Question 1

What is a birth chart?

Accepted Answer

A birth chart (also called a natal chart) is a map of where the Sun, Moon, and planets were positioned in the sky at the exact moment and place you were born. It is divided into 12 houses, each corresponding to a different area of life. Your birth chart is unique to you and is the foundation of astrological interpretation.

Question 2

What does a birth chart include?

Accepted Answer

A birth chart includes the positions of 10 celestial bodies — Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto — each placed in a zodiac sign and a house. It also shows your Ascendant (rising sign) and Midheaven, which mark the eastern horizon and the top of the sky at your birth moment.

Question 3

Do I need my birth time for a birth chart?

Accepted Answer

Your birth time is needed to calculate your rising sign (Ascendant), Midheaven, and house placements — which change every two hours as Earth rotates. Without a birth time you can still see your Sun, Moon, and planetary sign placements, but your chart will be incomplete. If you don't know your birth time, check your birth certificate or contact the hospital where you were born.

Question 4

What is the whole sign house system?

Accepted Answer

The whole sign house system is the oldest known house system in Western astrology, originating with Hellenistic astrologers in antiquity. Each of the 12 houses corresponds exactly to one complete zodiac sign, beginning with the sign of the Ascendant as the first house. Many modern astrologers prefer it for its clarity and historical depth.

Question 5

What is the difference between a birth chart and a Sun sign?

Accepted Answer

Your Sun sign is just one placement in your birth chart — the zodiac sign the Sun was in on your birthday. A full birth chart includes all 10 planets, your rising sign, Midheaven, and 12 houses, giving a far more complete and personal picture than your Sun sign alone.
