A holiday is a day or other period of time set aside for festivals or recreation. Public holidays are set by public authorities and vary by state or region. Religious holidays are set by religious organisations for their members and are often also observed as public holidays in religious majority countries. Some religious holidays, such as Christmas, have become or are becoming secularised by part or all of those who observe them. In addition to secularisation, many holidays have become commercialised due to the growth of industry.
Holidays can be thematic, celebrating or commemorating particular groups, events, or ideas, or non-thematic, days of rest that do not have any particular meaning. In Commonwealth English, the term can refer to any period of rest from work, such as vacations or school holidays. In American English, the holidays typically refers to the period from Thanksgiving to New Year's, which contains many important holidays in American culture.
The word holiday comes from the Old English word hāligdæg (hālig "holy" + dæg "day"). The word originally referred only to special religious days.
The word holiday has differing connotations in different regions. In the United States, the word is used exclusively to refer to the nationally, religiously, or culturally observed day(s) of rest or celebration or the events themselves, whereas in the United Kingdom and other Commonwealth nations, the word may refer to the period of time where leave from one's duties has been agreed upon and is used as a synonym for the US preferred vacation. This time is usually set aside for rest, travel, or participation in recreational activities, with entire industries targeted to coincide with or enhance these experiences. The days of leave may not coincide with any specific customs or laws. Employers and educational institutes may designate ‘holidays’ themselves, which may or may not overlap nationally or culturally relevant dates, which again comes under this connotation, but it is the first implication detailed that this article is concerned with.
