Open calculatorYour chart is more than your Sun sign

Your Sun sign is one part of the picture. The Moon, Ascendant, planets, houses and aspects describe different layers of the chart and become more useful when read together.

Built for trust
Clear calculations. Clear limits.
AstroZora is built to separate astronomical calculation from interpretation, document its methodology and show uncertainty instead of inventing precision.
Calculation-first
Planetary positions, houses, angles and aspects come from the calculation engine, not generative text.
Methodology visible
Zodiac, house-system, aspect and uncertainty rules are documented so results can be understood and reviewed.
Privacy-conscious
Personalized results are designed as session experiences rather than public, indexable birth-data pages.
