About Our Domain Age Checker

Learn how The Domain Age checks registration age using public RDAP records, calculates domain age, and handles missing dates, cached results, and registry limits.

Start with the record

We look up a domain’s registry using IANA’s RDAP service directory and request its public registration record over HTTPS. The creation date is the starting point for our age calculation. We also show expiration dates, registrar details, nameservers, registration statuses, and DNSSEC information when provided.

Understand the limits

A registration date is not a website launch date, a guarantee of trustworthiness, or a ranking score. Records can change after deletion and re-registration. Registry coverage varies, and some records omit dates or restrict access. We show missing data explicitly and do not estimate it.

Know how fresh it is

Results include the retrieval time and a link to the source record. We cache records for up to 15 minutes to reduce repeated registry requests. Age is recalculated using the current UTC calendar date, even when a record is cached. Registry data itself may take longer to update.

How we calculate domain age

We count complete calendar years, months, and days from the registry's registration event to the current date in UTC. Month anniversaries fall on the last day of a shorter month when needed, including leap years. Missing or future creation dates do not produce an estimated age.

Keep research practical

Use the free domain age checker for a detailed record or the bulk domain age checker for a small comparison. CSV exports include sources and timestamps. This service supports small, interactive lookups; it is not a high-volume data feed.

Independent by design

The Domain Age is an independent tool. We are not affiliated with ICANN, IANA, registrars, or the registries whose public records appear in results. Registry terms and notices remain attached to each detailed result.
