Constitution Day: A Public Holiday?
Constitution Day is an official public holiday in Thailand, with government offices, schools, banks, and most businesses closed as the nation commemorates the adoption of its first constitution and honors its political development.

Constitution Day
Constitution Day, observed on December 10, marks a significant milestone in Thailand's political history. On this day in 1932, King Prajadhipok (Rama VII) granted the country its first permanent constitution, transforming Thailand from an absolute monarchy into a constitutional monarchy. This change followed the peaceful revolution led by the People's Party, which sought to introduce democratic governance while maintaining the monarchy as a respected national institution.
The adoption of the constitution marked the beginning of Thailand's journey toward democratic rule, though the country has experienced multiple constitutional changes and political transitions since then. Constitution Day serves as a reminder of the nation's ongoing efforts to balance monarchy, democracy, and the rule of law. The day honors both the historical significance of the 1932 event and the continuing importance of constitutional governance in shaping Thailand's political system.
