Find out exactly how old a website's domain is: the date it was first registered, its age in years, months and days, when it expires and which registrar holds it. Paste up to 50 domains at once to compare them in a sortable table.
Last updated:
Enter one or more domains and click Check domain age to see when each was registered, how old it is and when it expires.

How to use the Domain Age Checker
Enter one or more domains, one per line or separated by commas. Full URLs such as https://www.example.com/page work too.
Click Check domain age or press Enter.
Read the age: for one domain you get the exact age, registration date, expiry date, registrar and a timeline.
Compare in bulk: with several domains, sort the table by age, days left or registrar and see the oldest and newest at a glance.
Export the results as CSV or copy them into a spreadsheet, or copy a link to share the check.
Where the dates come from
Every domain extension is run by a registry that keeps the official record of each name. The checker asks that registry through RDAP (Registration Data Access Protocol), the structured, HTTPS-based successor to WHOIS, and reads three events from the record:
RDAP event
Shown as
What it means
registration
Created
When the current registration was first created. Domain age is counted from this date.
expiration
Expires
The end of the paid registration period. Most domains auto-renew, which moves this date forward by a year or more.
last changed
Last updated
The last time the record changed, for example a renewal, a new name server or a registrar transfer.
The age is a calendar difference: from March 15, 1985 to today it counts full years first, then full months, then the remaining days, the same way you would calculate a person's age. The day count is the exact number of days between the two dates in UTC.
Domain lifecycle after expiry
An expiry date in the past does not always mean the name is free. For most generic extensions such as .com, .net and .org the typical sequence is:
Stage
Typical length
Can the owner keep it?
Auto-renew grace period
Up to 45 days after expiry (registrar policies vary)
Yes, by renewing at the normal price
Redemption period
30 days
Yes, usually with a restore fee
Pending delete
5 days
No; the name is then released and its age starts again when re-registered
Tips for using domain age
Vetting a shop or sender: a domain registered a few days ago that claims to be a long-established brand is a common sign of a scam site or phishing email.
Buying an expired or used domain: check the age and the last-updated date, and look at archived snapshots to see how the name was used before.
Managing a portfolio: paste all your domains, sort by Days left and renew anything flagged as expiring within 60 days.
Frequently asked questions
How is domain age calculated?
Domain age is the time from the domain's creation (registration) date in the registry to today. The checker reads the registration event from the registry's RDAP record and counts whole calendar years, months and days, plus the total number of days. Decimal years use the average Gregorian year of 365.2425 days.
Does domain age affect SEO?
Google has said that domain age by itself is not a ranking factor. Older domains often rank well because they have had more time to earn links, content and trust, not because of the date itself. Domain age is still useful when judging whether a site, seller or email sender is established or brand new.
Why does the age reset after a domain expires?
If a domain is not renewed, it is eventually deleted and released. When someone registers it again, the registry creates a new record with a new creation date, so the age starts from zero. A domain that changes owners through a transfer or sale keeps its original creation date.
Why can't some domains be checked?
Some country-code extensions do not offer a public RDAP service, and some registries limit how many lookups you can make in a short time. Unregistered domains return not found. For extensions without RDAP, use the registry's own WHOIS website.
Is the website age the same as the domain age?
Not always. A domain can be registered years before a website is launched on it, or a site can move to a newer domain. The registration date tells you when the name was first registered by its current lineage of owners. To estimate when content first appeared, look at archived snapshots on a web archive service.
What is the difference between this and a WHOIS lookup?
A WHOIS lookup shows the full registration record for one domain, including contacts, status codes and name servers. The domain age checker focuses on dates: it computes the exact age and days until expiry, and it can compare up to 50 domains in one sortable table.
Are my lookups private?
The lookups go directly from your browser to rdap.org, which redirects to the official registry RDAP server for each extension. FreeToolCabin does not receive or store the domains you check.
Are all the tools on FreeToolCabin tested for quality and accuracy?
Yes! Every tool on our site undergoes automated Q/A testing in real browser environments to ensure high precision, correct output, and zero errors. If you happen to spot a bug or have a suggestion, please contact us at [email protected] and our team will review it right away.
