Well, I won't touch that comment on your math skills.
But I wonder if you aren't assuming certain things 
that aren't true.

In 1998 Harry defeated Voldemort. Five years* later,
he and Ginny married can began having kids. Four 
years after that, for a total of 9 years, Harry is
promoted to Head of the Auror's Office.

1998
+_ 5
+_ 4
_______
2007
 
Ten more years after that, we see the Epilog, 
making the year 2017.

If we assume, James is age 13 in the Epilog, then
this also adds up. 1998+5+13 = 2016, which would
imply that James turns 14 later in the school year.

We don't really know what year James is in in school.
All we know is he is returning to school and he has
a younger brother who is likely 11 years old. So, he
could be 12, 13, or age 14 and still reasonably fit
the time line. 

So,...more or less... everything does add up.
