Hi VikasKumar, Try this code, But this is sample code, you can modify the code as per your requirement and you can implement much better compare this code... public void Display() { DateTime date = DateTime.Now; System.DateTime BirthDate = new System.DateTime(1991, 9, 11, 0, 0, 0); System.TimeSpan diffResult = date.Subtract(BirthDate); string TotalDays = diffResult.Days.ToString(); string Months = ((diffResult.Days) % 365).ToString(); string RemainingMonths = (Convert.ToInt32(Months) / 31).ToString(); string RemainginYears = ((diffResult.Days) / 365).ToString(); string RemainingDays = (Convert.ToInt32(Months) % 31).ToString(); MessageBox.Show(RemainginYears + "-" + RemainingMonths + "-" + RemainingDays); }

hi try as follows create one funcction in c# as below public static string CalculateYourAge(DateTime Dob) { DateTime Now = DateTime.Now; int _Years = new DateTime(DateTime.Now.Subtract(Dob).Ticks).Year - 1; DateTime _DOBDateNow = Dob.AddYears(_Years); int _Months = 0; for ( int i = 1; i { if (_DOBDateNow.AddMonths(i) == Now) { _Months = i; break ; } else if (_DOBDateNow.AddMonths(i) >= Now) { _Months = i - 1; break ; } } int Days = Now.Subtract(_DOBDateNow.AddMonths(_Months)).Days; return $ "Age is {_Years} Years {_Months} Months {Days} Days" ; } in button click call this function private void bt_click( object sender, EventArgs e) { string _Age = CalculateYourAge (dtdob.Value); lblAge.Text = _Age; }

Hi Dude, Please try this below code it will work: using System; public class Age { public int Years; public int Months; public int Days; public Age(DateTime Bday) { this.Count(Bday); } public Age(DateTime Bday, DateTime Cday) { this.Count(Bday, Cday); } public Age Count(DateTime Bday) { return this.Count(Bday, DateTime.Today); } public Age Count(DateTime Bday, DateTime Cday) { if ((Cday.Year - Bday.Year) > 0 || (((Cday.Year - Bday.Year) == 0) && ((Bday.Month ((Bday.Month == Cday.Month) && (Bday.Day { int DaysInBdayMonth = DateTime.DaysInMonth(Bday.Year, Bday.Month); int DaysRemain = Cday.Day + (DaysInBdayMonth - Bday.Day); if (Cday.Month > Bday.Month) { this.Years = Cday.Year - Bday.Year; this.Months = Cday.Month - (Bday.Month + 1) + Math.Abs(DaysRemain / DaysInBdayMonth); this.Days = (DaysRemain % DaysInBdayMonth + DaysInBdayMonth) % DaysInBdayMonth; } else if (Cday.Month == Bday.Month) { if (Cday.Day >= Bday.Day) { this.Years = Cday.Year - Bday.Year; this.Months = 0; this.Days = Cday.Day - Bday.Day; } else { this.Years = (Cday.Year - 1) - Bday.Year; this.Months = 11; this.Days = DateTime.DaysInMonth(Bday.Year, Bday.Month) - (Bday.Day - Cday.Day); } } else { this.Years = (Cday.Year - 1) - Bday.Year; this.Months = Cday.Month + (11 - Bday.Month) + Math.Abs(DaysRemain / DaysInBdayMonth); this.Days = (DaysRemain % DaysInBdayMonth + DaysInBdayMonth) % DaysInBdayMonth; } } else { throw new ArgumentException("Birthday date must be earlier than current date"); } return this; } } /** * Usage example: * ============== * DateTime bday = new DateTime(1987, 11, 27); * DateTime cday = DateTime.Today; * Age age = new Age(bday, cday); * Console.WriteLine("It's been {0} years, {1} months, and {2} days since your birthday", age.Year, age.Month, age.Day); */

static void CalculateAge() { DateTime dateOfBirth; DateTime.TryParse( "02/18/2008" , out dateOfBirth); DateTime currentDate = DateTime.Now; TimeSpan difference = currentDate.Subtract(dateOfBirth); // This is to convert the timespan to datetime object DateTime age = DateTime.MinValue + difference; // Min value is 01/01/0001 // Actual age is say 24 yrs, 9 months and 3 days represented as timespan // Min Valye + actual age = 25 yrs , 10 months and 4 days. // subtract our addition or 1 on all components to get the actual date. int ageInYears = age.Year - 1; int ageInMonths = age.Month - 1; int ageInDays = age.Day - 1; Console.WriteLine( "{0}, {1}, {2}" , ageInYears, ageInMonths, ageInDays); }

Try like below: String sDate = DateTime.Now.ToString(); // You will take from UI DateTime datevalue = (Convert.ToDateTime(sDate.ToString())); String dy = datevalue.Day.ToString(); String mn = datevalue.Month.ToString(); String yy = datevalue.Year.ToString();
