# timespan difference between 2 times

How do I get the differece in "mm:ss" of 2 timespans in C#
Time1 = "06:00 AM"
Time2 = "06:10 AM"
It must also automatically calc the correct span when it is
Time1 = "11:55 AM"
Time2 = "01:10 PM"

You can add and subtract TimeSpan values like any numeric value. You can add a TimeSpan value to a DateTime value. You can use DateTime.ParseExact to parse a string to a DateTime value. You can subtract two DateTime values to get a TimeSpan value:
``````TimeSpan Time1 = TimeSpan.FromHours(6);
TimeSpan Time2 = TimeSpan.FromHours(6) + TimeSpan.FromMinutes(10);

TimeSpan diff = time2 - Time1; // result is 10 minutes

Console.WriteLine((DateTime.Today + diff).ToString("hh:mm tt")); // outputs "00:10 AM"
Console.WriteLine((DateTime.Today + diff).ToString("HH:mm")); // outputs "00:10"

DateTime Date1 = DateTime.ParseExact("11:55 AM", "hh:mm tt", CultureInfo.InvariantCulture);
DateTime Date2 = DateTime.ParseExact("01:10 PM", "hh:mm tt", CultureInfo.InvariantCulture);

TimeSpan diff2 = Date2 - Date1; // result is 75 minutes

Console.WriteLine((DateTime.Today + diff2).ToString("hh:mm tt")); // outputs "01:15 AM"
Console.WriteLine((DateTime.Today + diff2).ToString("HH:mm")); // outputs "01:15"
