. When traditions disagree, we show the disagreement rather than quietly averaging it away.
