Math question

I know, that is what everyone wants to see when they tune into a blog, but here it is anyway. What is the first date on which all 8 digits will differ? (note, I have limited you to the 9000 years between 999 and 9999, but I think you can handle it. I am also giving you a hint of sorts.

As an aside, when you get an answer, how did you come to it? Could you think of an "algorithm", or was it just trial and error? Or, (hint, hint) did it seem like trial and error but really have a pattern underlying?

The answer is in the comments...
