A vacation or holiday is a specific trip or journey, usually for the purpose of recreation or tourism. People often take a vacation during specific holiday observances, or for specific festivals or celebrations. Vacations are often spent with friends or family.A person may take a longer break from work, such as a sabbatical, gap year, or career break.The concept of taking a vacation is a recent invention, and has developed through the last two centuries. Historically, the idea of travel for recreation was a luxury that only wealthy people could afford (see Grand Tour). In the Puritan culture of early America, taking a break from work for reasons other than weekly observance of the Sabbath was frowned upon. However, the modern concept of vacation was led by a later religious movement encouraging spiritual retreat and recreation. The notion of breaking from work periodically took root among the middle and working class.EtymologyIn the United Kingdom, vacation once specifically referred to the long summer break taken by the law courts and then later the term was applied to universities. The custom was introduced by William the Conqueror from Normandy where it facilitated the grape harvest. In the past, many upper-class families moved to a summer home for part of the year, leaving their usual home vacant.
