That's quite an original understanding of time - if she was born in 1996, then she could have been in 2011 either 15 or 14 (ambiguous due to less than two months between her birthday and release date), but not 16, nope. I would set her at 14, even, as birthdate is correct, as in at least it can be confirmed somewhere else - and it rather takes more than two months to announce and promote releases.
