I would like to know how can I calculate lifetime of Stack Overflow site from established time until just now? How old is it ?

'' sometimes , questions were from so long times ago , I want to compare them from start-time of SO ''

Go to https://stackexchange.com/ -> All Sites -> Change the view to list view -> You can find the site age in the last column. Here, you can see the age of any site.

To search old questions go to the questions list -> Search for any tag (if required) -> Click on Newest tab -> Click on the last page from paging.

Another way to know exact age of any site without relying on the sites list or questions list is going to the Community user account of that site (http://[site]/users/-1/community) then the "member for" field is actually the age of the site. For example in Stack Overflow:

  • Is that not made up though? Jan 30, 2014 at 10:16
  • @Qantas94Heavy no, I saw Nick (or maybe other dev) mention it at some point and made a mental note. Can't find it now but just try and see for yourself. If you find a site where this isn't true I'll be happy to stand corrected. :) Jan 30, 2014 at 10:19
  • Just the 00:00:00 time sounds suspicious -- on meta.stackoverflow.com/users/-1/community the last seen time is before it was registered, if it's real... Jan 30, 2014 at 10:21
  • @Qantas94Heavy it's 00:00:00 because the whole data was imported from external source (Jeff blog, I think) and as for "last seen" it's fake, a dev just entered it manually at some point. (nobody can really login as that user) Jan 30, 2014 at 10:22
  • @Qantas: balpha mentioned it here (cc @Shadow!)

@hims056 has a really good, efficient, easy answer.

However, if you like to do things the hard way and possibly not get correct results??? You can do it this way :

    FWIW: The oldest question is actually oldest undeleted question. Actual first question is here: stackoverflow.com/questions/1/… (10K) which was quite ridiculous.
