Read a chart in layers
A planet describes a theme, a sign its symbolic style, a house a life area and an aspect the geometric relationship between two themes. Consider the four layers together rather than inferring a whole personality or life outcome from one sign. Find the exact placement in your chart first, then compare your experience with the questions in its guide.
Zodiac, astronomy and interpretation
Starmora uses the tropical zodiac: twelve equal 30-degree intervals beginning in the direction of the March equinox. These are different from the unequal boundaries of stellar constellations. Examining astronomical longitude calculations separately from historical symbolic interpretations makes it clearer what a source actually supports.
Keep settings aligned when comparing
When comparing services, align the birth UTC instant, coordinates, tropical or sidereal choice, true or mean node method and house system. Starmora explicitly offers Placidus, Whole Sign, Equal and Porphyry. A changed house number with an unchanged planetary sign is not necessarily a calculation error.

Sources and approach
Astronomy Engine supports the calculation of planetary positions. The symbolic explanations of signs, planets, houses and aspects here follow Starmora's original interpretive approach; validating an astronomical calculation does not establish these readings as measurements of personality or life outcomes.
