What is a Birth Chart?
A birth chart (also called a natal chart) is a snapshot of the sky at the exact moment and location of your birth. It maps the positions of the Sun, Moon, and planets across the 12 zodiac signs and 12 houses, creating a unique cosmic fingerprint that influences your personality, relationships, career, and life path.
Unlike your daily horoscope (which only considers your Sun sign), your birth chart reveals the complete astrological picture. It shows where every planet was positioned when you were born, including aspects (angular relationships between planets) that add depth and nuance to your cosmic blueprint.
What's Included in Your Birth Chart
☀️ Sun, Moon & Rising Signs
Your "Big Three" - the foundation of your astrological identity. Sun = core self, Moon = emotions, Rising = outer personality.
🪐 Planetary Positions
All 10 planets (including Chiron) with their exact zodiac positions, revealing different aspects of your personality and life themes.
🏠 House Placements
The 12 houses represent different life areas (career, relationships, home, etc.). Planets in houses show where their energy manifests in your life.
📐 Aspects & Patterns
Angular relationships between planets (conjunctions, trines, squares, etc.) that reveal how different parts of your personality interact.

How to Read Your Birth Chart
Reading a birth chart can seem overwhelming at first, but it becomes easier when you break it down into layers. Start with your Big Three (Sun, Moon, Rising), then explore your personal planets (Mercury, Venus, Mars), followed by social planets (Jupiter, Saturn), and finally outer planets (Uranus, Neptune, Pluto).
Each planet represents a different facet of your personality and life. Mercury governs communication, Venus rules love and values, Mars shows your drive and passion, Jupiter brings expansion and luck, Saturn teaches lessons and discipline, while the outer planets influence generational themes and transformation.
The houses show where these planetary energies play out in your life. For example, Venus in the 7th house emphasizes partnerships and relationships, while Mars in the 10th house drives career ambition. SelfChart provides detailed, AI-powered interpretations for every placement in your chart.
