Hangeul Day commemorates the proclamation of the Korean alphabet, Hangeul, by King Sejong the Great in 1446. The original document announcing the alphabet, known as Hunminjeongeum, was created to provide an accessible writing system for the Korean people.

Hangeul is widely regarded as one of the most scientifically designed alphabets in the world. Its structure reflects phonetic principles, making it logical and easy to learn. The creation of Hangeul played a crucial role in improving literacy and strengthening national identity.

Hangeul Day is designated as an official public holiday in Korea. Schools, banks, and government offices are closed. Cultural institutions and educational organizations often hold exhibitions, academic forums, and language-related events to highlight the historical and global significance of the Korean script.

For international readers, Hangeul Day represents a rare example of a national holiday dedicated to a writing system. It underscores the importance of language in shaping cultural heritage and modern national identity.
