Korean Alphabet Day (North Korea)

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, the Korean alphabet, by the 15th-century 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.

North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and borders China and Russia to the north at the Yalu (Amnok) and Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone (DMZ). The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like South Korea, claims to be the sole legitimate government of the entire peninsula and adjacent islands. Pyongyang is the capital and largest city.
