Relocation Charts
Calculate relocated natal charts for different geographic locations.
Overview
Relocation charts recalculate a natal chart for a different geographic location while keeping the same birth date and time. This is useful for astrocartography and understanding how planetary energies manifest in different places.

Key Differences from Natal
- Same planetary positions: Planets don't move
- Different houses: House cusps recalculated for new location
- Different angles: ASC, MC, DSC, IC change based on location
