DateTime Struct

Explore how to create and manipulate dates and times using C#'s DateTime struct. Understand its constructors, retrieve current dates, identify days of the week, and add intervals like days or months. This lesson helps you manage precise date-time operations in your .NET applications.

We'll cover the following...

The DateTime struct is a value type that represents any date and time between midnight on January 1, 0001, and 11:59:59 PM on December 31, 9999.

Note: The DateTime struct follows the Gregorian calendar. We must account for this behavior if our application processes dates prior to October 15, 1582.

Creating a DateTime variable

C# 14.0
var dateTimeDefault = new DateTime(); // The minimum value
Console.WriteLine(dateTimeDefault);
var anotherDateTime = DateTime.MinValue; // The minimum value
Console.WriteLine(anotherDateTime);

  • Line 1: We create a DateTime instance using the default constructor, which assigns the lowest possible value.

  • Line 2: We print the default value to the console.

  • Line 4: ...
