TLS and domain
Domain expiry checker
Check when a domain registration expires and who it is with.
What this checks
A domain has to be renewed, and if the registration lapses the site and its email go dark, sometimes within hours. This tool looks up the registration using RDAP, the modern replacement for WHOIS.
It shows when the domain was registered, when it expires, how many days are left and which registrar it is with.
Why it matters
A lapsed domain is one of the worst ways to lose a client: the site disappears, email stops and someone else can grab the name. It is entirely avoidable.
Renewal reminders go to an inbox that may not be watched, so an independent check matters.
How to fix common failures
Turn on auto-renew
Enable auto-renew at the registrar and keep a valid card on file.
Confirm the contact email
Make sure renewal notices go somewhere a human actually reads.
Track it independently
Watch the expiry date separately from the registrar so a missed email does not mean a lost domain.
Domain expiry checker is one check. Janitor watches domain registration expiry automatically across every client site and puts it in a branded report.

FAQ
Domain expiry checker FAQ
What is RDAP?
RDAP is the Registration Data Access Protocol, the modern, structured replacement for WHOIS. It returns registration and expiry dates over HTTP.
Why is some data missing for my domain?
Not every registry exposes the same fields over RDAP, and some redact details. Expiry and registration dates are usually available; registrar name is not always.
Can Janitor watch domain expiry for me?
Yes. Janitor tracks domain registration expiry on every client site and warns you well before it lapses.
