Questions people ask
How is zodiac compatibility calculated?
+
Sun-sign compatibility looks at how far apart two signs are on the zodiac wheel (the aspect between them), whether their elements support each other, and how their modalities handle change. For a fuller picture, compare both people's Moon, Venus and Mars signs too.
Which zodiac signs are most compatible?
+
Signs in the same element (a trine) and signs two apart in complementary elements (a sextile) usually feel the easiest. Opposite signs have strong attraction with more friction. Any pairing can work; some just ask for more conscious effort.
Can I check compatibility with just birthdays?
+
Yes. Two birthdays give you both Sun signs. Adding birth times and places lets you compare Moon, Venus and Rising signs, which usually says more about day-to-day chemistry.
