It is possible to do it at any time by the renewal deadline we set.
You will receive the invoice for the renewal one month before the renewal deadline, so please pay by the renewal deadline.
Even if you renew before the renewal deadline, the renewal years will be extended from the domain registration deadline.
Please note that domains that have passed the renewal deadline can be renewed only within the “renewal grace period”, and restoration only within the “restoration grace period”, but there is no guarantee that the renewal will be completed.
(Some domains do not have a “grace period”)
