How to modify static variable at runtime to pass data from one form to another in Windows Forms Application

I have created the static class with static variable Date

public static class Class1
{    
    public static DateTime date;
}

In the DatePicker event of ValueChanged i am assigning the value of DatePicke to static variable.

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
    Class1.date = this.dateTimePicker1.Value;
    Form2 f2 = new Form2();
    f2.Show();
    this.Hide();
}

Here i have shown how to increament the static variable value

private void Form2_Load(object sender, EventArgs e)
{            
    this.lblSelectedDate.Text = Class1.date.ToString();
    this.lblIncreamentedDate.Text = Class1.date.AddDays(1).ToString();
}
