Relocation Chart
A relocation chart preserves the same birth instant while recalculating local sidereal time, angles, and houses for a different location. Scope is explicit.
Overview
Planetary longitudes stay tied to 12:00Z while the Ascendant, MC, and house cusps are recalculated. This is the worked result for Relocation Chart; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Convert the original civil birth record once to UTC, keep planetary calculation options fixed, replace only location, and issue a receipt for both natal and relocated cusps.

Definition and exact scope
A relocation chart preserves the same birth instant while recalculating local sidereal time, angles, and houses for a different location.
Calculation or decision rule
Convert the original civil birth record once to UTC, keep planetary calculation options fixed, replace only location, and issue a receipt for both natal and relocated cusps. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.
Worked case and illustrative near miss
instant 1990-01-01T12:00Z; origin 40.7128°N 74.0060°W; destination 34.0522°N 118.2437°W. planetary longitudes stay tied to 12:00Z while the Ascendant, MC, and house cusps are recalculated.
Illustrative near miss; does not qualify: Converting 12:00Z to 12:00 Los Angeles time changes the instant and is not a relocation chart.
School, model, and context variants
Changing the time zone to the destination’s current clock changes the birth instant and is not relocation; symbolic differences do not establish relocation outcomes.
Product, safety, and verification boundary
OpenFate provides the chart inputs used by Relocation Chart, but claims no dedicated automated interpretation. Relocation Chart preserves contrary observations and uncertainty. It cannot replace consent, professional help, location research, or a person’s account.
