Question 1

What is a natal chart?

Accepted Answer

A natal chart — also called a birth chart — is a diagram of the sky as it appeared at the exact moment and location of your birth. It records the positions of the Sun, Moon, and planets against the backdrop of the zodiac and distributes them across twelve houses that correspond to different areas of life. Western astrologers read the chart by interpreting each planet's sign placement, its house position, and the angular relationships (aspects) it forms with other planets. Because the sky changes continuously, every person born at a different moment or place has a distinct chart, even within the same family.

Question 2

What does a Western natal chart include?

Accepted Answer

A Western natal chart includes: the Sun sign (the zodiac sign the Sun occupied at birth, often associated with identity and core drive); the Moon sign (the sign the Moon occupied, associated with emotional patterns and instincts); the Rising sign or Ascendant (the zodiac sign rising on the eastern horizon at birth, often read as the outward manner or first impression); the placements of all visible planets — Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto — each in a sign and house; the twelve houses (each governs a domain such as self, resources, communication, home, creativity, health, relationships, shared resources, philosophy, career, community, and the inner life); and the aspects — angular distances between planets — which describe how the planetary energies interact. Common aspects include the conjunction (0°), sextile (60°), square (90°), trine (120°), and opposition (180°).

Question 3

How accurate is a natal chart, and does birth time matter?

Accepted Answer

The accuracy of a natal chart depends directly on the accuracy of the birth details you provide. The Sun and most outer planets move slowly enough that the date alone places them reliably. The Moon moves roughly one degree every two hours, so an incorrect birth time can shift the Moon into a different sign. The Rising sign (Ascendant) completes a full cycle in roughly 24 hours — it changes sign approximately every two hours — so birth time is essential for an accurate Rising. The house cusps depend entirely on both time and place. Zodiacs uses your birth date, birth time, and birthplace to calculate all placements; if you do not know your exact birth time, the Sun and Moon positions are still calculated, but the Rising sign and house placements may be approximate or omitted.

Question 4

What can I use my natal chart for?

Accepted Answer

A natal chart is a tool for self-reflection, not a script. People use it in a range of practical ways: understanding emotional needs the Moon sign suggests, noticing communication patterns linked to Mercury, seeing relationship dynamics described in the seventh house, and identifying the areas of life where a planet's influence is concentrated.

Chart timing — tracking live transits as they contact your natal planets — can help with decision pacing: when to push a project forward, when to wait, when a period of friction is likely to pass. Zodiacs reads these transits daily against your chart, alongside the BaZi day cycle, so the signals from multiple traditions either reinforce or qualify each other.

Compatibility readings layer two natal charts together — the seventh house, Venus, and Mars placements in both charts describe where a pair sits easily and where it pulls against itself. Zodiacs also calculates Sun-sign compatibility as a starting point if you don't have a full chart yet.
