It's not necessary to go that far for something that just needs to parse a 
date, which is just three numbers.

It can be kept simple, but restricting it to years 2000 to 2099 is 
inadvisable (most dates of birth, for example, will be from last century).

In the OP's example, replacing 20%.2d (what does the "." do?) by %4d might 
be all that's needed. (And I would also allow 2-digit years, converting to 
the most likely 19xx or 20xx form where it's reasonably unambiguous.)
