In 2026, Hangeul Day falls on Friday, October 9. Together with Saturday the 10th and Sunday the 11th, it creates a three-day holiday weekend from October 9 (Fri) to October 11 (Sun). Because Hangeul Day is an official national holiday that falls directly on a Friday, no substitute holiday applies. The week prior, National Foundation Day (Gaecheonjeol) on October 3 fell on a Saturday, granting Monday the 5th as an alternative public holiday. This lines up back-to-back three-day weekends across the first two weeks of October.
This year also holds deep historical meaning. It marks the 580th anniversary of the promulgation of Hunminjeongeum and the centennial (100th anniversary) of Hangeul Day, which originated in 1926 as "Gagyanal." As a result, municipal celebrations nationwide will be substantially larger than usual, launching on the first day of the holiday weekend. Below is a practical guide on how to divide your three days, where peak congestion will hit, and whether key Hangeul-related historic sites are open to visitors.
| Date | Day | Character | Travel Tips |
|---|---|---|---|
| Oct 9 | Fri | Hangeul Day | Most commemorative events kick off today. Outbound morning traffic will be heavy. |
| Oct 10 | Sat | Mid-Holiday | The most relaxed day of the weekend. Best night for an overnight stay if planning a 2-day getaway. |
| Oct 11 | Sun | Return Day | Inbound traffic toward the Seoul Metropolitan Area gets congested by late afternoon. Stick to nearby spots. |
The second week of October is prime season for silver grass and autumn blooms rather than vibrant foliage. Fall colors in high mountain peaks like Seoraksan are only just beginning, while lower elevations remain green. Seoraksan recorded its first autumn leaves around Daecheongbong Peak on September 28 (covering about 20% of the mountain), with the Korea Forest Service predicting peak colors around October 20. If heading to Seoraksan over the holiday, keep in mind that seasonal traffic controls (October 3 to November 8) may restrict private vehicles entering Sogongwon. Plan on parking at the free Seorak-dong Zones B and C lots and catching the shuttle (Seoraksan). For silver grass spots, see Silver Grass and Pink Muhly Spots Nationwide, and check Autumn Foliage Spots for foliage timelines.
To mark the centennial of Hangeul Day, local governments have scheduled major celebrations across the three-day break. Below are events with confirmed dates and schedules announced by organizers.
| Event | Dates | Location | Highlights |
|---|---|---|---|
| 2026 Sejong Hangeul Festival | Oct 9–11 | Sejong Central Park & Sejong Lake Park | Black Eagles airshow at 12:00 PM on Oct 9; 2,000-drone show at 8:40 PM. 600 pyrotechnic drones on the night of Oct 10. Closing concert at 6:00 PM on Oct 11. |
| Hangeul Hanmadang & Gwanghwamun Eve Celebration | Oct 6–8 (Eve: Oct 8, 7:00 PM) | Gwanghwamun Square, Seoul | Around 20 performances and workshops. The eve gala features the lighting of 100 art installations alongside performances by At Heart and Broccoli, You Too?. |

| Mindungsan Singing Contest | Oct 9–10 | Mindungsan Mountain area, Jeongseon | Part of the Mindungsan Silver Grass Festival (Sep 18–Nov 8). |
Sejong City takes its very name from King Sejong the Great. With large-scale evening shows planned, parking in Sejong Special Self-Governing City will be most challenging after dusk. Yeoju's festivities are geared toward families with toddlers and primary school children, making a morning visit the smoothest choice. In Seoul, cultural programs will take over Gwanghwamun Square as part of the Ministry of Culture, Sports and Tourism's "2026 Hangeul Week" (October 6–17). It is easy to take in the eve celebration at Gwanghwamun on the night before the holiday (October 8) before heading down toward Sejong the following day. For detailed event timetables and parking tips, see the Sejong Hangeul Festival Guide.

| Destination | Region | 2026 Status | Visiting Info |

The most common wasted trip happens at the National Hangeul Museum. While conveniently located right next to the National Museum of Korea in Yongsan and frequently featured on holiday lists, it remains closed for reconstruction following a fire, aiming to reopen in October 2028. You cannot tour commemorative exhibitions inside the building this year.
Yeongneung is the joint burial mound of King Sejong, the 4th monarch of the Joseon Dynasty, and Queen Soheon. October 9 falls on a Friday, so regular visiting hours apply, with cultural festivities taking place across the tomb grounds on the same day. Located in eastern Gyeonggi Province, it is just over an hour's drive from Seoul, making for a manageable day trip.
Day Trip with Kids (Seoul Metropolitan Area) — Morning at the Yeoju King Sejong's Tomb cultural festival → Lunch → Afternoon walk along the royal tomb forest trails. The site is regularly closed on Mondays, but remains open on all three holiday dates (Fri, Sat, Sun).
Day Trip for Silver Grass — Early morning hike up Mindungsan in Jeongseon on the first day, followed by enjoying the Mindungsan Singing Contest. Hiking routes and parking details can be found in the Jeongseon Mindungsan Hiking Guide.
2-Day Trip: Chungcheong Region — Day 1: Daytime workshops and nighttime drone show at the Sejong Hangeul Festival → Overnight in Sejong → Day 2: Head to Asan in Chungcheongnam-do for a walk along the Gokgyocheon Stream embankment. Ginkgo leaves reach peak color between late October and early November, so trees will likely still show green during this weekend. Check foliage timelines in Top Ginkgo Spots.
2-Day Trip: Mountain Concert & Silver Grass in Yeongnam — On October 3 (National Foundation Day), the weekend prior to Hangeul Day, the 16th Ulju Odyssey Mountain Concert takes place at Ganwoljae in Ulju. While there is no concert over Hangeul Day weekend, the silver grass fields of Ganwoljae remain at their prime.
Even outside of Hangeul-themed events, many major autumn festivals hit their stride or conclude over this three-day weekend. Because it is the final weekend for several popular gatherings, expect crowds and verify dates in advance.

As of October 6, the Korea Expressway Corporation has not yet released its formal holiday traffic forecast. However, for a Friday-to-Sunday long weekend, traffic typically bottlenecks outbound on Friday morning and inbound toward Seoul on Sunday afternoon. Conversely, Saturday morning and late Friday afternoon tend to see smoother traffic flows.
The second week of October offers crisp, comfortable walking conditions during the day, but substantial diurnal temperature drops in the mornings and evenings. At silver grass ridges around 1,000 meters above sea level, temperatures drop sharply and winds are strong compared to flat ground. Check short-term forecasts from the Korea Meteorological Administration before heading out.
Is there a substitute holiday for Hangeul Day in 2026? No. Hangeul Day (October 9) falls on a Friday, so it does not overlap with the weekend. Instead, it naturally forms a three-day weekend running Friday through Sunday.
Can I visit the National Hangeul Museum? No, it is closed during the 2026 Hangeul Day holiday. It remains shut for fire restoration and expansion, targeting an October 2028 reopening.
Is King Sejong's Tomb (Yeongneung) open on Hangeul Day? Yes. Regular closures are on Mondays, and October 9 is a Friday. Cultural events celebrating Hangeul Day will be held across the grounds on the same day.
Which Hangeul Day event is best for kids? The Yeoju King Sejong's Tomb Hangeul Day Cultural Event is specifically designed for families with toddlers and elementary school children. The daytime program at the Sejong Hangeul Festival also heavily features hands-on craft and activity booths.
Can I see fall foliage during the Hangeul Day weekend? Autumn colors are just beginning on high mountain ridges, but it is too early for city parks and lower plains. Silver grass is a much more reliable spectacle during this weekend. Check regional foliage timing in Autumn Foliage Spots.
What events are taking place at Gwanghwamun over the weekend? Gwanghwamun Square hosts the Hangeul Hanmadang (Oct 6–8), the Eve Celebration (Oct 8, 7:00 PM), the nightly media facade "Twenty-Four, Universe" (Oct 8–11, 8:00–11:00 PM), and the Seoul Metropolitan Government's "Seoul Bustles with Hangeul" event on October 9.
