Frequently asked questions
How is zodiac compatibility worked out?
This calculator uses the classic astrological approach: how far apart two signs are on the zodiac wheel (their "aspect") and whether their elements get along. Signs four apart (trine) share an element and are considered the most harmonious; signs three apart (square) are considered the most challenging.
Which elements are compatible?
Fire and Air signs fuel each other, and Earth and Water signs nourish each other. Signs of the same element usually understand each other easily.
Can a "bad" match still work?
Absolutely. Sun signs are only one small part of astrology, and real relationships depend on communication, respect and shared values. Treat this as a fun conversation starter.
Do I need birth times?
No. This calculator only uses sun signs, which come from birthdays. A full synastry reading compares entire birth charts and needs birth times and places.
What does "opposites" mean?
Signs six apart sit opposite each other on the wheel, like Aries and Libra. Opposites often feel a strong attraction and balance each other, but may need to work at understanding.
