Birth Chart
Interpret the natal chart: planetary placements, house positions, aspects, and chart patterns.
Your birth chart -- also called the natal chart -- is a snapshot of the sky at the exact moment and place you were born. It maps every planet, angle, and significant point into a wheel of twelve houses, creating a symbolic portrait of your psychological makeup, relational style, vocational inclinations, and developmental trajectory.
Reading a birth chart is an act of translation. Each planetary placement tells part of the story: the Sun speaks to identity and creative vitality, the Moon to emotional needs and habitual responses, Mercury to how you process information, and so on through the outer planets, Chiron, Lilith, and the lunar nodes. The house a planet occupies shows the life arena where its energy is most active; the sign it falls in describes the style of that expression; and the aspects it forms to other planets reveal inner dialogues -- some harmonious, some charged with creative tension.
In this section you will find detailed guides to every planet in every sign and house, aspect interpretations, personality profiles based on Sun-Moon and Sun-Rising combinations, and articles on chart patterns like stelliums, T-squares, and grand trines. Use these resources as a comprehensive reference for natal interpretation, whether you are examining your own chart or preparing a reading for someone else.

Frequently Asked Questions
- What do I need to calculate my birth chart?
- You need three pieces of information: your date of birth, your exact time of birth (as close to the minute as possible), and your place of birth. The time determines the Ascendant and house cusps, which shift roughly one degree every four minutes. Without a precise birth time, the house placements and angles will be unreliable.
- Which part of the birth chart is the most important?
- No single factor outweighs everything else -- that is what makes chart reading an art. However, most astrologers begin with the "big three": the Sun sign, Moon sign, and Ascendant (Rising sign). Together they sketch your core identity, emotional temperament, and the persona you project into the world. From there, look at the chart ruler, any stelliums, and the most exact aspects.
- Can my birth chart change over time?
- The natal chart itself is fixed -- it records a single moment. What changes is how you relate to its symbolism as you mature. Transits, progressions, and other timing techniques describe the evolving conversation between the sky now and the sky at your birth, highlighting different natal potentials at different life stages.
