Don't use strings ... use DateTime values.
First, convert your string based date to a DateTime using the DateTime.TryParse Method[^] and allows you to tell the user when he enters a "bad date".
Then subtract the two dates and you will get a TimeSpan[^]. This has a TimeSpan.TotalDays Property[^] which gives you want you need.

private void countDate()
{
DateTime xmas = new DateTime(2018,12,25);
double daysUntilChristmas = DateTime.Today.Subtract(xmas).TotalDays;
label5.Text = Convert.ToString(daysUntilChristmas);
}

2nd.
dateTimePicker2.Value = DateTime.Now;
int daysDiff = ((TimeSpan)(dateTimePicker2.Value.Date - dateTimePicker1.Value.Date)).Days;
label5.Text = daysDiff.ToString();
