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.
