This property contains the same type of information and is edited in the same manner as any the a-e-i-o-u Holidays. The difference comes from the use that is made of the holidays sets in it.
You should add Holidays Sets to the Included Holidays property whenever you refer to Holidays Sets specifically by their ID number in Macros. This will usually be necessary whenever you use one of the following macro functions : HolidayOfSetInPeriod, HolidayOfSetOnDate, IsHolidayForSet, and IsHolidayOccurence.
