Relationship chart essentials
Find your relationship
placements.
Enter a birth date, place, and—if you know it—your local birth time. With a time, you get Sun, Moon, Mercury, Venus, Mars, and Rising; without one, you get a disclosed date-anchored Sun, Mercury, Venus, and Mars reference.
How to use it
Start with a useful question.
Sun sign can be a prompt for identity, Moon for comfort, Mercury for communication, Venus for affection and values, Mars for drive and assertion, and Rising for first impressions. Treat each result as a language for reflection—not a verdict about a relationship.
Reading your relationship placements
Six lenses, one person.
Your Sun sign is the piece people often know first: it can describe conscious identity and what helps you feel recognized. Moon sign is usually more private—it is useful for naming what makes you feel safe, soothed, or overwhelmed. Mercury adds communication and interpretation. Venus brings focus to affection, taste, reciprocity, and the gestures that land as love. Mars adds drive, assertion, and conflict pacing. Rising is the doorway: how you enter a room and how others may meet you before they know the rest.
Use the placements together. If your Sun wants direct expression while your Moon needs space to process, both can be true. That kind of contrast is often more useful than asking which placement is the “real” you.
Big Four calculator FAQ
Why does birth time matter?
Rising changes throughout the day, and Moon moves quickly enough that a missing or uncertain time can matter. A dated hospital or family record is worth using when you can find one.
Can I use this without a birth time?
Yes, with a narrower result. The tool uses local noon only as a disclosed date anchor for Sun, Mercury, Venus, and Mars, hides Moon and Rising, and does not show an exact natal-aspect report. The reference degrees can shift during the day, so verify sign-boundary dates if a placement is close to an ingress.
