Holidays (Map)

In many societies there are important distinctions between holidays designated by governments and holidays designated by religious institutions. For example, in many predominantly Christian nations, government-designed holidays may center on Christian holidays, though non-Christians ... may instead observe religious holidays associated with their faith. In some cases, a holiday may only be nominally observed. For example, many Jews in the Americas and Europe treat the relatively minor Jewish holiday of Hanukkah as a "working holiday", changing very little of their daily routines for this day. — en.wikipedia.org
