Frequently asked questions
Is this birth chart calculator really free?
Yes — calculate your full natal chart as many times as you want, no signup required for the chart itself. You get your Sun, Moon, Rising, all planetary placements, and a written interpretation, free.
What is the difference between a birth chart and a natal chart?
Nothing — they're two names for the same thing. A birth chart (or natal chart) is a map of where every planet was in the sky at the exact moment and place you were born. Some traditions also call it a horoscope chart or astrological chart.
How accurate is this birth chart calculator?
Very accurate. We use a deterministic astronomical ephemeris (Meeus / VSOP87) — a professional-grade calculation method accurate to within a fraction of a degree. The math is precise, but what it means for your life is yours to feel — your intuition is always your number-one guide.
Can I get a birth chart without my birth time?
Yes. Without a birth time, your Sun sign and your slower-moving planets are still accurate. Your birth time unlocks the rest: the Moon changes sign every couple of days, so without a time your Moon sign may be off, and your Rising sign and house placements can't be pinned down at all (check your birth certificate's long form or hospital records).
Can I get a birth chart without my birth location?
Yes, but with the same trade-off as missing a birth time — your Sun, Moon, and planets remain accurate, while Rising and houses become approximate. The closer to noon UTC you were born, the smaller the impact.
What is included in a birth chart with interpretation?
Our free birth chart calculator includes a written interpretation of your Sun (core self), Moon (inner world), and Rising (how you show up), plus a preview of your Venus love line in astrocartography. With an exact birth time it also names your Human Design type and how you're built to decide. Your Matrix Destiny core number, the rest of your Human Design chart, and your complete astrocartography map unlock with a Soul Coach account.
What is astrocartography and how does it relate to my birth chart?
Astrocartography takes your birth chart and projects each planet's energy onto a world map, showing you which cities activate your love life, career, abundance, or healing. It uses the same birth data as your natal chart. See our free astrocartography guide for details.
What is Human Design and how does it connect to astrology?
Human Design combines astrology, the I Ching, Kabbalah, and chakras into one body-graph. It uses your birth date, time, and location — exactly like a birth chart — but reads it as an energetic blueprint that tells you your Type, Strategy, and Authority. It's the perfect complement to your natal chart.
How is this different from CafeAstrology, Astro-Seek, or Astrodienst?
Those are excellent classical astrology calculators. Soul Coach uses the same astronomical math but layers in three additional systems — Human Design, Matrix Destiny, and Astrocartography — and writes a personalized daily reading on top of your chart. One blueprint, four wisdom systems, daily guidance.
Do you save my birth data?
Not on this page. The calculator runs your chart in the moment and doesn't store anything. If you create a Soul Coach account, your birth date, time, and location are stored privately so we can generate your daily readings — never sold, shared, or marketed.
