The word holiday has related but different meanings in English-speaking countries. Based on the words holy and day, holidays originally represented special religious days. The word has evolved in general usage to mean any special day of rest (as opposed to regular days of rest such as the weekend).
In most of the English-speaking world a holiday is also a period spent away from home or business in travel or recreation (e.g. "I'm going on holiday to Malta next week"), the North American equivalent being "vacation". However, some Canadians (especially those of English or Irish descent) will use both the terms vacation and holiday interchangeably when referring to a trip away from home or time off work.
In Canada and the United States, a holiday is a day set aside by a nation or culture (in some cases, multiple nations and cultures) typically for celebration but sometimes for some other kind of special culture-wide (or national) observance or activity. A holiday can also be a special day on which school and/or offices are closed, such as Labor Day.
