Constitution Day

Constitution Day, known in South Korea as Jeheonjeol (제헌절), is observed each year on July 17 to commemorate the promulgation of the Constitution of the Republic of Korea on July 17, 1948. The Constitution was adopted by the Constituent National Assembly during the formative period following the end of Japanese colonial rule and established the Republic of Korea as a democratic republic founded on popular sovereignty, representative government, fundamental rights, and the separation of powers. In 2026, Constitution Day will fall on Friday, July 17.

The date became a national commemorative occasion in 1949 and was designated a public holiday in the early years of the republic. It ceased to be a paid public holiday in 2008 as part of changes associated with the five-day working week, although it remains an official national observance and retains considerable constitutional and historical importance. Jeheonjeol is one of Korea’s major national commemorative days, alongside Independence Movement Day, Arbor Day, Children’s Day, Memorial Day, Liberation Day, National Foundation Day, and Hangeul Day. Its modern significance centers on reflecting on constitutional democracy, civil liberties, the rule of law, and the continuing development of the Korean state.

Constitution Day is generally marked through official ceremonies hosted by government institutions, the National Assembly, courts, schools, and civic organizations. Events may include the reading of constitutional principles, speeches by public officials, academic forums, exhibitions, and educational programs explaining the Constitution and the history of Korea’s democratic institutions. The national flag, Taegeukgi, is displayed in public spaces and at government buildings, and broadcasters and newspapers often feature historical programs or commentary on constitutional rights and civic responsibilities.

Unlike Lunar New Year or Chuseok, Jeheonjeol has no distinctive traditional menu, family ritual, or nationwide folk celebration. Many people observe it quietly through civic education, visits to museums or historical sites, and discussion of democratic values. Suitable Korean greetings include “제헌절을 기념합니다” (I commemorate Constitution Day) and “대한민국 헌법의 뜻을 되새기는 뜻깊은 하루 되세요” (May you have a meaningful day reflecting on the spirit of the Constitution of the Republic of Korea). Because July 17 is not currently a public holiday, ordinary business and school schedules generally continue, although official commemorative activities may be held.
