Understanding Your Chart

Your natal chart is divided into 12 houses, each governing a life area — from identity (1st house) to the subconscious (12th house). Planets in each house activate specific themes:

  • Sun — core identity, ego, life purpose
  • Moon — emotions, instincts, inner world
  • Mercury — communication, thinking style
  • Venus — love, values, aesthetics
  • Mars — drive, action, energy
  • Ascendant — how others perceive you

Frequently Asked Questions

What is a natal chart?

A natal chart (birth chart) is a map of the sky at the exact moment and location of your birth. It shows the positions of the Sun, Moon, and planets in zodiac signs and houses, revealing your personality traits, strengths, and life patterns.

What do I need to calculate my natal chart?

You need three things: your date of birth, exact time of birth, and place of birth. The more precise the time, the more accurate your house placements and Ascendant will be.
