What is a Birth Chart?

Imagine taking a photograph of the sky the exact moment you were born. A natal (birth) chart is exactly that—a two-dimensional map of where the planets, sun, and moon were located relative to Earth at your exact time, date, and place of birth.

A birth chart maps the planets onto this 360-degree zodiac wheel.

While your chart contains many complex elements like planetary aspects and astrological houses, the most important foundation is your "Big Three": your Sun, Moon, and Rising signs.

The Sun Sign: Your Core Identity ☀️

When someone asks "What's your sign?", they are asking for your Sun sign. It's the easiest to calculate because it only requires your birth month and day.

The Moon Sign: Your Emotional Compass 🌙

The Moon moves quickly, changing zodiac signs every 2.5 days. This is why you can be born on the same day as someone in a different year, but have completely different emotional temperaments.

The Rising Sign: Your Outward Mask ⬆️

Also known as the Ascendant, this is the zodiac sign that was rising over the eastern horizon at the exact minute of your birth. You must know your exact birth time to calculate this. Because the Earth rotates constantly, the rising sign changes every two hours.

Putting It All Together

If your personality was a house: Your Sun is the foundation and structure. Your Moon is the private bedroom where you keep your secrets. Your Rising sign is the front door, the landscaping, and the exterior paint color.
