What is Synastry?
- You and your partner are drawn to each other, but there's so much more to your connection than meets the eye. Maybe you vibe perfectly in some ways, but in others, it feels like you're speaking different languages.
- That's where Synastry comes in. Synastry is an in-depth astrological technique focused on relationships that go beyond comparing sun signs. This overlay of your birth charts shows how the planets and positions in your individual birth charts relate, interact, and impact each other.
- When your charts are unified, the two charts, analyze how the planets align to form powerful geometric angles called aspects. Instead of waiting for your partner to change, these personalized insights guide you on how to become the partner you aspire to be loved by.
Why does Synastry matter?
- Forget swiping and settling. Your Synastry Chart reveals how YOUR unique energy dances with someone else's – it's the real deal beyond basic compatibility.
- Love Compatibility isn't about simple labels or whether you'll "work." It explores the electrifying interplay of your energies – where you ignite sparks, where you challenge each other, where you build an unbreakable bond.
- Synastry helps you build a love that grows stronger with every challenge and embrace a love that's AUTHENTICALLY, UNDENIABLY yours. Isn't that the kind of fulfilling partnership we all crave?
How to Read a Synastry Chart
Synastry compares two birth charts by mapping the aspects each person's planets make to the other's — revealing attraction, emotional needs and long-term compatibility. The strongest signals come from the personal planets (Sun, Moon, Venus, Mars) and where one person's planets fall in the other's houses.
Key synastry aspects
| Aspect | What it means | Vibe |
|---|---|---|
| Sun – Moon | Core compatibility of ego and emotions; a classic marriage aspect | Harmonious |
| Venus – Mars | Romantic and sexual chemistry, mutual attraction | Harmonious |
| Moon – Venus | Emotional warmth, affection and easy tenderness | Harmonious |
| Moon – Moon | Shared emotional style and instinctive understanding | Harmonious |
| Sun – Venus | Warmth, admiration and enjoyment of each other | Harmonious |
| Mars – Mars | Similar drive and passion; can spark or clash | Mixed |

What is a synastry chart?
A synastry chart compares two people's birth charts by mapping the aspects each person's planets make to the other's. It reveals attraction, emotional needs, friction points and long-term compatibility between two people.
How does the synastry calculator work?
Enter the birth date, time and place for both people. The calculator builds both natal charts and overlays them, showing the inter-aspects between your planets and where each person's planets fall in the other's houses.
Do I need exact birth times for a synastry chart?
The planet-to-planet aspects still work without exact times, but the house overlays and Moon placements become approximate. For the most accurate reading, use exact birth times for both people.
Which planets matter most in synastry?
The personal planets carry the most weight: the Sun and Moon (identity and emotions), Venus (love and affection) and Mars (desire and drive). Contacts between these are the heart of relationship chemistry.
Which houses matter most in synastry?
The 1st, 5th, 7th and 8th houses are the most telling. When someone's planets land in your 5th (romance), 7th (partnership) or 8th (intimacy), the connection tends to feel significant.
What is the difference between synastry and a composite chart?
Synastry compares two separate charts to each other. A composite chart merges both charts into a single new chart representing the relationship itself as its own entity. Synastry shows how you affect each other; the composite shows the relationship's own character.
Are synastry charts accurate?
Synastry is a well-established astrological technique, and with accurate birth data it reliably highlights the dynamics between two people. It describes tendencies and potentials rather than guaranteeing outcomes.
