What your birth chart shows
Your Sun sign is your core drive — the self you're growing into. Your Moon sign is your inner weather: how you feel, soothe, and react before you think. Your Rising sign (ascendant) is the lens you meet the world through and the way others first read you. Around them, the planets fall into twelve houses — the arenas of life where each energy plays out.
From a chart to a change
A chart is a beautiful snapshot — but a snapshot doesn't move you. Cosmuna reads your chart as one half of your Blueprint (the cosmic vibration you were born under) and pairs it with your inner vibration— your patterns, your aim, the self-image you're shifting. Cosmo, your companion, remembers all of it and helps you take the next real step, at the right time. The chart is the door; the becoming is the room.
Frequently asked
What is a birth chart?
A birth chart (or natal chart) is a map of the sky at the exact moment and place you were born — the positions of the Sun, Moon, planets, and the rising sign across the twelve houses. It's the starting point for understanding your nature and timing.
Do I need my exact birth time?
Your Sun and most planetary signs are accurate without a birth time. Your Rising sign and house placements need an accurate time — if you don't know it, you can still generate a meaningful chart and add the time later.
Is this birth chart calculator free?
Yes. Your chart is free and no account is required to see it. Creating an account lets Cosmo, your companion, read your full Blueprint over time and help you act on it.
How accurate is it?
Positions are computed with the Swiss Ephemeris — the same high-precision engine used by professional astrologers — so your chart matches what Cosmo uses inside the app.
