Definition: Returns people with the contents of the Special Date field in their active profile. This field is optional so it may be blank. Use this field to store a date that is used during staffing (e.g., Hire Date).
Return value: Values of type Date.
Source: The Advanced TAB of the Person Profile window.
Sorting: If this base rule is used for sorting in a List Target or a List, then people with a blank Special Date field are pushed behind the other candidates in an ascending sort; otherwise, they are preferred (sorted to the top) if the sort is descending.
