2026 Korea Public Holidays: The Ultimate Guide from July to December
If you’re mapping out Korea public holidays for the back half of 2026, here’s a fun fact most Koreans don’t even know: until a few months ago, South Korea hadn’t had a real Constitution Day holiday since 2007. For 18 years, July 17 was just… a date. People went to work. Kids went to school. The country quietly ignored the day its own constitution was signed.
That changes in 2026 — and the reason why is worth knowing.
The holiday was stripped from the calendar in 2008, a casualty of a government push to reduce public holidays and boost productivity. For nearly two decades, July 17 was a date most Koreans had to actively remind themselves meant anything at all.
Then came December 3, 2024. A short-lived emergency martial law declaration — quickly overturned — sent shockwaves through Korean society and reignited a public conversation about constitutional values, rule of law, and what it actually means to protect democracy. In that atmosphere, quietly skipping the day the constitution was signed started to feel like a statement no one had consciously made.
President Lee Jae-myung, in his Constitution Day address last year, called for the day to become “an occasion to reflect on the spirit of popular sovereignty.” Legislation to restore it as a public holiday passed the National Assembly in late June 2026. After 18 years, July 17 is a day off again — and this time, people know why.

July 17: Constitution Day Returns After 18 Years
Constitution Day (제헌절) commemorates the day Korea’s constitution was promulgated back in 1948. It used to be one of Korea’s five major national holidays — until 2008, when the government quietly demoted it to a regular working day to boost productivity. Yes, really. Korea cut a national holiday for efficiency reasons. It’s the headline addition to the Korea Public Holidays July to December 2026 calendar this year.
Fast forward to 2026: the National Assembly passed a bill in January reinstating Constitution Day as an official paid holiday, it was signed into law in February, and it officially took effect on May 11, 2026. July 17 this year is the first time in 18 years that Constitution Day actually means a day off.
Because this is the first year back, expect some confusion. Some smaller businesses and offices may not have updated their calendars yet, so don’t be shocked if a few things operate on a normal schedule. Government offices, banks, and large corporations will be closed.
Falling on a Friday in 2026, July 17 sets up a long weekend without needing a substitute holiday — good news if you’re planning a short domestic trip or just want an extra day to explore Seoul without the usual weekday crowds.
August 15: Liberation Day (Gwangbokjeol) — Plus a Bonus Monday
Liberation Day (광복절) marks Korea’s liberation from Japanese colonial rule in 1945 — one of the most historically significant dates on the entire calendar. Expect a ceremony at Gwanghwamun Square, flags on display across the city, and a noticeably more solemn tone than your average Korean holiday.
Here’s the part that actually affects your itinerary: August 15 falls on a Saturday in 2026, which would normally mean the holiday gets “absorbed” into the weekend and you lose the day off. But Korea’s substitute holiday system (대체공휴일) kicks in, pushing an extra day off to the following Monday, August 17.
Net result: a tidy three-day weekend right in the middle of peak summer travel season. Book accommodations and KTX tickets early — domestic destinations like Busan and Jeju get booked out fast around this stretch.
September 24–26: Chuseok, Korea’s Biggest Holiday
If you only remember one holiday from this entire guide, make it this one. Chuseok (추석) — often translated as “Korean Thanksgiving” — is the single biggest travel event on the Korean calendar, full stop. Koreans call the mass movement of people returning to their hometowns “민족대이동,” which translates to something like “the great migration of the nation.” It is not an exaggeration. This is exactly the kind of stretch this Korea Public Holidays July to December 2026 guide exists for.
In 2026, Chuseok runs Thursday, September 24 through Saturday, September 26, and because it naturally rolls into Sunday, you get a full four-day weekend without any substitute-holiday math required.
What this means if you’re visiting Korea during this window:
- Transportation gets brutal.
KTX trains and intercity buses sell out, often weeks in advance. If you need to travel between cities during Chuseok, book the moment tickets open. - Many small restaurants and shops close.
Small restaurants may close but major attractions, palaces, and chain stores generally stay open. - The palaces actually lean into it.
Gyeongbokgung and other royal palaces typically run special Chuseok programs — traditional games, hanbok events, folk performances — making this one of the best weeks to visit a palace despite (or because of) the holiday.
If your trip overlaps with Chuseok, build in flexibility. This isn’t the week to plan a tight, multi-city itinerary.
October 3: National Foundation Day
October 3 commemorates the legendary founding of Korea by Dangun in 2333 BCE. The myth behind it: Hwanung, son of the heavenly ruler, descended to a Korean mountain wanting to live among humans. A bear and a tiger both prayed to become human, and Hwanung told them to survive 100 days in a cave eating only garlic and mugwort. The tiger gave up early; the bear endured and was transformed into a woman, Ungnyeo. She and Hwanung had a son — Dangun — who grew up to found Gojoseon, Korea’s first kingdom. It’s less verifiable history and more the founding myth every Korean grows up hearing. In 2026 it falls on a Saturday, which triggers the substitute holiday system again — you get Monday, October 5 off instead.
Here’s the part actually worth planning around: attach a single day of annual leave to this weekend and Oct 3–5 turns into four straight days off. Push further — take Oct 6, 7, and 8 as leave — and it bridges directly into Hangul Day’s Oct 9–11 stretch: three vacation days spent, nine days gained. Koreans call this kind of calculated bridge a “황금연휴” (golden holiday), and it’s a real, widely-used strategy — people lock in this exact leave window months in advance, so don’t expect to book it last-minute yourself.
What this means if you’re visiting: everyone in Korea is planning around this window too. Domestic flights and KTX tickets for early October sell out fast, and hotel prices in popular spots like Jeju, Busan, and Gyeongju climb accordingly. Book well ahead if you want in on that golden-week energy — or flip the logic and treat this exact week as the one to skip those routes, since Seoul itself tends to feel a little quieter and cheaper while everyone else has left town.
October 9: Hangul Day
October 9, is a personal favorite to explain to visitors because it’s so specifically Korean: it celebrates the creation of the Korean alphabet by King Sejong the Great in 1446. Before Hangul, Korean was written using Chinese characters, accessible only to the educated elite. Hangul was designed to be learnable by anyone in days, not years — a genuinely radical idea for its time. If you’re in Seoul, the National Hangul Museum near National Museum of Korea runs special exhibitions around this date.
In 2026, Hangul Day falls on a Friday, giving you a clean three-day weekend without needing a substitute day.
If you’re in Seoul around this date, swing by Gwanghwamun Plaza — the King Sejong statue usually gets a little extra attention that week, sometimes with small exhibitions or events tied to the anniversary. Compared to Chuseok’s mass exodus or the crowds around Foundation Day, Hangul Day is a genuinely quiet holiday to be in the city for: no traffic exodus, no packed palaces, just a normal three-day weekend with a better story behind it than most.
December 25 & December 31: Christmas and New Year’s Eve
Two final dates to close out the year — and both come with a myth worth busting.
Christmas Day is an official public holiday in Korea, which surprises a lot of visitors given how small the Christian-holiday culture can feel compared to back home. Here’s the reality: government offices, banks, and most large companies close, but Christmas in Korea functions more like a couples’ holiday than a family one — think Valentine’s Day energy. Cafes, restaurants, and shopping streets like Myeongdong stay very much open, often decorated and busy. Don’t expect a quiet, everything-shut holiday.
New Year’s Eve, December 31, is technically not an official public holiday — offices and most businesses operate as normal during the day. But culturally, it’s enormous. The centerpiece event is the Bosingak Bell-Ringing Ceremony in Jongno, where a historic bell is rung 33 times at midnight, drawing massive crowds in the heart of old Seoul. If you’re in the city, it’s one of the most atmospheric ways to ring in the new year — just expect serious crowd control and road closures around the area.
Practical Tips for Traveling During 2026
A few ground rules for navigating Korea Public Holidays July to December 2026 without losing a day of your trip to closures or fully booked KTX trains:
- Book Chuseok travel early — like, now. September 24–26 will be the single hardest stretch of the year to move between Korean cities. If your trip overlaps with it, lock in transportation first and build the rest of your itinerary around it.
- Don’t assume “holiday” means “everything is closed.” Major attractions, palaces, and large retail stay open on almost every date in this guide. It’s mainly small, family-run businesses and government offices that close.
- Watch for Constitution Day confusion. Since July 17 is back as a holiday for the first time since 2007, double-check opening hours for smaller venues if you’re visiting around that date in its first year back.
- Substitute holidays are your friend. Whenever a holiday lands on a weekend, Korea’s 대체공휴일 system usually adds a weekday off instead — which is exactly how August and October each turn into three-day weekends in 2026.
- November is holiday-free — and that’s a genuine travel tip, not a gap in this guide. Fewer domestic crowds, easier bookings, comfortable fall weather.
That’s the complete rundown of Korea Public Holidays July to December 2026 — what they mean, when they fall, and how they’ll actually affect your trip. Combined with Part 1’s January-to-June lineup, you now have the full 2026 holiday calendar mapped out, start to finish.
