The property Now is returning the reference to an data object. That can be accessed as objects to.

You only must return an object of that type in the property getter.

Some explanation and more complex examples to getters and setters in C#.

like this

public class MyDateTime {
       public static MyDateTime My_Now { get;  }
       public int My_Year { get; }
   }

int year = MyDateTime.My_Now.My_Year;

It's simply because the property returns an object so you can then access the properties of the object it returns.

public class Data
{
    public int ID { get; set; }
    public string Name { get; set; }
}

public class MyClass
{
    public Data Data { get; set; }

    public MyClass()
    {
        this.Data = new Data();
    }
}

MyClass c = new MyClass();
c.Data.ID = 1;

In the above the Data property is a property of the object, if you make it static then it is a property of the type and that emulates DateTime.Now better

public class MyClass
{
    public static Data Data
    {
        get
        {
            return new Data();
        }
    }
}

MyClass.Data.ID = 1;
