Your sky at birth
Birth chart
The complete map of the heavens at your first breath — planets, signs, houses, and aspects calculated to professional ephemeris standard.
A birth chart (natal chart) freezes the sky at your moment of birth. It is the foundation for every serious reading — not a Sun-sign horoscope, but the full pattern of temperament, drive, relationship style, and life direction. An astrology birth chart uses the same map; the words are interchangeable.
The main pieces
- Planets — psychological functions (identity, emotion, communication, desire, drive, and more).
- Signs — how each function expresses (style, tone, motivation).
- Houses — life areas where themes show up (home, partnership, career, etc.).
- Aspects — geometric relationships between planets — harmony, tension, or blend.
- Angles — Ascendant and Midheaven anchor the chart to your birth location.

What you need to calculate yours
Date of birth, time of birth (as accurate as possible), and birthplace. Time matters: it sets the Ascendant and house cusps. Without it, house-based readings and the rising sign are unreliable.
What a complete birth chart includes
- Planets — psychological functions from identity to transformation.
- Signs & houses — how and where each theme shows up in life.
- Aspects — dialogue between parts of your personality.
- Angles — Ascendant (rising) and Midheaven anchor the chart to Earth.
