Your domain transfer to Doteasy includes at least a full year of domain registration (depending on your chosen term length), which begins after your current registration expires.
For example, if you have chosen a 1-year term length and your current domain expiry date is June 28, 2020, upon successful transfer to Doteasy, your next expiry date would be June 28, 2021. If you decide to renew your domain, you will be charged to renew your domain 6 days before the domain expiry date.
