The Korean Alphabet Day, known as Hangeul Day (Korean: 한글날) in South Korea, and Chosŏn'gŭl Day (Korean: 조선글날) in North Korea, is a national Korean commemorative day marking the invention and proclamation of Hangul (한글), the Korean alphabet, by the 15th-century Korean king Sejong the Great. It is observed on October 9 in South Korea and January 15th in North Korea. Excluding the years 1990 to 2012, when the government maximized business days to expedite industrial growth, Hangul Day has been a national holiday in South Korea since 1970.[1]
