Well, it's pretty much complicated. As Yui was made to help peoples who would have "depression" (something about "thinking about suicide, always feeling down, etc.." I'm not sure about the english word) about not being able to quit the game world, I doubt that she would be "actively working" during Beta Test, since, normally, players wouldn't feel depressed on a normal game (personal guess there).

So, I'd say she effectively started working on the Nov. 6th.

Now, I said "working" for Jaque355. As I can understand on the being conceived and stuff, all she did on the 6th, was "starting her work as a psychanalist" (or whatever), and not "being born". One could say she was born and worked right away, which could be true, but maybe she was born before, like during the Beta Test time, "registering" normal emotions from Beta Testers, to then take notice of every emotions that are different during the SAO incident to help them.

I'm not sure if that made much sense, but all of that to say that there's no clarification as to say when Yui was effectively "born".
