[EVA] [Eva] Asuka's Birth Year (yet again)

[Michael Wignall]

I am sure this has been discussed here before, and
I did go searching through the archives but couldn't 
find what I was looking for...

How do we know that Asuka is born in 2001?

That is her birthday is the 4th of December 2001.
Which would make her 13 when the series starts.
