What are the National Public Holidays in Indonesia in 2018?
Indonesia is the world's largest archipelago. Due to the country's huge size it contains a high degree of diversity in terms of religion and traditional belief systems. Although Indonesia has a Muslim-majority population, it is a secular democracy with a constitution that guarantees all Indonesian citizens the freedom of worship, each according to his or her own religion or belief (this system does not function perfectly in reality, however). Still, it means that Indonesia contains many (mostly religion-inspired) public holidays on which the nation's financial markets are closed.
The table below presents the national holidays of Indonesia - set by the government - for the year 2018 (trading holidays). We only present those holidays that affect weekdays. Dates of several holidays vary by year:
