Domain Age Checker
A domain age checker answers the question you actually have when you reach for one: how old is this domain? You rarely know the registration date already — that is the thing you are trying to find out. So this tool takes a domain name, looks the date up for you from the authoritative public registry, and reports the exact age in years, months, and days, plus the registrar, last-updated, and expiry dates where the registry publishes them.
It is free and needs no account or API key. The lookup uses RDAP, the modern replacement for WHOIS, which most registries expose over a public, browser-accessible endpoint. When a registry does not publish RDAP for its TLD, you can still type the date in manually, so you are never left at a dead end.
Enter a domain — the real registration date is read from the public RDAP (modern WHOIS) registry. Subdomains and full URLs are reduced to the registered domain automatically.
Enter the registration date manually instead
🌐 Note: this tool sends the domain name to the public RDAP / WHOIS registry to read its real registration date. No account or API key is needed, and nothing else is uploaded.
How to use the domain age checker
Type a domain and press Check age. The real registration date is fetched from the public registry and turned into an exact age and milestone read.
Just enter the domain – the date is looked up for you
Paste a domain, a subdomain, or even a full URL: the tool strips it down to the registered name (so www.blog.example.co.uk becomes example.co.uk) and queries RDAP, the registry-run successor to WHOIS. RDAP returns the original creation date as structured data, which the tool reads directly — no copying labels or trimming timestamps. The major generic TLDs such as .com, .net, and .org work instantly, and many country domains, including .uk, resolve too. The domain name is sent to the public registry to perform the lookup; nothing else leaves your browser.
Read the exact age, not a rounded year count
Most tools say a domain is fourteen years old. This one breaks the interval into years, months, and days and gives the total days, because the precise figure changes how a name is valued and renewed. The calculation uses UTC calendar maths, so it borrows days correctly across short months and leap years instead of assuming every month is thirty days. Alongside the age it surfaces the registrar and, where the registry publishes them, the last-updated and expiry dates, which together tell you whether a name is actively maintained or drifting toward a drop.
Treat the milestone flags as context, not a score
The tool marks when a domain crosses 5, 10, 15, and 20 years because those brackets are where aged-domain pricing tends to step up. A green tick means the threshold is passed, but it is a marker, not a verdict. A ten-year-old name that sat parked for eight of those years carries far less weight than a five-year-old name that published continuously and earned natural links. Use the milestone as a prompt to check the actual history, then judge value on the trajectory rather than the birthday.
Domain age checker frequently asked questions
Q1How does the tool find a domain’s registration date?
It queries RDAP, the registry-operated successor to WHOIS, which returns the original creation date as structured data. Most registries expose a public RDAP endpoint that a browser can read directly, so the tool fetches the date for the domain you enter and converts it into an exact age. No login or API key is required.
Q2Does it work for every domain and every TLD?
It works for the major generic TLDs such as .com, .net, and .org, and for many country-code domains including .uk. A few TLDs do not publish public RDAP, and premium or unregistered names return no record. When that happens the tool says so and lets you enter the registration date by hand, so you can still get the exact age.
Q3Is my lookup private?
To read a registration date the tool has to ask the registry, so the domain name you enter is sent to the public RDAP service. That is the same public data anyone can query, no account is involved, and nothing else you do is uploaded or stored. If you would rather not query the registry, use the manual date entry option instead.
Q4Does a domain’s age affect Google rankings?
Not directly. Google has said it treats domains as established after only a few months, so age itself is not a confirmed ranking factor. Age matters as a proxy: an older name has had more time to earn links and indexed content. That advantage only holds if the history is clean, with no spam era or expiry gap that reset its trust.
Q5Does domain age reset when a domain expires?
If a domain expires and is deleted, then registered by someone new, RDAP shows a fresh creation date and the age clock effectively restarts. If the original owner simply renews late within the grace period, the creation date is unchanged. This is why a dropped-and-recaught name can look young despite an older first registration.
