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

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

Good luck!

How to this in vb.net
E.F. Nijboer 18-Sep-17 12:27pm    
Simply use the Substract in vb.net instead of the minus (-) operator.
d1 - d2 -> d1.Subtract(d2)

C#
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;
           //---------------------------------------------
       }
