How do i find out the Age of a Domain?

[aleksis]

How do I find out the real age of a domain? When it was very first registered on a service like NameCheap, GoDaddy, etc..? I didn't give this much thought until i just recently registered a domain and was thinking, although i am registering this domain on NameCheap, it doesn't mean im the first one to do it, it could have been owned many years ago, then left to run out and is now available again.
