Once a domain name leaves the REDEMPTION PERIOD status it goes into PENDING DELETE status.
Under most circumstances, a registrar will not allow for you to renew yoru domain name once it has reached PENDING DELETE status. There are some rare exceptions (and it also depends on the registrar).
Under rare circumstances, a domain will not enter the PENDING DELETE status and will be dropped immediately after being removed from REDEMPTION PERIOD.
A domain name will drop, and become available for registration six days after it changes status to PENDING DELETE. Under some circumstances, a domain name can drop in 5 days instead of 6.
