October 9 is Hangul Day (한글날), the celebration of the promulgation of the Korean alphabet Hangul (한글) by King Sejong the Great in 1446. Not a legal holiday in South Korea — not since 1991 — but everyone marks the day as special.
As you can see, Google Korea featured Hangul letters forming its logo on its home page. Ain’t that cool?
The alphabetic system used for writing the Korean language consists of 24 letters, including 14 consonant and 10 vowel symbols. Its “inventor” King Sejong is supposed to have said that even a fool can learn the hangeul alphabet in ten minutes. It’s that simple!
Trivia: North Korea celebrates its Chosŏn’gŭl Day (조선글날) on January 15, in line with the lunar calendar that was in use in the 15th century.
