No, that’s not the date that the “person” joined, but that’s the date that the “Page” was created. And once a page is created, the name can be changed later in the future. So ... you just create a page, sit around and wait for some big “news event” - change the name to that news event - and “get a lot of likes” ... :-)
Yes I know, my wife told me. She is on facebook. I don’t want to be on facebook so I really know nothing about it, but she told me taht the date is the date the [age is created. Thanks for adding the point about creating these pages and then changing names to get a lot of likes. I guess that is important to some. Whatever floats their boat I say.
