Shared Places

Where does the sky work for all of you?

Astrocartography redraws each person’s birth chart across the map of the world. Shared Places overlays your family’s maps — two to six people — and shortlists cities your family may find supportive according to astrocartography, with the reason for every pick and an honest confidence rating when a birth time is uncertain.

Step 1 · Your family

Who is moving?

Two to six people. Nicknames are fine — real names are never required, and these details stay on this device except for the calculation itself, which is not stored.

Step 2 · What matters most

Regions (optional)

I confirm I am the parent or guardian of any under-18 family member entered here, or otherwise have permission to enter these birth details.

Add at least one more family member to compare maps.

How this is calculated

For each person we compute the apparent positions of the ten chart bodies at their birth moment with an astronomical ephemeris, convert their birth time through the historical time-zone database, and draw the four traditional angular lines — MC, IC, Ascendant and Descendant — for every body. Cities are scored by their calculated distance to each line, each person is scored separately, and the family result combines everyone with the weakest member weighted heavily — no averaged birth details, no combined chart, ever.

Because Earth turns ~15° of longitude per hour, an uncertain birth time moves these lines a long way. For approximate times we calculate many possible maps and report how often a city stayed supportive across all of them — and an unknown time gets no precise ranking at all, rather than a silently assumed noon.

Line influence uses an 800 km radius — an AsterNym product convention, not a scientifically established boundary. Distances shown are calculated.

Shared Places is an astrocartography reading: a traditional interpretation of where planetary angles from several birth charts overlap. It does not establish that a city will cause an outcome or that moving there is advisable. Birth-time uncertainty can materially change the map. Consider family support, safety, schooling, healthcare, immigration rights and finances before making a relocation decision.
