well, start by printing month(i), day(i), year(i) to the screen... it
might tell you, that, hum, year(i) is zero.
In this case, you have a problem reading your file.
Also, you say that you have Month, Year in your file, and now you also
use a Day....

I would say put a breakpoint in your program and see if you
can find out why the assumptions you are making about your
data are all wrong. :-)
