If you're planning a trip to South Korea in the second half of 2026, understanding the Korean public holiday calendar is essential — not just for timing your visit perfectly, but for avoiding sold-out flights, fully-booked accommodations, and packed tourist attractions. South Korea's 2026 second-half public holidays are exceptionally favorable: Constitution Day (제헌절, Jeheonjeol — July 17) is reinstated as a public holiday for the first time since 2008, delivering an automatic 3-day weekend on a Friday. The Chuseok (추석) harvest holiday falls on September 24–26, and with a savvy 3-day leave combination, creates a 9-day break — one of the longest in years. For international visitors, this means Korea will be buzzing with domestic travelers during these periods, making early booking of accommodation and transport absolutely critical. For those planning to work and travel in Korea, this guide explains exactly when the peaks hit and how to schedule around them. According to the official VisitKorea public holiday page and timeanddate.com, here is the complete 2026 Korea second-half public holiday rundown.

1. Overview of Korea's 2026 Second-Half Holidays
Constitution Day (제헌절) Returns — Friday, July 17
The biggest change to Korea's 2026 holiday calendar is the reinstatement of Constitution Day (제헌절, Jeheonjeol) as a public holiday. Originally designated as a national holiday in 1949 to celebrate the promulgation of the Republic of Korea's constitution, it was removed from the public holiday list in 2008 as part of a government efficiency drive. In May 2026, the National Assembly passed an amendment to reinstate it — making July 17 a red-letter day for the first time in 18 years. As confirmed by the official VisitKorea holidays page, July 17 falls on a Friday in 2026, creating an automatic 3-day weekend (Friday–Saturday–Sunday) at no leave cost. For international visitors, this is an ideal window for a short Korea trip — though Jeju Island, the East Sea coast, and popular mountain resorts will be busier than usual.
Full List of 2026 Second-Half Korea Public Holidays
According to official sources including VisitKorea, timeanddate.com, and the Korea Customs Service English portal, the confirmed public holidays for the second half of 2026 are as follows. In July, Constitution Day falls on Friday July 17. In August, Liberation Day (광복절, Gwangbokjeol) falls on Saturday August 15, with a substitute holiday on Monday August 17. In September, the Chuseok (추석) harvest holiday period runs Thursday September 24 through Saturday September 26, with a substitute holiday on Monday September 28. In October, National Foundation Day (개천절, Gaecheonjeol) falls on Saturday October 3, and Hangul Day (한글날, the holiday celebrating the Korean alphabet) falls on Friday October 9. November has no national holidays. In December, Christmas (크리스마스) falls on Thursday December 25. Note: April and November are the only months in 2026's full calendar with no public holidays whatsoever.
Why 2026's Second Half Is Exceptionally Favorable
What makes 2026's second-half holiday calendar stand out is the distribution of holidays across the working week. Constitution Day on a Friday, Hangul Day on a Friday, and Christmas on a Thursday all create automatic extended weekends or near-weekends with zero leave required. Chuseok falling Thursday–Saturday means that adding just 3 days of paid leave before it (Monday–Wednesday, September 21–23) creates a 9-consecutive-day break from Saturday September 20 to Sunday September 28 — one of the longest possible Chuseok windows in recent years. For workers and travelers alike, this is a genuinely rare alignment.

💡 Expedia bundles flights + hotels for Korea — perfect for planning a Chuseok or Hangul Day trip in one go!
Expedia and Trip.com allow you to bundle international flights into Korea with Seoul hotel stays, often at a discount versus booking separately. For the September Chuseok window, search "Incheon + Seoul hotel" on Expedia and filter by September 20–28 to compare package prices. Setting up a price alert now and booking when the price drops is the most cost-effective strategy. Klook is also excellent for pre-booking day tours, airport transfers, and popular attractions like Gyeongbokgung Palace before prices spike during the holidays.2. Month-by-Month Golden Holiday Breakdown
July — Constitution Day 3-Day Weekend (or 7 Days with Leave)
Friday July 17 (Constitution Day) gives anyone in Korea an automatic 3-day weekend — Friday through Sunday — without spending a single day of paid leave. For workers, adding July 14–16 (Tuesday through Thursday, 3 days of leave) extends this to a 7-consecutive-day break from Saturday July 11 to Friday July 17. This is Korea's peak summer season — Jeju Island, Gangwon Province, and the East Sea beaches will be in high demand. If you're visiting Korea specifically during this period, book accommodation and transport no later than early July, or ideally in June. For international visitors flying in for the long weekend, this is one of the best cost-effective summer windows to visit Korea before August peak prices kick in.
September — 9-Day Chuseok Break (with 3 Days Leave)
Chuseok (추석) — sometimes called Korean Thanksgiving — is the most important traditional holiday in the Korean calendar. Families travel across the country to gather, pay respects at ancestral graves, and share traditional food like songpyeon (송편, half-moon rice cakes). The 2026 Chuseok holiday runs Thursday September 24 through Saturday September 26, with a substitute holiday on Monday September 28 (since Chuseok's first day overlaps with National Foundation Day weekend). Adding 3 days of paid leave (Monday–Wednesday, September 21–23) creates an uninterrupted 9-day break from Saturday September 20 to Sunday September 28. This is an ideal window for a longer international trip to Korea — though note that domestic travel (KTX, express buses) and popular accommodations sell out weeks in advance during Chuseok. For foreign visitors, this is also a fascinating time to witness Korean family traditions — though many shops and restaurants in smaller cities may close during the 3-day core holiday period.

October to December — Hangul Day, Gaecheonjeol & Christmas
Hangul Day (한글날, October 9) celebrates the creation of the Korean alphabet (Hangeul, invented by King Sejong in 1443) and falls on a Friday in 2026, creating another automatic 3-day weekend. National Foundation Day (개천절, October 3) falls on a Saturday — its substitute holiday possibility should be confirmed on official sources. Adding 3 days of paid leave (October 6–8, Tuesday–Thursday) could link Gaecheonjeol and Hangul Day into a 9-day October mega-break. Christmas (December 25) falls on Thursday — adding just 1 day of leave on Friday December 26 creates a 4-day break from Thursday through Sunday, perfect for a Seoul winter getaway. Looking ahead, combining Christmas with New Year's Day (January 1, 2027, also a Thursday) by using December 28–31 leave creates an extraordinary year-end holiday stretch.
3. Leave Planning — 4-Step Strategy
Step 1 — Prioritize Leave Around Chuseok
If you're working in Korea and have limited paid leave remaining in 2026, the most efficient allocation is to concentrate around the Chuseok period. Using 3 days of leave on Monday–Wednesday (September 21–23) converts the 3-day Chuseok holiday into a full 9-day break — the best leave-to-holiday ratio of the entire second half. After that, July 14–16 (3 days) adds 4 days to the Constitution Day 3-day weekend, giving a 7-day stretch. Hangul Day (October 9, Friday) requires zero leave for a 3-day weekend. Christmas (December 25, Thursday) only needs 1 day of leave for a 4-day break. This hierarchy — Chuseok → Constitution Day → Christmas — is the optimal leave distribution for 2026's second half.
Step 2 — Book Chuseok Flights & Accommodation Now
Chuseok is the busiest travel period in Korea — flights, KTX trains, and express buses from and to major cities sell out weeks or months in advance. The current booking window (June 2026) is the ideal time to secure Chuseok travel. International flights to/from Korea during the September 20–28 period should ideally be booked now on Trip.com, Expedia, or directly through airlines. For domestic accommodation, Jeju Island, Busan, Gyeongju, and Gangwon Province are most popular during Chuseok. Search these destinations on Agoda or Booking.com immediately and compare prices with free cancellation options where possible.
Step 3 — Pre-Book Korea Transport for Holiday Periods
KTX (Korea's high-speed rail) and intercity express buses are the two main options for getting around Korea during national holidays. KTX seats, especially KTX-Eum and KTX-Sancheon on popular routes (Seoul–Busan, Seoul–Gwangju, Seoul–Gyeongju), sell out 1 month in advance during Chuseok. International visitors can book KTX tickets in English via Trip.com, which accepts international credit cards. Express buses for Chuseok open pre-booking 30 days before departure — for September 21–23 departures, that means late August. Set a reminder now. Payment at Korean bus terminals typically accepts both cash (KRW) and major credit cards.
Step 4 — Use Google Calendar to Block Your Holidays Now
The single most practical tip for anyone living or working in Korea is to add all 2026 second-half public holidays to their digital calendar immediately. This is especially important for Constitution Day (July 17) — having been off the public holiday list since 2008, it may not appear on older calendar apps or printed diaries. On Google Calendar, subscribe to the "South Korea Holidays" calendar under "Other Calendars" to automatically sync all official holidays. For workplace leave planning, having the dates pre-blocked well in advance is the clearest way to secure priority approval for Chuseok and other peak days before colleagues claim the same slots.

💡 Klook lets you pre-book Korea's top attractions before holiday crowds arrive — skip the queues during Chuseok!
During Korean national holidays, queues at top attractions like Gyeongbokgung Palace, Everland, Lotte World, and Nami Island can stretch for hours.

Jeju Island — Best for July Constitution Day Weekend
For the July Constitution Day 3-day weekend, Jeju Island is the top domestic destination in Korea. July Jeju offers emerald seas, lush Hallasan (한라산) mountain greenery, and iconic natural landmarks like Seongsan Ilchulbong (sunrise peak), Manjanggul lava tube, and Hyeopjae Beach. Jeju is a visa-free destination for most nationalities visiting Korea, making it especially accessible for international travelers on short notice. Flights from Seoul Gimpo Airport to Jeju take approximately 1 hour, with domestic fares starting from around 50,000–80,000 KRW (~$37–59 USD) one way if booked in advance. Search Jeju accommodation on Agoda or Booking.com now — July Constitution Day weekend inventory fills quickly.
Gyeongju & East Sea Coast — Best for Chuseok 9-Day Break
For the 9-day Chuseok break in September, the east coast corridor — Sokcho, Gangneung, and Yangyang in Gangwon Province — is one of Korea's most popular domestic travel routes. September temperatures are ideal: post-summer heat, pre-autumn chill, with the first hints of fall foliage beginning. Gyeongju (경주), Korea's ancient Silla Dynasty capital, is another excellent Chuseok destination — the city's royal tombs, Bulguksa Temple (a UNESCO World Heritage Site), and Cheomseongdae observatory all take on a special atmosphere during the harvest holiday season. From Seoul, Gyeongju is approximately 2 hours by KTX (alight at Singyeongju Station). Accommodation in Gyeongju starts from around 60,000 KRW (~$45 USD) per night during Chuseok.
Seoul & Short-Haul International — Best for October Hangul Day & Christmas
October's Hangul Day 3-day weekend (or potential 9-day break) is ideal for short-haul international travel from Korea — Japan, Taiwan, Thailand, and Vietnam are all within 2–6 hours. October is not peak season for most Asian destinations, keeping airfares relatively affordable. Trip.com and Expedia are the most reliable platforms for comparing October Asia flight options. For Christmas, a Seoul city winter holiday — including Everland's Christmas light festival and the Myeongdong holiday shopping district — is a classic experience. December 25–28 (4 days with 1 day leave) is just enough for a Seoul city break or a Gangwon ski resort trip. Search "Gangwon ski resort" on Klook for ski package deals available from December.
5. Leave vs. Holiday Efficiency Comparison
| Holiday Period | Leave Used | Total Days Off |
|---|---|---|
| Constitution Day (July 17) | 0 days leave | 3 days (Fri–Sun) |
| Constitution Day Extended | 3 days leave | 7 consecutive days |
| Chuseok Basic | 0 days leave | 3 days (Chuseok holiday) |
| Chuseok Golden Break | 3 days leave | 9 consecutive days |
| Christmas Break | 1 day leave | 4 days (Thu–Sun) |
6. Top 5 Tips for International Visitors During Korean Holidays
Tip 1: Focus Leave on Chuseok — Best ROI by Far
Of all the second-half holiday opportunities in 2026, adding just 3 days of leave to the Chuseok period gives you the best return: 3 leave days become 9 consecutive days off. For international visitors planning a longer Korea trip, timing your visit to include September 20–28 gives maximum flexibility and the authentic experience of witnessing Korea's most important family holiday in full swing.
Tip 2: Constitution Day Is FREE — No Leave Required
July 17 (Friday) is a gift — automatic 3-day weekend with zero leave required. For international visitors, the July Constitution Day weekend is a great budget-conscious window to visit Korea before August peak prices. Jeju and the East Sea coast are busy, but less so than full August. Book accommodation 4–6 weeks in advance for the best rates.
Tip 3: One Day's Leave at Christmas = 4-Day Seoul Winter Break
Christmas (Thursday, December 25) + just 1 day leave on Friday December 26 = a 4-day long weekend to experience Seoul's magical winter atmosphere. From ice skating at Seoul City Hall Plaza to Everland's Christmas light displays and Myeongdong holiday shopping, December in Seoul is a genuinely festive experience. Book Seoul accommodation at least 6–8 weeks ahead for December 25–28.
Tip 4: Book Flights 2–3 Months Ahead for Korea Holiday Windows
International flights to Incheon Airport (ICN) see significant price spikes 3–6 weeks before major Korean holidays. The current timing (June 2026) is the sweet spot for booking Chuseok (September) travel at the best prices. Search on Expedia, Trip.com, or directly on airline websites. For Chuseok, flexible-date searches around September 18–30 often reveal lower fares than fixed peak dates.
Tip 5: Add South Korea Holidays to Google Calendar Now
On Google Calendar, go to "Other Calendars" → "Browse Calendars of Interest" → "South Korea" to automatically sync all 2026 public holidays, including the newly reinstated Constitution Day. This is the simplest way to ensure you don't accidentally schedule important meetings or overlapping travel during Korean holiday peak periods — especially important for expats, remote workers, and business travelers in Korea.

Q1. Why is Constitution Day back as a public holiday in Korea in 2026?
A. Constitution Day (제헌절, July 17) was removed from Korea's public holiday list in 2008 as part of a government reform. In May 2026, the National Assembly passed an amendment reinstating it, making it a public holiday again for the first time in 18 years. In 2026, it falls on a Friday — automatically creating a 3-day Fri–Sat–Sun weekend.
Q2. How can I get a 9-day Chuseok break in 2026?
A. The Chuseok holiday runs Thursday September 24 – Saturday September 26, with a substitute holiday on Monday September 28. Adding 3 days of paid leave on Monday–Wednesday, September 21–23, connects the weekend of September 20–21 through to Sunday September 28 — creating a 9-consecutive-day break for just 3 days of annual leave.
Q3. How can I create a long holiday break at Christmas 2026?
A. Christmas falls on Thursday, December 25, 2026. Taking just 1 day of leave on Friday December 26 creates a 4-day break (Thursday through Sunday, December 25–28). For an extended year-end break, combining this with New Year's Day 2027 (January 1, also a Thursday) by using December 28–31 leave creates a very long stretch running from Christmas through the New Year.
Q4. When does the Hangul Day 2026 holiday fall?
A. Hangul Day (한글날) — the holiday celebrating the Korean alphabet created by King Sejong in 1443 — falls on Friday, October 9, 2026. This creates an automatic 3-day Fri–Sat–Sun weekend at no leave cost. Combined with National Foundation Day on October 3 (Saturday), adding leave October 6–8 can potentially create a 9-day October break; check the official VisitKorea holiday calendar for the most current substitute holiday confirmation.
