What is a birth chart?
A birth chart, also called a natal chart, is a map of the sky at the exact moment and place you were born. It shows which zodiac sign each planet was in and which of the twelve houses it falls in. Astrologers read it to understand your personality, strengths, challenges and the themes that shape your life.
Your Sun, Moon and Rising signs
Your Sun sign describes your core self and life purpose. Your Moon sign shows your emotional needs and what helps you feel safe. Your Rising sign, or Ascendant, is how others first see you, and it sets up the twelve houses of your chart. Together they are known as your Big Three.
Why your birth time matters
The Moon moves about 13 degrees a day and the Rising sign changes roughly every two hours, so an accurate birth time gives you the most precise chart. If you don't know your time, you can still see your planets by sign, or book a Birth Time Rectification reading to find it.
How this birth chart is calculated
This calculator uses the tropical zodiac and whole-sign houses, with planetary positions computed from astronomical data and checked against professional astrology software. Your birth details stay in your own browser and are never stored on our servers.
