FAQ
Is the couple chart comparison free?
Yes — completely free. Enter two birth dates (and optional times) to compare Big Three placements.
Is this professional synastry?
No. This is a simplified Big Three comparison for entertainment. Full synastry includes houses, aspects, and transits beyond this tool.
Do I need birth time?
Sun signs need only birth dates. Moon is more accurate with time; rising requires birth time, coordinates, and UTC offset.
