Birth Chart Compatibility
A full synastry reading — not just sun signs. Enter both sets of birth details and we'll compare your complete charts: Sun, Moon, Mercury, Venus & Mars, and the aspects between them.
Step One
You
Enter your birth details
Enter the local clock time when you were born — don't adjust for daylight saving. Tick ‘Time unknown’ if you're not sure.
Step Two
Your Partner
Enter your partner's birth details
Enter the local clock time when you were born — don't adjust for daylight saving. Tick ‘Time unknown’ if you're not sure.
Birth time sharpens the result — the Moon shifts signs every ~2.5 days, so a known time refines a cusp birthday. It's optional.
