What is a natal chart?
A natal chart (or birth chart) is an astrological diagram that records the precise positions of the planets, Sun, and Moon at the moment of your birth. It is calculated based on three key parameters: date, time, and place of birth. A natal chart is your unique astrological “passport,” which does not repeat even among twins born minutes apart.
Each natal chart consists of 12 houses (areas of life), 10 planets (including the Sun and Moon as “luminaries”), zodiac signs, and aspects—the angular relationships between planets. Together, these elements form a complete portrait of your personality: character, talents, challenges, relationships, career inclinations, and life cycles.

After clicking the “Calculate” button, you will receive a graphical representation of your natal chart along with tables showing planetary positions, houses, and aspects.
What the calculation results show
The results include a complete natal chart with all key elements. The Sun in a zodiac sign reveals your core essence and life purpose. The Moon governs emotions, intuition, and inner world. Mercury determines thinking and communication style, Venus rules love and values, Mars governs energy and ambition. Outer planets (Jupiter, Saturn, Uranus, Neptune, Pluto) describe deeper life themes and generational influences.

Frequently asked questions about natal charts
Can I calculate a natal chart without an exact birth time?
Yes, but with limitations. If you don’t know your exact birth time, enter 12:00 (noon). In this case, planetary positions in signs will be correct, but house placements and the Ascendant will be inaccurate. For a full analysis, we recommend verifying the time on your birth certificate or through the civil registry archives.
What is the difference between a natal chart and a horoscope?
A horoscope is a generalized forecast for all people of the same zodiac sign, based solely on the Sun’s position. A natal chart is an individual map of a specific person, incorporating all 10 planets, 12 houses, and dozens of aspects. A natal chart is far more accurate and informative than a typical horoscope.
Does a natal chart change over time?
No, a natal chart is fixed permanently at the moment of birth. It reflects the “stellar imprint” of your personality. However, transits—the current planetary positions relative to your natal chart—constantly change and create different energetic influences throughout life.
What do the houses in a natal chart represent?
The 12 houses of a natal chart symbolize different life areas. The 1st house (Ascendant) represents appearance and self-expression. The 2nd house governs finances. The 3rd house—communication. The 4th house—family and home. The 5th house—creativity and romance. The 6th house—health and work. The 7th house—partnerships. The 8th house—transformations. The 9th house—travel and philosophy. The 10th house—career. The 11th house—friends. The 12th house—the subconscious and spirituality.
How can a natal chart help in daily life?
A natal chart helps you better understand yourself: your strengths and weaknesses, natural talents, relationship patterns, and career inclinations. It can indicate favorable periods for important decisions, help clarify complex relationships with others, and guide you toward your life path. Many people use their natal chart as a tool for self-awareness and personal development.
