At Nucleus we work with to dates:
Renewal date : The day for which you must renew.
Deletion date : The day that your domain will be put out of order.
40 days prior to the renewal date you will receive weekly notices to renew your domain.
The renewal must be completed before the renewal date. If we do not receive a renewal before the renewal date, the domain will automatically be put out of order on the deletion date. If you choose to pay by bank transfer, we need to receive the payment before the renewal date.
You can always consult your renewals through the Control panel.
