Assuming the hour on both dates is 00:00, the difference is 30 days. In case of August, it's not 1 month.

Solution 1

You can use subtract on the dates and specify the result you want (hours, days, etc...). Have a look here:

 static void Main(string[] args)
        {
            DateTime dt1 = DateTime.Parse("5/12/2011");
            DateTime dt2 = DateTime.Parse("7/12/2012");
            int days = (dt2 - dt1).Days;
            Console.WriteLine(days);
          
            double month = (dt2 - dt1).Days /30;
            Console.WriteLine(month);
            double year = (dt2 - dt1).Days / 365;
            Console.WriteLine(year);
            Console.Read();

            DateTime oldDate = new DateTime(2012, 8, 1);
            DateTime newDate = new DateTime(2013, 8, 31);
 
            // Difference in days, hours, and minutes.
            TimeSpan ts = newDate - oldDate;
            // Difference in days.
            int differenceInDays = ts.Days;
            int years = (int)(ts.Days / 365.25);
            int months = ts.Days/ 31;

 // to get the difference between two dates
        public static void GetDifference(DateTime date1, DateTime date2, out int Years, out int Months, out int Weeks, out int Days)
        {
            //assumes date2 is the bigger date for simplicity
            //----------------------------------------------
            //years
            TimeSpan diff = date2 - date1;
            Years = diff.Days / 366;
            DateTime workingDate = date1.AddYears(Years);
            while (workingDate.AddYears(1) <= date2)
            {
                workingDate = workingDate.AddYears(1);
                Years++;
            }
            //---------------------------------------------
            //months
            diff = date2 - workingDate;
            Months = diff.Days / 31;
            workingDate = workingDate.AddMonths(Months);
            while (workingDate.AddMonths(1) <= date2)
            {
                workingDate = workingDate.AddMonths(1);
                Months++;
            }
            //---------------------------------------------
            //weeks and days
            diff = date2 - workingDate;
            Weeks = diff.Days / 7; //weeks always have 7 days
            Days = diff.Days % 7;
            //---------------------------------------------
