How to restrict datetimepicker to weekdays and save it?

Question

I need to know how am I able to restrict datetimepicker to weekdays, so the user can only select days from Monday to Friday.

Since now it is only displaying the weekday as inserted in Custom Format (DateTimePicker Properties) an I will also need it to only save the "name" of the days of the week and not the whole field with time and day/month/year.

Thank you
