About Hangul Proclamation Day
Hangeul Day, represented in the portable corpus as Hangul Proclamation Day, is observed in the Republic of Korea on 9 October.
The observance began in 1926 as Gagya Day, organized by the Korean Language Research Society, and was renamed Hangeul Day in 1928.
Why Hangul Proclamation Day matters
The day commemorates Hangeul and the publication tradition associated with Hunminjeongeum.
The modern October 9 date derives from dating evidence in the Hunminjeongeum Haerye, and the day is now a Korean national day and public holiday.
History of Hangul Proclamation Day
On 4 November 1926, the Korean Language Research Society held the first Gagya Day celebration, using the lunar ninth month’s 29th day converted to the solar calendar.
The name changed to Hangeul Day in 1928; the date later moved through October 29 and October 28 before being fixed at October 9.
The National Hangeul Museum records later status changes: public-holiday recognition after liberation, removal from the public-holiday calendar in 1990, elevation to a national day in 2005, and restoration as a public holiday from 2013.
