I’m making some slight changes to my web hosting billing.  If I am managing your domain name registration as well as web hosting, I’ll be aligning your annual web hosting to become due at the same time as your domain name registration - this way they are in alignment with each other and it serves as an extra reminder for me should I lose track of the billing.  To me it just makes sense to have them occurring at the same time. If you are paying monthly or quarterly, then you needn’t worry as this will remain as is.
