How relocation works
A relocation chart applies the original birth instant to a new longitude and latitude. The Ascendant, Midheaven, and houses are calculated for that destination. In this geocentric method, the planets keep their natal zodiac positions and may fall in different houses.
The comparison uses the selected Whole Sign, Equal House, Porphyry, Placidus, Campanus, or Regiomontanus system. Placidus, Campanus, and Regiomontanus show a labeled Porphyry fallback where their cusps are unavailable. An uncertain birth time makes angles and houses unreliable; an incorrect historical UTC offset shifts the entire comparison.
