Hi Try like this DateTime zeroTime = new DateTime(1 1 1); DateTime dt1 = new DateTime(2007 1 1); DateTime dt2 = new DateTime(2008 1 1); TimeSpan span = dt2 - dt1; int days = span.Days; int months = Math.Abs((dt2.Month - dt1.Month) + 12 * (dt2.Year - dt1.Year)); int years = (zeroTime + span).Year - 1; // because we start at year 1 for the Gregorian calendar we must subtract a year here. MessageBox.Show(Days elapsed:  + days); MessageBox.Show(Month elapsed:  + months); MessageBox.Show(Yrs elapsed:  + years); Regards Iftikar

You can use timespan class. It is the best way to get difference between two dates.

try this one using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace dotnetperl { class Class2 { public static void GetDifference(DateTime date1 DateTime date2) { //assumes date2 is the bigger date for simplicity //years int Years; int Months; int Weeks; int Days; TimeSpan diff = date2 - date1; Years = diff.Days / 366; DateTime workingDate = date1.AddYears(Years); while (workingDate.AddYears(1) { workingDate = workingDate.AddYears(1); Years++; } //months diff = date2 - workingDate; Months = diff.Days / 31; workingDate = workingDate.AddMonths(Months); while (workingDate.AddMonths(1) { workingDate = workingDate.AddMonths(1); Months++; } //weeks and days diff = date2 - workingDate; Weeks = diff.Days / 7; //weeks always have 7 days Days = diff.Days % 7; Console.WriteLine(Years:+Years); Console.WriteLine(month: + Months); Console.WriteLine(week: + Weeks); Console.WriteLine(days: + Days); } static void Main(string[] args) { //date in mm/dd/yyyy format DateTime dt1 = DateTime.Parse(09/12/1989); DateTime dt2 = DateTime.Parse(06/02/2003); GetDifference(dt1 dt2); Console.ReadLine(); } } }

Hi vuples i will go through ur article :) In between Iftikar Hussain urs solution is very helpful but when i am removing DateTime zeroTime = new DateTime(1 1 1); & int years=(zeroTime+span).year -1 and replacing with simple equation like int years = dt2.Year - dt1.Year; I am getting same output .. i just wanna confirm is both same ?? else any added adv there ???
