How to Calculate days, months, year between two date in C#?

To calculate Day, month, year between two date or simply we can say that age calculation, use the below code:-

DateTime Birth = new DateTime(1947, 8, 15);

DateTime Today = DateTime.Now;

TimeSpan Span = Today - Birth;

DateTime Age = DateTime.MinValue + Span;

       

// Note: MinValue is 1/1/1 so we have to Subtract.

int Years = Age.Year - 1;

int Months = Age.Month - 1;

int Days = Age.Day - 1;

string str = string.Format("Age = {0} Year, {1} Months, {2} Days.", Years, Months, Days);
