Your Birth Chart
What Is a Birth Chart?
A birth chart (also called a natal chart) is a map of the sky at the exact moment and location of your birth. It shows where the Sun, Moon, and planets were positioned across the zodiac signs and houses, revealing your core personality, emotional patterns, communication style, relationship needs, and life themes.
How AstraTalk Calculates Your Chart
AstraTalk uses your birth date, time, and location to generate a precise natal chart using Swiss Ephemeris calculations — the same astronomical data used by professional astrologers worldwide.
What You Need
| Data | Effect on Chart |
|---|---|
| Birth date | Sun sign, Moon sign, planet positions |
| Birth time | Rising sign, house placements, exact Moon degree |
| Birth location | House cusps, local horizon calculations |
If you don't have your birth time, AstraTalk still generates a chart — but rising sign and house placements will be marked as "unknown" rather than guessed.

Planet Placements
Each planet in your chart represents a different dimension of your personality:
- Sun — Core identity, ego, vitality

- Neptune — Imagination, spirituality, illusion
- Pluto — Transformation, power, rebirth
Houses (Requires Birth Time)
The 12 houses represent different life areas — from identity (1st house) to career (10th house) to spirituality (12th house). Which planets fall in which houses reveals where their energy plays out most strongly in your life.
Aspects
Aspects are angular relationships between planets. Conjunctions, trines, squares, and oppositions reveal inner tensions, natural gifts, and growth edges.
