Doris wandered about the Halloween in different parts of the world here and I'm writing this in response to her post.
In Slovenia we don't make a big deal about Halloween; we carve out pumpkins and people attend Halloween parties and concerts (especially young) but we generally don't make much fuss about it.
October 31st is a work-free day in Slovenia and so is the following day, November 1st. The reason however is not Halloween but another religious holiday celebrated on this day, called Reformation Day.
The Reformation was a Protestant movement in the 16th century attempting to reform the Catholic Church. The first Slovene book and the first mention of the name 'Slovene' is associated with the Reformation and Slovenia has therefore appointed Reformation Day as a national holiday. There is usually an 'official' celebration but it is not really people's holiday.
The following day, November 1, on the other hand, is a firmly rooted national holiday called All Saints Day or simply the Day of the Dead. As the name itself tells, it's the day when we remember our dead. Families gather together, we remember our dear ones, visit their graves, bring flowers, light candles, stop for awhile by their graves, and also meet friends there. People take this holiday very seriously. It therefore suprised me very much when I happened to end up in the Mexican part of Los Angeles years ago on Dia De Los Muertos and witnessed a joyous and lively celebration of November 1st. I liked it.
