Holidays are the days an employee is entitled to abstain from working for his employer. Holidays, as far as work goes, come in many forms; there are mandatory holidays, national holidays, religion-specific holidays, as well as leaves.

Depending on the country and the job, these holidays may vary. For example, a common holiday is the first day of the year; however that does not apply to everyone as some people still need to work on that day (fe police officers, firefighters, telecommunication technicians). It should be highlighted, there is a bare minimum of holidays constituted that employers cannot ignore as they will face penalties.

National holidays, as well as religious holidays, depend on the country. For example, in Greece there is a national holiday on the 25^th of March, in remembrance of the revolt against the Ottoman Empire. While in Sweden, the 6^th of June is considered a national holiday in remembrance ofthe end of the Danish-ruled Kalmar Union. Other holidays include paid leaves, where the employee requests for some time-off on his own, maternity leaves, applicable to women that have recently been in labour, sick leaves, for unexpected events where the employee cannot go to work due to medical reasons, and finally (depending on the country) some weekdays that you do not work (usually Saturdays and Sundays).
