The hidden story of the week above our heads
Before Sunday was just Sunday. Before Monday meant back to school. Before Friday meant the weekend was almost here, people looked up. They watched seven bright wanderers move across the stars. From those wanderers came the names of the days we still use today.
A children’s book about a child, the adult who loves them, and the ancient sky-story hidden inside every ordinary week.
The Core Idea
Long before modern astronomy, people used the word “planet” differently.
A planet was a wanderer — something that moved against the background of the fixed stars. Ancient sky-watchers saw seven of these wanderers:
Those seven wanderers became linked to the seven days of the week. And the pattern held.
Seven days.
Seven wanderers.
A week written in the sky.
The Book
Seven Days, Seven Wanderers follows a curious child and the adult who loves them as they explore where the days of the week came from.
The story moves at the pace of a bedtime conversation — warm, curious, unhurried. One day per chapter. One wanderer per day. One discovery at a time.
A few of the days
Moon's day
The Moon moved through the night sky. Ancient sky-watchers gave it a day.
Mars's day
Mars wandered through the stars, bright and red. A warrior's planet. A warrior's day.
Venus's day
The brightest wanderer before sunrise. Beautiful enough to name the last day before rest.
How the Book Works
A short read-aloud story moment between the child and the adult who loves them — warm, curious, unhurried.
A warm, painterly illustration of the child, the adult, and the wanderer connected to that day.
A single word from Spanish, French, Italian, or Portuguese that reveals how language remembers — or reshapes — the story.
One clear, beautiful insight. Each spread leaves children with a real piece of knowledge — not a fact to memorize, but a story to carry.
Monday is the Moon’s day.
The Moon was once counted as a planet because it wandered through the night sky. It moved. It changed shape. It ruled the dark. Ancient sky-watchers decided it deserved a day.
And the name still carries that memory — in ways you’ll discover when you read the book.
Why It Matters
Asks children to memorize.
Invites them to notice.
Every name in every language carries the history of the people who spoke it. Most of us walk past that history every day without noticing.
They inherited the same sky and decided differently what to remember, what to rename, and what to replace. None of them were wrong.
A child who asks that question about a word will eventually ask it about everything. That question is the most important education there is.
The goal is not just to teach the days of the week.
The goal is to help children feel the thrill of asking:
“Where did that come from?”
That question can last a lifetime.
Who It Is For
Children learning the days of the week and beginning to notice words, sounds, patterns, and the sky.
Families who want a read-aloud book that feels warm, beautiful, and genuinely interesting for both generations.
Educators looking for a simple bridge between literacy, astronomy, mythology, etymology, cultural history, and multilingual exposure.
Science centers and gift shops that want a story-driven way to connect children to the sky — and to the words we still use to describe it.

Hidden in plain sight
Spanish, French, and Italian kept the planetary names visible — you can still see them if you know where to look. English disguised them through Norse mythology. Portuguese replaced them entirely through religious tradition. Same sky. Three different stories about what happened to the names.

When Germanic tribes adopted the Roman seven-day week, they kept the planetary structure but replaced four of the Roman gods with their own Norse equivalents — gods they considered a match.
Sunday, Monday, and Saturday came directly from the Latin — Sun’s day, Moon’s day, Saturn’s day — and were not replaced.
English kept the planetary structure.
It just renamed the gods.
Like English, German kept the Norse names for Thursday and Friday — Donnerstag(Donner, Thor’s thunder) and Freitag(Freya’s day). But for Wednesday, German did something no other major European language did.
German dropped both the Roman god (Mercury) and the Norse god (Woden) entirely. No mythology. No planet. Just a practical description of where Wednesday falls in the week. The wanderer is gone.
Some languages disguised the planet.
German erased it.
Instead of preserving most of the planetary names, Segunda-feira, Terça-feira, Quarta-feira, Quinta-feira, and Sexta-feira reflect a later religious and cultural reshaping of the week.
Names do not just come from the sky.
They also travel through people, cultures, and time.

The Series
Seven Days, Seven Wanderers is the first title in a multilingual series. Each edition is written natively in its own language — not translated, but authored from that language’s own vantage point on the sky.
Every edition includes a cross-language addendum: a window into how other languages carried, disguised, or deliberately replaced the same planetary names. The story is the same sky. The entry point changes with every language.
The longer vision: a platform where any family can generate this book in their language, with characters that look like them, in a visual style from their world. The etymology stays true. The story belongs to whoever is reading it.
Your language
Swahili, Arabic, Japanese, Portuguese — whichever language the child grows up inside.
Your characters
A grandmother, a mother, an uncle, a father. Whoever that adult is in the child's life.
Your world
The setting, the art style, the cultural detail. The sky is universal. The story is yours.
What if every child could find
their own sky in the same story?
Planned editions
More languages to follow. Each edition authored natively, not translated.
Same sky. Every language its own entry point.
In Development
The book is in development. The platform is being designed. Leave your email and we’ll share progress as it happens — no noise, just the moments worth sharing.
