A holiday is a regularly reoccurring festive day. Usually, but not always, the festive day is observed every year. The word "holiday" is derived from the words "holy" and "day." In British English, the word "holiday" is used to refer to a Vacation as well as a public holiday.^[1]

Long holidays with no work

• Spring Festival, May Day, and National Day (People's Republic of China)
• Golden Week (Japan)
• The Majówka, also called the Picnic (Poland)
• Holy Week, sometimes with Easter, St. Patrick's Day, Easter Monday and Good Friday (Ireland)
• A long weekend, when a holiday is next to the weekend (Australia and England).
• In the United States, Dr. Martin Luther King, Jr. Day, Presidents' Day, Memorial Day and Labor Day are always on Monday to create a "long weekend" or "3-day weekend".

Other holidays like America's Independence Day and Veterans' Day can come on a weekday or weekend. If the holiday is on a weekend, it is moved to Friday or Monday to create a "3-day weekend." Calendars sometimes mark these holidays twice. For example, in 2006, Veterans' Day in America was on Saturday, November 11. "Veteran's Day (observed)" was also on the calendar; it was Friday, November 10.
