Hangul Day, celebrated annually on October 9th in South Korea, commemorates the creation and proclamation of the Korean alphabet, Hangul. Introduced in 1443 by King Sejong the Great, Hangul was designed to improve literacy by providing an easy-to-learn writing system for the Korean language. Its simple and logical structure has played a vital role in preserving Korea’s linguistic and cultural identity. Today, Hangul Day not only honors this remarkable achievement but also promotes pride in the unique heritage of the Korean people. It is a day to appreciate the accessibility and beauty of Hangul.
