You can login to your domain manager using the link https://www.enomcentral.com/login.aspx
The login credentials would be the same as that set while purchasing the domain.
Once you login, you would be able to see the registered domains, the expiring domains and also the expired domains (Pic 1 - Domain Manager).
Once you click on the domain you would be able to see the expiration date and also renew it if required.(Pic 2)
