Countdown to Hangul Day

History & Origins of Hangul Day

Hangul Day (Korean Alphabet Day) in South Korea is celebrated on October 9th. It commemorates the historic proclamation of the native Korean alphabet, Hangul, by King Sejong the Great in October 1446. Prior to Hangul, Koreans used complex Chinese characters, which restricted literacy to the elite. King Sejong created the highly scientific, easy-to-learn alphabet explicitly to enable the common people to read and write easily.

How It Is Observed & Celebrated

Marked by major calligraphy competitions, academic conferences on linguistics at the King Sejong Statue in Gwanghwamun Plaza, museum open houses, and public performances celebrating Korean literature.
