Gwangbokjeol takes place on August 15, 2019. Gwangbokjeol, (literally "Restoration of Light Day") is one of the Public holidays in South Korea. It commemorates Victory over Japan Day, which liberated Korea from colonial rule. The South Korean government was created three years later, on August 15, 1948, when Syngman Rhee was sworn in as the first President of South Korea and Gwangbokjeol was officially designated a public holiday on October 1, 1949.
Many activities and events happen during the day, including an official ceremony with the president in attendance that takes place at the Independence Hall of Korea in Cheonan or at the Sejong Center for the Performing Arts. All buildings and homes are encouraged to display the national flag Taegukki. Not only are most public museums and places are open free of charge to the descendents of independence activists on the holiday, but they can also travel on both public transport and intercity trains for free.
