What Is a Birth Chart?

A birth chart (also called a natal chart) is a map of the sky at the exact moment you were born. It shows where the Sun, Moon, and planets were positioned across the twelve zodiac signs and twelve astrological houses. Read our complete beginner's guide to birth charts.

What This Calculator Shows

• Sun Sign — Your core identity, calculated using precise astronomical algorithms.
• Moon Sign (approximate) — Your emotional inner world. The exact Moon sign requires your birth time.
• Life Path Number — Your numerological core purpose.
• Chinese Zodiac Animal — Your Chinese astrology animal based on your birth year.

The Big Three in Astrology

Your Sun, Moon, and Rising sign form your "Big Three" — the foundation of your astrological identity. While this calculator gives you two of the three, the full SoulChart app calculates all three plus every planet, house, and aspect in your chart.

Why Birth Time Matters

Your exact birth time determines your Rising sign (Ascendant), house placements, and precise Moon position. Without it, we can still calculate your Sun sign and Life Path number accurately, but the Moon sign shown here is approximate.
