FAQ

Where does the creation date come from?
From a live WHOIS lookup — the exact same data source as the WHOIS Lookup tool, not a separate estimate. If WHOIS doesn't return a creation date for a domain, this tool says so instead of guessing.
Is the age calculation exact?
Yes — it's calendar-correct (accounting for actual month lengths and leap years), not a naive days ÷ 365 approximation.
