I try to get market holiday information for Italy, Netherlands and Greece. Could somebody please tell me the country codes for the function DfListHolidays()? I tried ITA, ITY, NLD, NET and GRC. But I get the error message "Error: ERROR 5000 - Calendars : calendar(s) not found."

If you want to get the calendar style you need to provide three arguments where two are fixed the the third is the ISO currency code. For the countries that currently has EUR you would need to provide the ISO currency code before conversion to EUR.

Netherland 'NLG' - NTL
Italy ITL - ITL
