Calculations with dates help

[surfingmike]

I am new to file maker pro, but so far think it will be very helpful and am already looking here for help because the FMP phone tech was not very helpful. I am hoping someone here can be...

I am running FMP 9.0 on XP, and have a database of highschool students. One of my desired fields is to have the birthdate of the student and their current age based on todays date. I set the field up to "calculation" and assumed I could put the following calculation:

age = // - Birthdate

When I did this I would get a number like 4783. In this first case, the student's b-day wassomething like 4/17/1995

Can anyone offer me assistance on how to properly write the calculation? please?

My second question is related to the first, but i would also like to have a calculation that automatically advanes the students grade level (ex. 9, 10, 11,...etc) at the end of June when graduation takes place. Again, any help ould be appreciated.

*Apologies if I posted in the wrong section.
