Birth Chart FAQ: Frequently Asked Questions
Common questions about reading and calculating your natal 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 place you were born. It shows where the Sun, Moon, and planets sat across the 12 zodiac signs and 12 houses, creating a unique astrological blueprint that astrologers use to interpret your personality, relationships, and life path.
What do I need to calculate my birth chart?
You need three pieces of information: your exact date of birth, your time of birth (as precise as possible, since it sets your Rising sign and house cusps), and your place of birth. With these, you can generate your full chart using our free birth chart calculator.
How do I read my birth chart?
Start with your 'Big Three' — your Sun sign (core identity), Moon sign (emotions), and Rising sign (outward style). Then look at each planet's sign to see how that energy is expressed, and each planet's house to see which area of life it focuses on. Reading these layers together builds a complete picture of your chart.
What is the difference between a planet's sign and its house?
A planet's sign describes how that energy expresses itself (its style and flavor), while its house describes where in your life that energy plays out (the life area it affects). For example, Venus in Leo shows a dramatic, generous way of loving, and Venus in the 7th house focuses that love energy on committed partnerships.
What are the Big Three in astrology?
The Big Three are your Sun, Moon, and Rising (Ascendant) signs. The Sun represents your core identity and ego, the Moon governs your emotions and inner world, and the Rising sign shapes how you come across to others. Together they form the foundation of any birth chart reading.
