They are lot of utilities available to notify the expiry date of the SSL certificate and most of them depends upon the application specific. For simplicity, you can write your own script or code and you can customize the things more simpler. even you can do with openssl or keytool to run in a cron job to send a mail or sms automatically.


Could literally just use the calendar on your phone or computer, and/or CalDAV if you want to schedule programmatically. Could also use something like Gmail Delay Send to e-mail yourself in the future if you are worried that DigiCert or Symantec will forget to hit you up for money around that time.


If running on linux, certmonger does exactly that: it keeps track of certificates, and if you have libraries setup for it, warns you when these are close to expiry and if librsries for this are available and configured, also takes action automatically (like submitting a certificate for renewal, receiving the new one, installing it where needed and even refreshing daemons afterwards).

This is, of course, all dependent on having the correct plugins in place for such actions, or writing your own in python if they don't exist yet. From my experience, for instance, it integrates very well with Fedora's IPA (RedHat's IdM) solution, part of which is a CA.
