You may have to take a look at: http://msdn.microsoft.com/en-us/library/03ybds8y(v=VS.100).aspx

This may start you up

FindQuarter(DateTime startDate, DateTime endDate) // 01-10-09, 01-06-10
{
    startDateQuarter = GetQuarter(startDate.Month); // 2
    endDateQuarter = GetQuarter(endDate.Month);  // 1
    endDateQuarter += (endDate.Year - startDate.Year) * 4; // 5
    // fill up startDateQuarter to endDateQuarter into a list 
    // and return it // 2,3,4,5
}

GetQuarter(int month) // 6
{
    int quarter;
    // check the month value and accordingly assign one of the basic quarters 
    // using if-else construct ie, if(month>=6 && month<=8){ quarter = 1 };
    return quarter; // 1 
}

Instead of GetQuarter() method, you can also use a dictionary to store your month to quarter mappings

Dictionary quarter = new Dictionary();
quarter.Add(1,1);  //of the format Add(month,quarter)
quarter.Add(2,1);
...

Now instead of GetQuarter(someDate.Month); you can use quarter[someDate.Month];
