DateTime today = DateTime.Today;
DateTime after2week = today.AddDays(14);
DateTime after4weeks = today.AddDays(28);
Label1.Text = "today= " + today.ToLongDateString();
Label1.Text += "<br /><br />after added two weeks with today=";
Label1.Text += after2week.ToLongDateString();
Label1.Text += "<br /><br />after added 4 weeks with today=";
