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.

A vacation or holiday is a leave of absence from a regular occupation, or 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 guide book or travel guide is "a book of information about a place designed for the use of visitors or tourists".
