Domain Age Checker

Domain age is the time since a registration date recorded at a registry. Expiry is when the current registration period ends. Official dates come from WHOIS or the registry. This card displays those fields without that lookup.

Run it twice on the same domain and the year can change. That is the fastest way to see the card is not a WHOIS result. Use a registrar or a real WHOIS record when age is part of a purchase or a spam decision.

Created year is one of the values Domain Age Checker puts on screen. A registration date is the day the registry recorded the name. The sample picks 2010 plus a random 0 to 9, then prints 15 October of that year. The year can change on the next click. It is not the domain’s birthday.

Read Age in years on its own before you mix it with the other rows. Age is the gap between the created year and the current year. The card subtracts the random year from this year. Because the year is random, the age is random too.

Age in days answers a narrower question than the headline number. Some reports also show a day count. Days are years times 365 plus a random 0 to 99. Leap days are ignored and the extra 0 to 99 is noise, not a registry day count.

Treat Updated date as a label with a specific job. Updated is the last change the registry recorded. The sample always uses 20 January of the current year. That January date does not mean the domain was modified in January.

The Expiry date line is worth a full stop. Expiry is the end of the current term. The sample uses 15 October two years from now. Do not renew from this October date. It is not the registrar’s date.

The hostname is cleaned if you paste a URL, and that cleaned name is printed on the card. Printing the name is not a registry lookup. Updated is always 20 January of the current year, and expiry is always 15 October two years out.

If you remember one sequence from Domain Age Checker, remember the fields in the order they change a decision. Created year matters because A registration date is the day the registry recorded the name. In practice, The sample picks 2010 plus a random 0 to 9, then prints 15 October of that year. The mistake to avoid is this: The year can change on the next click. It is not the domain’s birthday. Age in years matters because Age is the gap between the created year and the current year. In practice, The card subtracts the random year from this year. The mistake to avoid is this: Because the year is random, the age is random too. Age in days matters because Some reports also show a day count. In practice, Days are years times 365 plus a random 0 to 99. The mistake to avoid is this: Leap days are ignored and the extra 0 to 99 is noise, not a registry day count. Updated date matters because Updated is the last change the registry recorded. In practice, The sample always uses 20 January of the current year. The mistake to avoid is this: That January date does not mean the domain was modified in January. Expiry date matters because Expiry is the end of the current term. In practice, The sample uses 15 October two years from now. The mistake to avoid is this: Do not renew from this October date. It is not the registrar’s date. After that, the checks are simple. You ran the check twice and watched the year. You did not quote a 2010–2019 created date as fact. You did not treat 15 October as the real expiry. You ignored the day-count extra random number. A WHOIS client is the source for any age you publish.

Keep Domain Age Checker as this step only. When the job moves on, the WHOIS Lookup is the next page: WHOIS Lookup takes a domain and shows registrar, registered date, expiry, registrant, status, and nameservers. The Domain Expiry Checker covers a different piece of the same work: Domain Expiry Checker takes a domain and shows days remaining, an expiry date, a creation date, and a registrar.
