You might also want to mention that the formatting is available through the .toString() method as well as the string.Format one.

DateTime dt = new DateTime();
string formattedDate = dt.toString("dd/MM/yyyy");

Great article.Thanks. But what if I need something like 2nd January,2013??
Thanks in advance.

@Prasun,

You will have to write your own method to generate the ordinal suffix based on the date, and then build your own string using that. There is no short cut formatter for what you want that I know of.

The short date option (d) doesn't include leading zeros in month and day, so it would actually render 8/4/2007. To get the leading zeros the format needs to be spelled out: MM/dd/yyyy or dd/MM/yyyy. http://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx has all the formats you never use...

- Mike

@Bob

The "d" option (short date) is culture specific. Leading zeros are omitted if your culture is en-US. They are retained for en-GB.

- Jomon John

It's good.
Thank you....

i need date format "mmm yyyy". Ex : Mar 2015, what is the specifier ??

- Mike

@akil,

You need capital Ms: "MMM yyyy"

DateTime.Now.ToString("MMM yyyy")

- Andreas

Helpful article!

Is there any option to display the date format as days since 01/01/1900

e.g. 21/08/2015 as 42237

Thanks in advance.

DateTime Pickupdate = DateTime.ParseExact("5-Jan-2016 05:30 PM", "dd-MMM-yyyy hh:mm tt", System.Globalization.CultureInfo.InvariantCulture);

some time works some time not why?

- Mike

@vartika,

You have a placeholder in your format string for a double digit day, but the string representation of the datetime value is missing the leading 0 from the day part. It will work if you pass in "05-Jan-2016 05:30 PM".

This is great
