Hi,
so basically, you want to determin christmas- and newyears eve.
Due to 14day payroll, you cannot use OUTZL RED - am i correct?
Have you considered to give a custom holiday type to these two dates?
Like that, it wouldn't normally be treated as a holiday, but nevertheless you could check on it.
OUTZL HOL with e.g. holidayclass 7 would give you all that you need to fullfill your requirement.
