Answer 1

//default locale
System.DateTime.Now.DayOfWeek.ToString();
//localized version
System.DateTime.Now.ToString("dddd");

To make the answer more complete:

• DayOfWeek MSDN article

• If localization is important, you should use the "dddd" string format as Fredrik pointed out - MSDN "dddd" format article

Thighbone

I wouldn't use the ToString. If you need it for comparisons or storage, just use the enum value. Otherwise, using the dddd format specifier as in Fredrik's answer is better for localization. – Opposable

The localized version is not correct and gives a compiler error. It should be System.DateTime.Now.ToString("dddd"); – Egoism

Answer 2

If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeek will do the job.

If you want to display the day of week to the user, DateTime.Now.ToString("dddd") will give you the localized day name, according to the current culture (MSDN info on the "dddd" format string).

Answer 3

System.Threading.Thread.CurrentThread.CurrentUICulture.DateTimeFormat.GetDayName(System.DateTime.Now.DayOfWeek)

or

System.Threading.Thread.CurrentThread.CurrentUICulture.DateTimeFormat.GetDayName(DateTime.Parse("23/10/2009").DayOfWeek)

Answer 4

DateTime.Now.DayOfWeek quite easy to guess actually.

for any given date:

   DateTime dt = //....
   DayOfWeek dow = dt.DayOfWeek; //enum
   string str = dow.ToString(); //string

Ahearn

or to keep more simple Datetime dt; string date = dt.DayOfWeek.ToString() – Polacre

Answer 5

Here is more simple

DateTime dt;
string yourdate = dt.DayOfWeek.ToString()

better than declare redundant DayOfWeek

Answer 6

DateTime now = DateTime.Now
string s = now.DayOfWeek.ToString();

Answer 8

You're looking for the DayOfWeek property.

Here's the msdn article.

Answer 9

I use this Extension Method:

public static string GetDayName(this DateTime date)
{
    string _ret = string.Empty; //Only for .NET Framework 4++
    var culture = new System.Globalization.CultureInfo("es-419"); //<- 'es-419' = Spanish (Latin America), 'en-US' = English (United States)
    _ret = culture.DateTimeFormat.GetDayName(date.DayOfWeek); //<- Get the Name     
    _ret = culture.TextInfo.ToTitleCase(_ret.ToLower()); //<- Convert to Capital title
    return _ret;
}

Answer 10

What about if we use String.Format here

DateTime today = DateTime.Today;
String.Format("{0:dd-MM}, {1:dddd}", today, today) //In dd-MM format
String.Format("{0:MM-dd}, {1:dddd}", today, today) //In MM-dd format

Answer 11

(DateTime.Parse((Eval("date").ToString()))).DayOfWeek.ToString()

at the place of Eval("date"),you can use any date...get name of day

Answer 13

using System;

class Program
{
    static void Main()
    {
        DateTime now = DateTime.Now;

        // Format today's date as "yyyy/MM/dd"
        var today = now.ToString("yyyy/MM/dd");

        // Get the current day as a string
        var day = now.Day.ToString();

        Console.WriteLine("Today's date: " + today);
        Console.WriteLine("Current day: " + day);
