Calculate your baby's birth chart
Your baby's birth chart is the cosmic snapshot of its very first breath — the Sun, the Moon, the ascendant and all the planets exactly as they stood above its birthplace. Birth Codex calculates it for free with Swiss Ephemeris (NASA data) and interprets it with care: a lasting codex as a gift for a newborn.

What your baby's birth chart shows
Sun, Moon & ascendant — Your child's essential nature, its emotional needs and the way it meets the world.
Moon sign — What your baby needs to be soothed, to fall asleep and to feel safe — often the most useful line for new parents.
Human Design type — How your child naturally thrives: a loving orientation for supporting it the way it's meant to be.
Life path number & more — The overarching life theme, plus all 23 systems in a single reading.
Why an exact birth time is a gift with babies
With adults, the exact birth time is often unknown or imprecise — with a newborn it's recorded to the minute on the birth certificate. That is exactly what makes a baby's chart so precise.
The ascendant shifts by a whole sign roughly every two hours, and the house structure reacts sensitively to minutes. With your child's documented birth time, the ascendant and houses sit exactly right — a level of detail many adults can no longer reconstruct for their own chart.
The calculation itself relies on Swiss Ephemeris, the same astronomical ephemerides used in spaceflight. Astronomically exact, lovingly interpreted.
What parents see in the chart — and what they don't
A birth chart is not a prediction and fixes nothing about your child's life. It describes dispositions, temperament and needs — not a fate it's at the mercy of.
For parents that is exactly the value: a sensitive Moon baby needs something different from a spirited Mars child. The chart is an invitation to see and accompany your child, from the very start, the way it truly is.
How your child walks its path remains entirely up to it. The chart only hands it a map, not a script.
A codex as a gift for a newborn
A personal reading at birth is a gift that lasts — more beautiful and more lasting than any toy a child outgrows. Many families create the codex for everyone at once: for mum, for dad and for the newborn.
It becomes a little cosmic family portrait at the start of a life — something parents, grandparents and godparents love to give, and that you can pick up again together with your child years later.
Frequently asked questions
Can you calculate a birth chart for a newborn?✦
Yes. All you need is the date, time and place of birth. With babies the birth time is precisely recorded, which makes the chart especially accurate.
Do I need my baby's exact birth time?✦
For the ascendant and the houses, yes — and for newborns it's recorded to the minute on the birth certificate. Without a time we calculate Sun, Moon and planets, and the ascendant is estimated.
What sets Birth Codex apart?✦
Alongside the birth chart, Birth Codex calculates 22 more systems — Human Design, numerology, Gene Keys and more — all in one reading for your baby.
