 That is perfect for 1 date scope. What if I have a meeting to schedule 
 in a month (eg. March) and (according to other meeting attendees) the 
 meeting can only happen from 10-15, 19, 20-28 and 30. Do I have to make 
 a data-list with every possible day? What if I would like to set a 
 future event that cannot happen on weekends?
