What is domain age?
Domain age usually describes how long a name has been registered according to public creation timestamps. It differs from “site age” because a domain may be parked, redirected, or quiet for years while a separate property does the real work. Registration data lives in operator-maintained directories that follow ICANN rules, and modern access often flows through RDAP with WHOIS as the familiar interchange format. Privacy and local law can hide registrant names while still exposing the timeline of the name itself.
When you paste a hostname here, we normalize it, query those public sources, and translate the answer into human years and months plus calendar dates. Treat the number as operational context—helpful when comparing vendors, vetting acquisition targets, or documenting due diligence—not as a mystical ranking factor.
