A natal chart calculation is a special astrology chart that shows how the sky looked at the time and place of a person’s birth. This map shows in detail the positions of the planets, sun, moon and other astrological elements at that moment. Birth chart calculation is used as a method that gives insight into an individual’s life, character and future.
The following information is required to calculate the birth chart:
- Date of birth (day, month, year)
- Time of birth (hours and minutes)
- Place of birth (city and country)
Using this information, astrologers calculate the positions of the planets and other celestial bodies and display this information on a map. This map contains clues to different areas of a person’s life (love, career, health, etc.).
Birth chart calculation usually involves the following steps:
- Collection of Birth Information: The date, time and place of birth indicated above are collected.
- Calculation of Planetary Positions: Using this information, the positions of the planets, the sun and the moon at the time of birth are calculated.
- Identifying the Houses: There are 12 houses in the birth chart, each representing a different area of life. Your birth time determines the position of these houses.
- Placement of Signs and Planets: In line with the calculated information, it is determined which sign or planet is in which house.
- Interpretation: An expert astrologer interprets this chart and provides information about the person’s character, career, love life and future.
Some online tools and applications allow users to calculate their own birth charts for free. However, for a more in-depth analysis and personalized interpretation, it is usually preferable to consult an astrologer.
Birth chart calculation is a valuable tool for people interested in astrology to learn more about themselves and others.

Calculating the Positions of the Planets
The methods used to calculate the positions of the planets at the time of birth are quite complex and are usually done using astronomical tables and computer software. However, for a basic understanding, the following steps are followed:
- Efemeris Usage: Ephemeris is a table containing the celestial coordinates of the sun, moon and planets for a given date and time. Astrologers use the date of birth to find out which sign the planets are in from these tables.
- Calculating Ascendant Sign and Houses: The rising sign is the sign on the eastern horizon at the time of birth and represents the first house of the birth chart. Using the time and place of birth, the rising sign and the boundaries of the 12 astrological houses are calculated.
- Determination of Planetary Positions: Using ephemeris tables and ascendant sign information, the planets’ signs at the time of birth and in which house they are located are determined.
- Angles and Directions: The angles between the planets are also calculated. For example, if there is a 90-degree angle between two planets, this is called a “square” aspect and usually indicates a challenging influence.
- Degrees The degree of each planet in its sign is also important. These degrees show the positions and effects of the planets in that sign in more detail.
- Nakshatra and Asteroids: Some astrologers add not only the positions of the planets, but also certain star groups (Naqshatra) and asteroids to the chart.
These calculations and analyzes are usually done by astrology software and expert astrologers. These software programs perform mathematical and astronomical calculations automatically, providing accurate and fast results. However, for a basic understanding, it is useful to know the steps mentioned above.

Identification of Houses
Identifying the houses in the birth chart is an important step that sheds light on different areas of an individual’s life. The 12 houses in the natal chart represent different aspects of life and the planets in these houses help us understand the experiences and interactions in that area.
Steps in Identifying Houses:
- Calculating the Ascendant: The first step is to determine the rising sign. The ascendant is the sign on the eastern horizon at the time of birth and represents the first house of the birth chart. The time and place of birth are critical for determining the rising sign.
- Determining the Boundaries of the Houses: Starting from the Ascendant, the zodiac circle is divided into 12 equal parts, each part representing a house. In classical western astrology, the Placidus house system is usually used, but other systems exist.
- Meanings of Houses:
- 1st House: Represents personality, physical appearance, basic traits of character.
- 2nd House: Represents material values, finances and self-esteem.
- 3rd House: It represents communication, siblings, close environment and short travels.
- 4th House: It is about family, roots, home and the inner world.
- 5th House: Represents creativity, love life, children and fun.
- 6th House: It represents daily routines, health and work life.
- 7th House: It is about marriage, partnerships and legal matters.
- 8th House: Transformation, death, inheritance and sexuality.
- 9th House: It is related to philosophy, higher education, distant travel and spirituality.
- 10th House: It is about career, public standing and authority figures.
- 11th House: It is about friendships, groups, social life and ideals.
- 12th House: It is related to the subconscious, spirituality, hidden enemies and solitude.
- Placement of Planets in Houses: Determining which house the planets are in helps us understand how that planet will affect the area of life represented by that house.
Correctly identifying and interpreting the houses is critical to better understand the different dynamics and potential opportunities or challenges in an individual’s life. For this reason, determining the houses in the birth chart calculation process should be done with care.

Placement of Signs and Houses in Birth Chart Preparation
The placement of signs and planets in the birth chart calculation process is important to understand the innate characteristics of the individual and the potential interactions in their life.
Placement of the Zodiac Signs and Planets:
- Use of Ephemeris: Astrologers use ephemeris tables for the date of birth to determine which sign the sun, moon and other planets are in on that date.
- Placement of the Planets in the Signs: With the information obtained from the ephemeris chart, the sign in which the planets are located is determined and placed in the birth chart. For example, if the Sun is in Leo at the time of birth, the person has Leo characteristics.
- Degrees The degree of the planets in that sign is also determined. This degree shows in more detail the strength of the influence of the planet in that sign and its characteristics.
- Moon Nodes The natal chart also includes the North and South Nodes of the Moon. These express fatalistic aspects and spiritual purpose.
- Placement of Planets in Houses: Planets are placed in the previously calculated houses based on which house they are in. For example, Mars in the 3rd house indicates that the person’s communication style can be energetic and combative.
- Angles The angles between the planets (conjunction, square, triangle, etc.) are also calculated and added to the chart. These angles show the interaction and harmony of the planets with each other.
- Asteroids and Other Celestial Bodies: Some astrologers add asteroids such as Ceres, Juno, Pallas, Vesta and wounded healing energies such as Chiron to the chart.
- Interpretation: Putting all this information together, the astrologer interprets the person’s birth chart. The combinations of planets and signs give information about the person’s characteristics, abilities, difficulties and potentials.
The signs and planets in the birth chart are a guide to understanding the inner world and life journey of the individual. Therefore, the correct placement and interpretation of the signs and planets in the birth chart calculation is of great importance.

Interpreting the Birth Chart
Birth chart interpretation is an essential tool of astrology to understand the various potentials, challenges and tendencies in an individual’s life. Here are the basic steps on how to interpret a birth chart:
- Examining the Ascendant: Before starting interpretation, it is important to examine the ascendant sign in the birth chart. The ascendant sign shows how a person interacts with the outside world and makes a first impression.
- The Sun, Moon and Ascendant Trine: The Sun sign represents character and ego, the Moon sign represents emotional reactions and the inner world, and the rising sign represents the outward personality. When analyzed together, this triad gives information about the general structure of the individual.
- Placement of the Planets in the Zodiac Signs: The sign in which each planet is located shows how the energy of that planet is expressed. For example, Mars in Aries shows that a person can be energetic and entrepreneurial.
- Planets in Houses: The house in which the planets are located indicates in which area of life the energy of that planet is more effective.
- Angles between the Planets: Aspects between the planets (conjunction, square, triangle, opposition, etc.) express the harmony and interaction of the planets with each other. For example, a favorable aspect between the Sun and the Moon can be interpreted as a sign of emotional balance.
- Identifying Dominant Planets and Signs: The dominant planet and sign in the chart show the basic characteristics of the person and which energies are more dominant.
- Examining the Houses: The houses in the chart represent different areas of life, and the planets in these houses indicate what experiences will be had in these areas.
- Special Placements and Stars: Fixed stars, asteroids, and other special placements are also analyzed to help interpret the chart in more detail.
- Periodic Analyses: Transits, progressed charts and periodic analyses can be used to examine specific periods and influences in a person’s life.
- Holistic Approach: In interpretation, all these factors are brought together to understand the innate potential of the individual and the possible interactions in his/her life.
Interpreting a birth chart is a process that requires both technical knowledge and intuitive ability. An experienced astrologer can bring all these components together to provide a detailed and comprehensive analysis of an individual’s life.
