Understand the chart, one experiment at a time
Original worked examples using this calculator. Check the arithmetic, change an input, and learn where the interpretation ends.
Read a life chart without mistaking a score for a prediction
Follow one fictional input all the way from three cards to a yearly candle. Inspect the numbers yourself.
Read the worked example →Experiment 2What changes when you change a tarot card?
Hold the birth sky fixed, change one card, and see which parts of the result move and which stay the same.
Read the worked example →Experiment 3Why a Saturn return is a window, not an exact birthday
Compare the actual return rows for three birth dates and learn what the annual sampling can and cannot resolve.
Read the worked example →How to use this lab
Start with the reading walkthrough, then change one card while keeping the birth date fixed. Finish with the timing comparison. The tables use the same local engine as the free calculator and remain readable without JavaScript; the year selector becomes interactive when JavaScript is available.
These tutorials examine the behaviour of a symbolic model. They do not test whether astrology forecasts real events. Keep a record of mismatches as well as apparent matches, and use the linked methodology to distinguish astronomical inputs from our editorial scoring choices.
Sources, scope and corrections
The numerical examples are original calculations from the Life Astro Chart engine. The astronomical approximation comes from JPL’s approximate planetary positions; this source supports the position method, not the astrological interpretations. Our cross-check uses the independently maintained Astronomy Engine.
Interpretations and card weights are editorial conventions, not scientifically validated forecasts. See the full rules and limitations. Report an error with the page URL and the input needed to reproduce it through our contact page; never send sensitive personal details.
