Hangeul Day once had another name: Gagyanal. The day was introduced in 1926 to celebrate Korea's writing system, and its name and significance have evolved over a century.
The National Hangeul Museum's centennial exhibition '1926: Infinite Takeoff' traces that story. Its venue is the third-floor thematic gallery of the National Museum of Korean Contemporary History in Seoul, not the National Hangeul Museum building itself. Checking the venue carefully matters when planning a trip.
According to the organising museum's own detailed page, the exhibition runs October 2, 2026–February 9, 2027. Hours are 10 am–6 pm on Monday, Tuesday, Thursday, Friday and Sunday, and 10 am–9 pm on Wednesday and Saturday. Entry closes 30 minutes before closing. School groups of 20 or more students are instructed to book ahead.
Whether you read Hangeul fluently or have just started learning Korean, the history of its celebration adds a new layer to the letters you see across Seoul. Check closures and guided-tour availability before visiting.
