Korea’s October holidays 2026: Foundation Day weekend and Hangeul Day
Practical 2026 guide for English-speaking visitors: National Foundation Day Sat 3 Oct (observed / substitute Mon 5 Oct) and Hangeul Day Fri 9 Oct — two long-weekend windows ≠ Chuseok, what usually closes vs stays open, transit tips without invented schedules, Seoul hub links, and a foliage stub flag.

Not Chuseok — start here
Korea’s early–mid October 2026 holidays are two shorter public-holiday windows, not another Chuseok-scale hometown migration.
Do not reuse Chuseok packing advice wholesale. Expect lighter nationwide exodus than late September, with the usual public-holiday pattern: banks and government offices closed, while many tourist sites, department stores, and amusement facilities stay open (Visit Korea FAQ — always verify the venue). Intercity trains and buses can still get busy around long weekends — book early, but you usually do not need a Chuseok-level “stay put or miss KTX” mindset.
If you just finished Chuseok travel, treat this page as the next calendar bridge, not a sequel with the same crowds.
What these holidays are (short version)
National Foundation Day (개천절, Gaecheonjeol) commemorates the legendary founding of the Korean nation. Visit Korea notes simple ceremonies at a few historic sites (for example Chamseongdan on Ganghwado and related Dangun shrines). Treat those as optional color, not a must-do itinerary.
Hangeul Day (한글날) marks the proclamation of Korea’s alphabet in 1446 (*Hunminjeongeum*). Expect cultural programming at some museums and libraries — hours still vary by venue.
You do not need a deep history lecture to travel well. Treat both as ordinary public holidays with long-weekend energy.
