DateTime EndDate = Convert.ToDateTime(weekEndDate);

What is the culture on your server. Is it one that accepts dates in the format `dd/MM/yyyy`? — , May 20 '16 at 07:06

Try changing your string format to "yyyy-mm-dd" or "yyyy/mm/dd"

You can also use DateTime.TryParse method to parse date from any date format. See examples

You can use ParseExact method to parse the string into DateTime.

string weekEndDate = "20/05/2016";
DateTime EndDate = DateTime.ParseExact(weekEndDate, "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture);

Or you can use TryParseExact it will not throw exception if string is not parsed into DateTime

DateTime.TryParseExact(weekEndDate, "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture, DateTimeStyles.None, out EndDate);

Use TryParseExact

string d1 = "11/18/2016 11:45:44 AM";
string d2 = "11/18/2016 11:45:59 AM";

DateTime frmdate;
DateTime todate;
CultureInfo enUS = new CultureInfo("en-US");
bool f = DateTime.TryParseExact(d1, "M/dd/yyyy HH:mm:ss tt", enUS, DateTimeStyles.None, out frmdate);
bool t = DateTime.TryParseExact(d2, "M/dd/yyyy HH:mm:ss tt", enUS, DateTimeStyles.None, out todate);

TimeSpan val = frmdate - todate;
