Are you looking for the expiry date of a domain name? Any domain registration service can show you the expiry date of a domain, but that requires you to use their search function to look for the domain first, and then find the owner/whois button on that site.
This is a waste of time. You can find the registration date of any domain within seconds, by using your Mac Terminal.
