Godaddy policy:
From ICANN's Expired Registration Recovery Policy (ERRP):
So if someone bids on the 26th day and then GoDaddy prevents the original registrant from renewing it then it effectively reduces the RGP to 25 days.+26 days: Domain goes to auction, but you can still manually renew the domain for the standard renewal price. If there's an active bid at auction, the domain cannot be renewed.
From ICANN's Expired Registration Recovery Policy (ERRP):
The ERRP requires all generic TLD registries to offer a Redemption Grace Period ("RGP") of 30 days immediately following the deletion of a domain name registration. During this 30-day period, registries are prohibited from transferring the domain name, and must allow the registered name holder of the domain name to restore the domain name registration. If you are the registered name holder of a domain name that has been deleted by your registrar and want to restore your domain name registration during this Period, you can contact your registrar for assistance. Note that your registrar may charge a fee for this service.
Domain names that are in the 30-day Redemption Grace Period can be redeemed (or renewed) before the end of the Grace Period. If you tried to redeem (or renew) your domain name that is in Redemption Grace Period, but were unable to do so, the registrar may be in breach of the Expired Registration Recovery Policy. Your registrar must provide three renewal notices and allow a domain in Redemption Grace Period to be redeemed (or renewed).
