How to see when my SSL certificate expires?
You can see the expiration time in days, as well as the date, at the very top of the SSL monitoring page.
In this example, apple.com certificate will expire in 268 days, valid until May 19, 2023.
Downtime will regularly load a website to update the certificate expiration date and notifies you in case it will expire soon.
