>Will that actually list the dates, or just the number of dates?

Hmm your question was not clear to me. It'd return day count between dates. I think no built-in thing to return those dates but you could simply loop. ie: in C#:

 private static ArrayList DaysBetweenDates(DateTime start, DateTime end)
 {
   ArrayList days = new ArrayList();
   DateTime startDate = start.Date;
   DateTime endDate   = end.Date;
   int daycount = (endDate - startDate).Days;
   for(int i=0;i<=daycount;i++)
   {
     days.Add(startDate.AddDays(i));
   }
   return days;
 }
