"HolidayList" can be:
a text, a text field, a calculation field with text result, a variable, whatever you wish to use but containing a list of dates.
Practically it is better to create an holidays table, each record representing an holiday, then a value list getting its values from that table.

I used this function and it worked perfectly! Thanks a bunch!

For those who it is not working for, be sure you are passing the HolidayList parameter as a list. I have this function called in a calculation field and it looks like:

WorkingDays( GetAsDate(Date Initial) ; GetAsDate(Date Final); List(Holidays::Date)

How is this a recursive function? Is it because it calls itself at the end with: WorkingDays ( DateStart + 1 ; DateEnd ; HolidayList )??

Hi all,

Not sure how to make the holiday list be 'seen' by the function...

Any ideas?

The function seems to have a delay as you scroll through records and it also seems to not work correctly each time (or is it my FileMaker?). In a field I will get a long string of numbers, but if I click in the field, it will suddenly change and display the number of days correctly.
