Date Formatting

DateTime date = new DateTime(2016, 07, 06, 18, 30, 14);
// Format: year, month, day hours, minutes, seconds

Console.Write(String.Format("{0:dd}",date)); 

//Format by Culture info
String.Format(new System.Globalization.CultureInfo("mn-MN"),"{0:dddd}",date);

Since C# 6:

Console.Write($"{date:ddd}");

output :

06
