Frequently asked questions
How does the love compatibility calculator work?
It calculates both birth charts and compares them (synastry). Every important pair of planets — Sun, Moon, rising sign, Venus, Mars, Mercury and Saturn — is judged on sign harmony first and then on the exact aspect between them. The result is five separate scores instead of one number.
Do I need our birth times?
No. With dates only you get the Sun, Venus, Mars, Mercury and Saturn contacts and an approximate Moon. Adding birth times and places adds the rising signs and makes the Moon exact.
What is synastry in astrology?
Synastry is the comparison of two birth charts to see how two people interact: where they flow easily (trines, sextiles), where they attract (oppositions, Venus–Mars contacts) and where they will need to work at it (squares, Saturn contacts).
Which signs are the best match?
Signs of the same element (for example Cancer and Scorpio, both water) and complementary elements (earth with water, fire with air) usually get along most easily. But the Moon, Venus and Mars matter as much as the Sun — that is why this calculator compares full charts.
Is this compatibility calculator free?
Yes — free, without registration, and nothing you enter is saved. DatePedia members can also compare charts with any other member for free.
