Can You Buy Something That Doesn't Physically Exist? The Legal Status of Stars, Names, and Days
7 August 2026

Buying a star, naming something, or owning a day doesn't always mean what it seems to. We break down the difference between legal ownership, private registries, and symbolic title — and what you're really getting with Days Owners.
Can You Buy a Star?
Probably the best-known example.
For decades, companies have offered the chance to "buy" a star, give it a name, and receive a certificate confirming that name.
However, there's an important distinction between naming a star within a private registry and legally owning a star.
The International Astronomical Union (IAU), the body responsible for astronomical nomenclature, explicitly states that it does not offer commercial star-naming services and does not recognize names sold commercially by private companies.
In fact, the IAU explains that it distances itself from the commercial practice of "selling" fictitious star names.
That doesn't necessarily mean the commercial service is illegal.
It means something different:
the company isn't selling ownership of a star, nor an astronomical name officially recognized by the IAU.
What it's selling is a private service: registering a chosen name in its own system and providing the buyer with a certificate of that registration.
Some companies that sell these services state this explicitly in their own terms. Star Name Registry, for example, notes that the name is a gift or novelty item and carries no legal title or scientific recognition.
International Star Registry likewise clarifies that stars cannot be owned by an individual, and that its service allows a name to be symbolically associated with a star.
So What Is a Certificate Actually Worth?
Here's the interesting part.
A certificate doesn't need to prove you own a physical object to have meaning.
It can certify that a certain fact occurred:
- that a person made a purchase;
- that a name was registered;
- that a particular position was reserved;
- that a right of use was granted;
- that a person appears as the holder within a private registry;
- or that a particular contractual relationship exists.
So it's worth distinguishing between:
Legal ownership
The right recognized by law over a given asset.
Private registry
A system run by a company or organization that records certain rights, relationships, or assignments within its own system.
Certificate
The document that proves that entry or relationship.
A certificate can be perfectly authentic and valid as proof of a private registration, without that meaning the holder has legal ownership of the physical object it refers to.
The Moon Example
The phenomenon isn't limited to stars.
For years, companies have also offered "plots" of the Moon and other celestial bodies.
Here, international law provides an even clearer example.
The Outer Space Treaty establishes that outer space, the Moon, and other celestial bodies are not subject to national appropriation by claim of sovereignty, use, or occupation.
So a commercial certificate stating that someone "owns" a plot of the Moon is not equivalent to an internationally recognized real estate title.
The same distinction appears again:
the symbolic or contractual meaning of a registration is one thing; the legal ownership of what it represents is quite another.
So What Happens When We Buy Something Intangible?
In reality, we're surrounded by examples.
We buy: internet domains, software licenses, usernames, tickets, memberships, access rights, digital content, subscriptions, licenses, usage rights, certificates, experiences.
In many of these cases we don't receive a physical object.
What we acquire is a right or service defined by contractual terms.
European law specifically recognizes contracts related to digital content and services. EU Directive 2019/770 sets out specific rules for this type of contract and for consumer rights when the content or service isn't delivered properly.
So something being intangible doesn't make its purchase "unreal."
What matters is exactly what is being bought and what rights are promised to the buyer.
So What Do You Actually Buy on Days Owners?
This is the fundamental question.
When someone buys a day on Days Owners, they are not buying time itself, nor acquiring legal ownership of that day on the calendar.
The day will keep existing for everyone else.
What the buyer acquires is exclusive title within the Days Owners registry, tied to a specific date.
That title lets a person be publicly identified as the owner of that day on the platform, and to create, personalize, and maintain their page associated with that date, in accordance with the terms of service.
In other words:
You don't own the day. You own your unique place within Days Owners.
And that difference is exactly what makes the concept interesting.
What Does the Days Owners Certificate Actually Certify?
The Days Owners certificate exists to certify that:
[NAME] is the registered holder of [DATE] within the Days Owners system.
The certificate does not claim to replace a property title recognized by a public registry.
It is documentary proof of a title registered by Days Owners.
The company also maintains the registry of dates and their holders, so that the same date can never be assigned to two people simultaneously while the title is active.
That's why the certificate isn't just a keepsake.
It's the physical representation of a digital registration.
Is It Legal to Sell Something Like This?
The short answer is: yes, as long as what's offered to the consumer is clearly defined and doesn't lead them to believe they're acquiring a right that doesn't actually exist.
Consumer protection law requires precisely that, before entering into a contract, consumers receive clear, understandable, truthful, and sufficient information about a product or service's main features and its legal and economic terms.
This matters especially for conceptual or intangible products.
A company can sell an experience, a registration, a certification, or a contractual right.
What it shouldn't do is present that product as something legally different from what it actually is.
That's why Days Owners never claims that a buyer becomes the legal owner of time itself.
It claims something much more specific:
each date can have a single title-holder within the Days Owners universe.
The Difference Between "Ownership" and "Title"
The word "owner" can be confusing when we're talking about intangible concepts.
In everyday language we use "ownership" to describe many things that work very differently under the law.
We say: "My domain." "My profile." "My account." "My seat." "My license." "My spot."
In each case, the legal meaning can be different.
That's why, on Days Owners, the word Owner mainly represents an idea of exclusivity:
you are the only person occupying that position within the Days Owners registry.
The platform turns a universal date into a unique personal identity.
So Why Does a Certificate Exist at All?
Because certificates carry something that goes beyond strict legality.
They carry documentary, emotional, and symbolic value.
Someone might buy a day because they were born on it, met their partner on it, founded their company on it, achieved something important on it, lost someone on it, started a new chapter on it, want to celebrate an anniversary, want to use that date as part of their identity, or simply want their name linked to it.
The certificate turns that relationship into something tangible.
A date that anyone can check on a calendar becomes one with a name, a story, and an owner.
This Isn't the First Time We've Made Something Intangible Personal
Humanity has been doing something similar for a long time.
We name ships. We name buildings. We register domains. We create honorary titles. We name stars within certain private registries. We symbolically adopt animals. We buy experiences. We collect limited editions. And we keep certificates that document relationships that don't necessarily have a physical property behind them.
The value isn't always in physically owning something.
Sometimes it's in being the person associated with something unique.
Days Owners: Owning a Date That Represents Who You Are
That's the real idea behind Days Owners.
You can't buy a specific day on the calendar. No one can. It belongs to the calendar, to history, and to everyone who lives through it.
But you can get something no one else can hold at the same time:
being its one and only Owner on Days Owners.
You can put your name on it. Tell your story. Show who you are. Share your links. Present your project. Celebrate an important moment. And leave a lasting mark tied to a specific date.
Because in the end, Days Owners isn't really about buying a day.
It's about making a day speak for you.
So What About You? Which Day Would Be Yours?
Your birthday. The day you met someone. The day that changed your life. The day you started your company. The day you finally achieved what you'd been working toward for years. Or simply a date that's always felt special to you.
There are 366 days.
And each one can have only one Owner.
The question isn't whether you can buy time.
The question is:
