Under Law Number 7 of 2017 concerning General Elections, Polling Day for a general election or a regional election is a public holiday that is gazetted by the returning officer from the General Elections Commission. Under the Circular Letter (SE) of the Minister of Manpower, employees not required to work on that day are entitled to one day off in lieu or be given one day's pay.
In addition to the official holidays, many religious, historical, other traditional holidays, and even United Nations observances populate the calendar, as well as observances proclaimed by officials and lighter celebrations. These are often observed by businesses and schools as holidays.
