What is date format for 07th November 2021?

Question

I want the date format as 07th November 2021. Kindly let me know the format.

thanks in advance.

Looks like a custom date format, the `th` part I have no clue, but the rest should be quite straighforward. Check [Custom date and time format strings](https://learn.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings) — Cleptus, Jan 12 '22 at 11:08
You will have to special-case "1st", "2nd" and "3rd", for days > 3 others: "dd'th' MMMM yyyy" — Klaus Gütter, Jan 12 '22 at 11:08
@SᴇM quite close, but that would match `07` but not `07th`. — Cleptus, Jan 12 '22 at 11:09

The tricky part is the "th", becasue it has to mutate to "st"/"nd"/"rd" for the some days of a month.

So these days require special-casing of this ordinal suffix, e.g:

string ordinalSuffix;
if (date.Day == 1 || date.Day == 21 || date.Day == 31)
    ordinalSuffix = "st";
else if (date.Day == 2 || date.Day == 22)
    ordinalSuffix = "nd";
else if (date.Day == 3 || date.Day == 23)
    ordinalSuffix = "rd";
else
    ordinalSuffix= "th";

string formatted = date.ToString($"dd'{ordinalSuffix}' MMMM yyyy");

You surely are aware that this works for English only. To support other languages, you might consider using a library like Humanizer.

What about 21, 22, 23, 30, 31? – phuzi Jan 12 '22 at 11:17

I would store the `st`/`nd`/`rd`/`th` in a variable and do the `ToString` later, just to avoid repeating the `MMMM yyyy`. – Cleptus Jan 12 '22 at 11:18
@phuzi Good catch, edited – Klaus Gütter Jan 12 '22 at 11:18
As @Cleptus stated, I would try and reduce it so that only have a single `date.ToString()` using a variable to store the suffix. – phuzi Jan 12 '22 at 11:29
shorter version can use `%` : `if (date.Day % 10 == 1) ordinalSuffix = "st"` – Dmitry Bychenko Jan 12 '22 at 12:40

Try to use this function here:

        public static string ToStringWithSuffix(this DateTime dt, string format) {   
        // The format parameter MUST contain [$suffix] within it, which will be replaced.   
        int day = dt.Day; string suffix = "";   
        // Exception for the 11th, 12th, & 13th   
        // (which would otherwise end up as 11st, 12nd, 13rd)   
        if (day % 100 >= 11 && day % 100 <= 13) {   
            suffix = "th";   
        }else{
            switch (day % 10) {   
                case 1: 
                    suffix = "st";   
                    break;   
                case 2:
                    suffix = "nd";   
                    break;   
                case 3:   
                    suffix = "rd";   
                    break;  
                default:   
                    suffix = "th";   
                    break;   
            }
        }
        // Convert the date to the format required, then add the suffix.   
    return dt.ToString(format).replace("[$suffix]",suffix);
}

You can call it like so:

DateTime(2021, 2, 21);
Console.WriteLine(dt.ToStringWithSuffix("dd'[$suffix]' MMMM yyyy"));

You can also check the documentation on Custom date and time format strings if you need other formats.

I like your logic, but consider adding a sample call, something like `DateTime dt = new DateTime(2021, 2, 21); Console.WriteLine(dt.ToStringWithSuffix("dd[$suffix] MMMM yyyy"));` — Cleptus, Jan 12 '22 at 11:23
Thanks for the suggestion. I will consider your advice and I will edit my answer! — Alex Florin Ciuciulete, Jan 12 '22 at 11:25
