Discover Your Birth Chart

What Is a Birth Chart?

A birth chart, also called a natal chart, is a map of where the Sun, the Moon and the planets were at the exact moment and place you were born. Your Sun sign is only one piece of it. The full chart also shows your Moon sign, your rising sign (Ascendant) and the zodiac sign of every planet, which is why two people born under the same Sun sign can feel so different.

This calculator uses real astronomical data from AstrologyAPI.com and the tropical zodiac, the system used by most Western astrologers.

What You Need

• Date of birth.
• Time of birth, as exact as possible. It is usually written on your birth certificate. The time matters most for the Moon and the Ascendant: the Moon changes sign roughly every two and a half days, and the rising sign changes about every two hours.
• Place of birth. Type the city and pick it from the search results so the latitude, longitude and time zone are filled in correctly.

Don’t know your birth time? You can still calculate your chart, but treat the Ascendant, the Moon (if it was near the edge of a sign) and the house positions as approximate.

How to Read Your Results

The Big Three

• Sun sign — your core identity and what gives you energy.
• Moon sign — your emotional needs and what makes you feel safe.
• Rising sign (Ascendant) — the first impression you give and how you approach new situations.

The Planets

Each planet represents a part of life, and its sign describes the style in which you express it. Mercury shows how you think and communicate, Venus how you love and what you value, Mars how you act and assert yourself, Jupiter where you grow, and Saturn where you learn discipline. The slower outer planets — Uranus, Neptune and Pluto — describe generational themes as much as personal ones.

The Houses

The twelve houses divide the chart into areas of life, such as relationships (7th house), career (10th house) or home (4th house). A planet’s house shows where its energy tends to show up most.
