C# datetimepicker if equals today then tick checkbox, else not checked/uncheck

I am trying to have a check box (notTodayCheckBox) that if the datetimepicker (DateTimePicker) has a selection of today it isn't checked, if the selection is not today it is checked.

My current code ticks the box if the date selected isn't today, but if I change it back to today the box doesn't uncheck.

Current Code:

private void DateTimePicker_ValueChanged(object sender, EventArgs e)
    {
        DateTime check;
        if (DateTime.TryParse(dateTimePicker.Text, out check) && check != DateTime.Now)
            {
                notTodayCheckBox.Checked = true;
            }
        else if (DateTime.TryParse(dateTimePicker.Text, out check) && check == DateTime.Now)
            {
                notTodayCheckBox.Checked = false;
            }
    }
