How much time do I have to renew my domain name after it has expired?

In this article:

TierraNet provides a 30-day renewal grace period for most types of domains (.com, .net, .org, etc). Although your services will be suspended once your domain expires, you will still be able to renew the domain at your regular renewal rate for up to 30 days after the domain's expiration date. 

Please note that we will always encourage domain registrants to renew their domain(s) before their expiration date. It's better to be safe than sorry!
