Age of an expired domain, Namecoin Domains and Assets (NFT)

Hey Namepros,

In case you missed it there have been people registering expired Namecoin domains and assets. Namecoin is an old decentral DNS project an you can register domains, that you need to renew, it has a blockchain ect. Without explaining what namecoin is the question I have is as follows.

If the domain was registered in 2011 and then expired in 2013 but was registered again in 2022 what is its age?

For a legacy domain (.com .info .org ect) What tools do you use to get the true age of a domain?
