portuguese hollydays calendar

How/where is imported the hollydays for Portugal ?
I got none on the calendar. How to fix it please.

Hello Jose,
Portugese holidays aren’t unfortunately available on our server by default.
If you are running version 7 though you can subscribe to Internet Calendars.
Just go to Calendar section, open Menu>Tools>Subscribe to Internat Calendar and input http://www.officeholidays.com/ics/ics_country_code.php?iso=PT
(Just as an example - you can search online for other internet calendars that include your holidays)
