A holiday is a day set aside by custom or by law on which normal activities, especially business or work, are suspended or reduced. Generally holidays are intended to allow individuals to celebrate or commemorate an event or tradition of cultural or religious significance. Holidays may be designated by governments, religious institutions, or other groups or organizations. The degree to which normal activities are reduced by a holiday may depend on local laws, customs, the type of job being held or even personal choices.
