In this case, I find it much simpler to have the date as a field in the table. The only reason to keep a separate table for dates is, if you need to store specific information that belongs to dates, and not to individual appointments. Like Agnes said, for holidays. You can store additional information about holidays, e.g., what are you celebrating. In any case the "child table" appointments would still have the date.
