The calculator starts with your birth date, birth time, birthplace, and timezone. After the map is generated, city checks, Best Time to Move, and reports use that calculated chart as their foundation.
Before writing any conclusion, a Personal Astrocartography Report cross-checks ordinary planetary lines, major angle aspects, Parans, relocated charts, natal modifiers, and birth-time sensitivity. Place rankings, the web report, PDF, and AI follow-up use the same calculated result. AI can explain the result, but it cannot change the ranking or invent evidence.
Best Time to Move scans the next 12 months for a selected city and goal using transits, the relocated chart, secondary progressions, solar arcs, and solar returns. The result is calculated before any AI explanation.
