C# DayOfWeek Enum

This C# article demonstrates the DayOfWeek enum type. It contains Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.

DayOfWeek. Seven days are in each week.

We determine if a certain date is a Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday. The DayOfWeek property, and the DayOfWeek enum type, can be used for this purpose.

Example. To begin, we look at a program that acquires the current DayOfWeek. You can use either DateTime.Now or DateTime.Today to get the current day. And then you can take the DayOfWeek from the DateTime instance.


Next: We show how to test what day of the week was found using an if-expression.

And: We finally print out all the values of the DayOfWeek enum for completeness.


Based on:

.NET 4

C# program that uses DayOfWeek enum

using System;

class Program
    static void Main()
	// Get currrent day of week.
	DayOfWeek today = DateTime.Today.DayOfWeek;
	Console.WriteLine("Today is {0}",

	// Test current day of week.
	if (today == DayOfWeek.Monday)
	    Console.WriteLine("DO WORK");

	// Demonstrate all DayOfWeek values.
	Console.WriteLine("{0}, {1}, {2}, {3}, {4}, {5}, {6}",


Today is Monday
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday

Selection statement on DayOfWeek. You can use an if-expression or a switch statement with the DayOfWeek enum. If you have to take different actions based on every day, you could use a switch statement and then execute code as required.

Note: In the example output, the DO WORK line only appears if the program was run on a Monday.


Summary. The DayOfWeek enum provides a handy encoded type for representing the day of the week as a small value. This type can be used anywhere. It is not tied to the DateTime type or the DayOfWeek property accessor.
