A holiday is any day when people lay aside their ordinary duties and cares. The word came from Old English. At first, holidays honored some holy events or persons. People in Great Britain and other countries speak of holidays as Americans speak of vacations.

Every nation has its special holidays. China observes New Year’s Day (January 1), May Day and National Day as legal (法定的)holidays , as it was on Oct.1,1949 that the People’s Republic of China was founded. The Chinese have long celebrated the Chinese lunar year. In the United States, congress has declared several days as legal holidays such as New Year’s Day (January 1), Martin Luther King, Jr.’s Birthday, Washington’s birthday, Thanksgiving Day and Christmas Day and so on. Some holidays celebrated special events in the development of a country, such as Greece’s Independence Day, Italy’s Liberation Day and India’s Independence Day.

In the United States, banks and schools usually close on a legal holiday. When such a holiday falls on Sunday, the following Monday is usually observed. Schools and organizations often observe days known as traditional holidays, although schools and business do not close then. Those holidays include Valentine’s Day and Halloween.
