c# - change the color of a specific date on date picker control for specified dates C# Winforms

Question

I am working on a C#/WinForm Application. The user when he activates the datepicker would like to see at a glance up and coming holidays by having the timepicker show them in red.

I have been playing around with the datetimepicker class events and properties below is an example of what I came up with:

DateTime decemberholiday =  new DateTime(2013,12,25);
        dateTimePicker1.Value = decemberholiday;
        if (dateTimePicker1.Value == decemberholiday) {

            dateTimePicker1.CalendarForeColor = Color.Red;

I know it is setting the date to the specific date instead of displaying the actual date but this was something i came up with for quick testing purposes. When I run the program - nothing changes. Any input would be appreciated.
