DateTime Format C#
Date and Time in C# are handled by DateTime class in C# that provides properties and methods to format dates in different datetime formats. This article blog explains how to work with date and time format in C#.
The following table describes various C# DateTime formats and their results. Here we see all the patterns of the C# DateTime, format, and results.
DateTime.Now.ToString("MM/dd/yyyy") //Res: 05/29/2015
DateTime.Now.ToString("dddd, dd MMMM yyyy") //Res: Friday, 29 May 2015
DateTime.Now.ToString("dddd, dd MMMM yyyy") //Res: Friday, 29 May 2015 05:50
DateTime.Now.ToString("dddd, dd MMMM yyyy") //Res: Friday, 29 May 2015 05:50 AM
DateTime.Now.ToString("dddd, dd MMMM yyyy") //Res: Friday, 29 May 2015 5:50
DateTime.Now.ToString("dddd, dd MMMM yyyy") //Res: Friday, 29 May 2015 5:50 AM
DateTime.Now.ToString("dddd, dd MMMM yyyy HH:mm:ss") //Res: Friday, 29 May 2015 05:50:06
DateTime.Now.ToString("MM/dd/yyyy HH:mm") //Res: 05/29/2015 05:50
DateTime.Now.ToString("MM/dd/yyyy hh:mm tt") //Res: 05/29/2015 05:50 AM
DateTime.Now.ToString("MM/dd/yyyy H:mm") //Res: 05/29/2015 5:50
DateTime.Now.ToString("MM/dd/yyyy h:mm tt") //Res: 05/29/2015 5:50 AM
DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss") //Res: 05/29/2015 05:50:06
DateTime.Now.ToString("MMMM dd") //Res: May 29
DateTime.Now.ToString("yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss.fffffffK") //Res: 2015-05-16T05:50:06.7199222-04:00
DateTime.Now.ToString("ddd, dd MMM yyy HH’:’mm’:’ss ‘GMT’") //Res: Fri, 16 May 2015 05:50:06 GMT
DateTime.Now.ToString("yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss") //Res: 2015-05-16T05:50:06
DateTime.Now.ToString("HH:mm") //Res: 05:50
DateTime.Now.ToString("hh:mm tt") //Res: 05:50 AM
DateTime.Now.ToString("H:mm") //Res: 5:50
DateTime.Now.ToString("h:mm tt") //Res: 5:50 AM
DateTime.Now.ToString("HH:mm:ss") //Res: 05:50:06
DateTime.Now.ToString("yyyy MMMM") //Res: 2015 May
Details:
- d -> Represents the day of the month as a number from 1 through 31.
- dd -> Represents the day of the month as a number from 01 through 31.
- ddd-> Represents the abbreviated name of the day (Mon, Tues, Wed, etc).
- dddd-> Represents the full name of the day (Monday, Tuesday, etc).
- h-> 12-hour clock hour (e.g. 4).
- hh-> 12-hour clock, with a leading 0 (e.g. 06)
- H-> 24-hour clock hour (e.g. 15)
- HH-> 24-hour clock hour, with a leading 0 (e.g. 22)
- m-> Minutes
- mm-> Minutes with a leading zero
- M-> Month number(eg.3)
- MM-> Month number with leading zero(eg.04)
- MMM-> Abbreviated Month Name (e.g. Dec)
- MMMM-> Full month name (e.g. December)
- s-> Seconds
- ss-> Seconds with leading zero
- t-> Abbreviated AM / PM (e.g. A or P)
- tt-> AM / PM (e.g. AM or PM
- y-> Year, no leading zero (e.g. 2015 would be 15)
- yy-> Year, leading zero (e.g. 2015 would be 015)
- yyy-> Year, (e.g. 2015)
- yyyy-> Year, (e.g. 2015)
- K-> Represents the time zone information of a date and time value (e.g. +05:00)
- z-> With DateTime values represents the signed offset of the local operating system's time zone from
Coordinated Universal Time (UTC), measured in hours. (e.g. +6) - zz-> As z, but with leading zero (e.g. +06)
- zzz-> With DateTime values represents the signed offset of the local operating system's time zone from UTC, measured in hours and minutes. (e.g. +06:00)
- f-> Represents the most significant digit of the seconds' fraction; that is, it represents the tenths of a second in a date and time value.
- ff-> Represents the two most significant digits of the seconds' fraction in date and time
- fff-> Represents the three most significant digits of the seconds' fraction; that is, it represents the milliseconds in a date and time value.
- ffff-> Represents the four most significant digits of the seconds' fraction; that is, it represents the ten-thousandths of a second in a date and time value. While it is possible to display the ten-thousandths of a second component of a time value, that value may not be meaningful.
- fffff-> Represents the five most significant digits of the seconds' fraction; that is, it represents the hundred-thousandths of a second in a date and time value.
- ffffff-> Represents the six most significant digits of the seconds' fraction; that is, it represents the millionths of a second in a date and time value.
- fffffff-> Represents the seven most significant digits of the second's fraction; that is, it represents the ten-millionths of a second in a date and time value.
Here is a complete C# code sample that uses these formats.
using System;
namespace FormatDateTime
{
public class DateTimeFormatter
{
public static string DateTimeFormatter(int type, DateTime dateTime)
{
var result = string.Empty;
switch (type)
{
case 1: result = dateTime.ToString("MM/dd/yyyy"); break;
case 2: result = dateTime.ToString("dddd, dd MMMM yyyy"); break;
case 3: result = dateTime.ToString("dddd, dd MMMM yyyy"); break;
case 4: result = dateTime.ToString("dddd, dd MMMM yyyy"); break;
case 5: result = dateTime.ToString("dddd, dd MMMM yyyy"); break;
case 6: result = dateTime.ToString("dddd, dd MMMM yyyy"); break;
case 7: result = dateTime.ToString("dddd, dd MMMM yyyy HH:mm:ss"); break;
case 8: result = dateTime.ToString("MM/dd/yyyy HH:mm"); break;
case 9: result = dateTime.ToString("MM/dd/yyyy hh:mm tt"); break;
case 10: result = dateTime.ToString("MM/dd/yyyy H:mm"); break;
case 11: result = dateTime.ToString("MM/dd/yyyy h:mm tt"); break;
case 12: result = dateTime.ToString("MM/dd/yyyy HH:mm:ss"); break;
case 13: result = dateTime.ToString("MMMM dd"); break;
case 14: result = dateTime.ToString("yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss.fffffffK"); break;
case 15: result = dateTime.ToString("ddd, dd MMM yyy HH’:’mm’:’ss ‘GMT’"); break;
case 16: result = dateTime.ToString("yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss"); break;
case 17: result = dateTime.ToString("HH:mm"); break;
case 18: result = dateTime.ToString("hh:mm tt"); break;
case 19: result = dateTime.ToString("H:mm"); break;
case 20: result = dateTime.ToString("h:mm tt"); break;
case 21: result = dateTime.ToString("HH:mm:ss"); break;
case 22: result = dateTime.ToString("yyyy MMMM"); break;
default:
break;
}
return result;
}
}
}
Result For: Type = 2, DateTime = "Jan 01, 2021"
Friday, 01 January 2021
