What is a Natal Chart?

A natal chart is an astrological chart built for the moment of a person's birth. It displays the positions of the Sun, Moon, and planets in zodiac signs, their placement in houses, and angular relationships (aspects) between them. The natal chart is considered the primary tool of astrology for analyzing character, talents, and life path.

How to Calculate a Natal Chart?

To calculate a natal chart, three parameters are needed: date of birth, exact time, and place. Our calculator uses Swiss Ephemeris — a professional astronomical library with arcsecond precision. All computations run directly in your browser via WebAssembly technology.

Planets in Zodiac Signs

Each planet in the natal chart has its meaning: the Sun — core personality and will, the Moon — emotions and subconscious, Mercury — thinking and communication, Venus — love and values, Mars — energy and action. The zodiac sign a planet occupies determines how its energy manifests.

Houses and Aspects

The 12 astrological houses represent different life areas — from personality (1st house) to spirituality (12th house). Aspects between planets show how different parts of your nature interact: harmonious aspects (trine, sextile) ease things, while tense ones (square, opposition) create challenges for growth.

Frequently Asked Questions about Natal Charts

What is a natal chart?
A natal chart (birth horoscope) is a map of the sky at the moment of your birth. It shows the positions of the Sun, Moon, and planets in zodiac signs and houses, as well as aspects between them.
Is exact birth time needed?
For a complete chart with houses and Ascendant, exact time is needed. Without it, a cosmogram can be built — planet positions in signs and aspects will be accurate, but houses won't be calculated.
How accurate are the calculations?
We use Swiss Ephemeris — the most accurate astronomical library with arcsecond precision. It's the same engine used by professional software (ZET, Solar Fire).
What do houses mean in a natal chart?
The 12 houses represent different life areas: 1st — personality, 4th — family, 7th — partnership, 10th — career, etc. Planets in houses show where their energy manifests.
What are aspects between planets?
Aspects are angular relationships between planets. Trine (120°) and sextile (60°) indicate harmony, square (90°) and opposition (180°) — tension and challenges, conjunction (0°) — merging of energies.
