The astral chart, or natal chart, is a graphic depiction of the sky at the exact moment of your birth. It places the ten celestial bodies used in Western astrology within the twelve signs of the zodiac and the twelve astrological houses. This tool automatically computes the planetary positions, the ascendant, and the midheaven from your date, time, and place of birth. Drawn from a tradition more than two millennia old, the natal chart remains the reference document for any serious astrological analysis, whether approached symbolically, psychologically, or culturally.
An astral chart, also called a natal chart or birth horoscope, is a flat projection of the celestial vault as it appeared from your place of birth at the exact moment you came into the world. It includes ten celestial bodies (Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto), spread across the twelve signs of the tropical zodiac and the twelve astrological houses. Its codification traces back to Claudius Ptolemy, whose Tetrabiblos, written around 150 CE, remains the foundational work. The Babylonians, as early as the 2nd millennium BCE, had already laid the groundwork for this systematic observation of the sky.
To compute an accurate astral chart, three pieces of data are essential: your date of birth, your time of birth (as exact as possible, ideally to the minute), and your place of birth (city or geographic coordinates). The time governs the calculation of the ascendant and the houses, which change roughly every two hours. The place provides the latitude and longitude needed for house division. In many countries, the time recorded on the official birth certificate is the most reliable source. Our tool applies the Placidus house system, the most widespread in Western astrology, and the tropical zodiac.
Start by identifying your core trio: Sun (identity), Moon (inner life), and ascendant (social appearance). Then spot any planetary clusters in a sign or house, a sign of a central life theme. Note the major aspects: conjunctions, oppositions, squares, trines, and sextiles. Avoid reading the chart piecemeal, sign by sign: a natal chart is interpreted as a coherent whole, where each element softens or reinforces the others. Astrology is a symbolic and cultural framework, not a validated predictive science.
Yes, for a complete astral chart. Without a precise time, you can still know the position of the Sun and the slow planets, but the ascendant, midheaven, and house distribution cannot be calculated. These elements are central to the interpretation.
The sun sign only points to the position of the Sun at your birth, that is one-twelfth of the astrological picture. The astral chart includes the ten celestial bodies, the twelve houses, and their mutual aspects, offering a far more nuanced portrait than mere zodiac membership.
You can request a full copy of your birth certificate from your local registry, where the time is recorded. Otherwise, some astrologers use chart rectification, a method that adjusts the presumed time based on major life events.
No, the natal chart is fixed: it reflects the sky of a single instant. However, astrologers study transits and progressions, which compare the current or symbolic positions of the planets to your birth chart for a dynamic reading.
