Constitution Day is observed in Ireland every December 29, commemorating the day in 1937 when the current Constitution of Ireland came into force. This constitution serves as a fundamental law that guarantees certain rights, establishes a bicameral parliament, and outlines the separation of powers and judicial review. The celebration marks the anniversary of the adoption of the constitution, which followed a national plebiscite on July 1, 1937, and replaced the first constitution adopted in 1922, deemed controversial by many. Although Constitution Day is significant, it is not a public holiday, and many banks and government offices are already closed for the upcoming New Year’s Eve celebrations, providing people with an extended holiday period.
