There are two kinds of public holidays in Slovenia - state holidays and work-free days. State holidays are those celebrated by the state. These include official functions and flying the national flag. The latter are actually Catholic religious holidays, which are equivalent to any Sunday: companies and schools are closed, but there is no official celebration.
There are 13 state holidays and additional 4 work-free days in Slovenia. Two of them always fall on Sunday, thus, there are effectively at most 15 days of work-free days in Slovenia.
