Calculate remaining # of days between 2 dates

[Potato2009]

I know I may use Datedif(startdate, enddate,"d") to get # of days between 2 dates, but I have to calculate the exact number of months and then the remaining number of days seperately.

For example, startdate=June 15, 2007 and enddate=August 7, 2009, then Datedif(startdate, enddate, "m")=25, but how to get the remaining # of days which is 23?

Thanks!
