A Complete Guide to Public Holidays in South Korea — Everything Foreigners Need to Know
Discover all South Korea public holidays — dates, meanings, lunar calendar holidays, Taegeukgi flag days, substitute holidays, and the difference between national days and public holidays. A must-read guide for foreigners visiting or living in Korea.
Introduction:
South Korea is a country where ancient tradition and modern culture blend seamlessly — and nowhere is this more visible than in its public holidays. From the centuries-old harvest festival of Chuseok to the nationally revered Independence Movement Day, Korean public holidays offer a fascinating window into the soul of the nation. Whether you are planning to visit, living as an expat, or simply curious about Korean culture, understanding these holidays will enrich your experience enormously. This comprehensive guide covers every official public holiday in South Korea, explains their cultural and historical significance, clarifies the differences between a national day (국경일) and a public holiday (공휴일), explains the lunar calendar system, and tells you exactly when to expect to see the iconic Taegeukgi — South Korea’s national flag — flying proudly from homes and government buildings.
What Is the Difference Between a National Day (국경일) and a Public Holiday (공휴일)?
This is one of the most commonly misunderstood aspects of the Korean holiday system, even among long-term residents. In South Korea, holidays are legally categorized into three distinct types, each with a different legal basis and purpose.
A National Celebration Day (국경일, Gukgyeongil) is a day designated to commemorate a particularly significant event in Korean national history — typically a founding, a liberation, or a major cultural achievement. These days are governed by The Law Concerning the National Celebration Days and carry an official, ceremonial character. There are currently five National Celebration Days: Independence Movement Day (March 1), Liberation Day (August 15), National Foundation Day (October 3), Constitution Day (July 17), and Hangul Day (October 9). All National Celebration Days are also flag-raising days, meaning citizens are strongly encouraged — and in many public spaces required — to display the Taegeukgi.
A Public Holiday (공휴일, Gonghyuil), on the other hand, is simply a legally designated day off from work and school. It is governed by the Regulations on Holidays of Public Agencies. A public holiday does not have to be a National Celebration Day. For example, Seollal (Korean New Year), Chuseok (Harvest Festival), and Christmas are all public holidays but are not National Celebration Days. Conversely, Constitution Day (July 17) is a National Celebration Day — and a flag-raising day — but it was removed from the list of days off in 2008, meaning businesses and schools are open on that day.
In short: all National Celebration Days are important, but not all of them are days off, and many popular holidays are days off without being National Celebration Days.
What Is the Lunar Calendar (음력) and Why Does It Matter?
The lunar calendar (음력, Eumllyeok) is a traditional calendar system that marks time based on the cycles of the moon. One lunar month begins with the new moon and lasts approximately 29–30 days, making a lunar year about 10–11 days shorter than the solar (Gregorian) year. To keep the lunar calendar aligned with the seasons, an extra “leap month” is occasionally added — a process that makes the system technically a lunisolar calendar.
Korea used the lunar calendar as its official calendar system for centuries, and it still plays a central role in traditional holidays, ancestral memorial rites (제사, jesa), and even birthday celebrations for older Koreans. Three of South Korea’s official public holidays — Seollal (Korean New Year), Buddha’s Birthday, and Chuseok (Harvest Festival) — are based on fixed dates in the lunar calendar. This means their corresponding Gregorian (solar) calendar dates shift every year, which is why they appear on different dates each year on the calendar you use at home.
How to Check the Gregorian Dates for Lunar Holidays:
- Seollal falls on the 1st day of the 1st lunar month
- Buddha’s Birthday falls on the 8th day of the 4th lunar month
- Chuseok falls on the 15th day of the 8th lunar month
To find out the exact solar calendar date for any given year, you can use dedicated Korean lunar-to-solar calendar converters available online. Reliable tools include the Korean Astronomy and Space Science Institute website (kasi.re.kr), and any major Korean portal such as Naver or Daum, which display the lunar date alongside the solar date on their calendar apps. The table below shows approximate solar dates for the near future.
Complete List of South Korea’s Public Holidays
🎉 January 1 — New Year’s Day (신정, Sinjeong)
January 1st is the Gregorian New Year, observed as a single public holiday. While South Koreans widely celebrate this day with countdown events and fireworks — particularly around Bosingak Bell in Seoul and Lotte World Tower — it is generally considered a quieter, less culturally significant holiday compared to the traditional Lunar New Year (Seollal). Shops, restaurants, and tourist attractions are typically open, though government offices and schools are closed.
🏮 Late January or February — Seollal / Korean Lunar New Year (설날, Seollal) — Lunar Holiday
Seollal is arguably the most important holiday in the Korean cultural calendar. Celebrated on the first day of the first lunar month, it is a three-day public holiday (the day before, the day itself, and the day after). On this occasion, Korean families travel across the country to their ancestral hometowns in one of the largest mass migrations in Asia — a phenomenon known as minjok daeeodong (민족대이동). Families perform ancestral rites called charye (차례), bow deeply in the traditional sebae (세배) greeting to elders, and enjoy special holiday foods such as tteokguk (떡국), a rice cake soup that symbolizes gaining a year in age. Wearing the traditional hanbok is common, and children receive sebaedon (세뱃돈), money in lucky envelopes, from their elders.
For travelers, note that during the Seollal holidays, many small restaurants and shops may close as owners travel home. Transportation is extremely crowded — book trains and buses months in advance.
✊ March 1 — Independence Movement Day (삼일절, Samiljeol) — National Day + Flag Day
Samiljeol commemorates the March 1st Movement of 1919, one of the earliest and most powerful nonviolent independence demonstrations against Japanese colonial rule. On that day, 33 Korean nationalist representatives publicly read the Declaration of Independence in Tapgol Park in Seoul, sparking nationwide protests that spread across the Korean peninsula. Although Japan suppressed the movement harshly — with thousands killed and tens of thousands imprisoned — the movement is celebrated as a symbol of Korean national spirit and ultimately contributed to the establishment of the Korean Provisional Government on April 13, 1919.
On this day, the Taegeukgi is flown at full mast across the country, and official ceremonies are held at Tapgol Park and other sites. It is both a National Celebration Day and a public holiday.
👧 May 5 — Children’s Day (어린이날, Eorininal)
Children’s Day has been a public holiday since 1975 and is a day dedicated to celebrating the rights, happiness, and wellbeing of children. Its origins trace back to May 1, 1922, when Korean children’s rights activist Bang Jeong-hwan and colleagues organized the first ever Children’s Day celebration, advocating for children’s dignity in a time of colonial hardship. The holiday is celebrated with family outings, theme park visits, festivals, and gifts. Many museums, amusement parks, and cultural venues offer special programs on this day. As a result, popular destinations can be extremely crowded, so planning ahead is strongly advised.
🪔 4th Day of the 4th Lunar Month — Buddha’s Birthday (부처님 오신 날, Bucheonnim Osinnal) — Lunar Holiday
Buddha’s Birthday, also known as Sawol Chopail (사월 초파일), falls on the 8th day of the 4th lunar month. It celebrates the birth of Siddhartha Gautama, the founder of Buddhism, and is one of the most visually spectacular holidays in Korea. In the weeks leading up to this day, thousands of colorful lanterns are hung along the streets and temple paths throughout the country. The most famous event is the Yeon Deung Hoe (연등회) — the Lotus Lantern Festival — held in Seoul, which is now registered as a UNESCO Intangible Cultural Heritage. Buddhist temples welcome visitors of all faiths for free meals, meditative programs, and lantern-making activities. This is a wonderful holiday for travelers to experience.
🎖️ June 6 — Memorial Day (현충일, Hyeonchung-il) — Flag Day (Half-Mast)
Memorial Day honors the soldiers, independence fighters, and civilians who gave their lives in service to South Korea, particularly those who died during the Korean War (1950–1953). A national commemoration ceremony is held at the Seoul National Cemetery in Dongjak-gu and the Daejeon National Cemetery, attended by the President of the Republic. At 10:00 AM, a nationwide siren sounds for one minute of silence observed across the country. On this day, the Taegeukgi is flown at half-mast — the only official holiday on which the flag is lowered — as a sign of mourning and respect. While shops are generally open, Koreans are encouraged to observe quiet reflection.
📜 July 17 — Constitution Day (제헌절, Jeheonjeol) — National Day + Flag Day (but NOT a day off)
Constitution Day celebrates the proclamation of the Constitution of the Republic of Korea on July 17, 1948 — the legal foundation of the modern South Korean democratic state. It is one of five National Celebration Days and is designated as a national flag-raising day, meaning the Taegeukgi should be flown. However, since 2008, Constitution Day is no longer a public holiday — meaning schools and most businesses remain open. Many foreigners are surprised to see flags raised on what appears to be a normal working day. This is an important distinction between a “national day” and a “public holiday.”
🌟 August 15 — Liberation Day (광복절, Gwangbokjeol) — National Day + Flag Day
Liberation Day is one of the most emotionally significant days in South Korean history. It marks August 15, 1945, the day Korea was liberated from 35 years of Japanese colonial rule (1910–1945) following Japan’s surrender in World War II. On the same date in 1948, the formal government of the Republic of Korea was officially established. The word Gwangbok (광복) means “restoration of light,” symbolizing the return of Korean sovereignty and freedom. It is a deeply patriotic holiday, and the Taegeukgi is displayed with great pride from virtually every home, building, and lamppost across the country. Official ceremonies, cultural performances, and public events are held nationwide.
🌾 15th Day of the 8th Lunar Month — Chuseok / Korean Harvest Festival (추석, Chuseok) — Lunar Holiday
Chuseok, also called Han-gawi (한가위), is the Korean equivalent of Thanksgiving and is celebrated as a three-day public holiday. Falling on the 15th day of the 8th lunar month — the night of the harvest full moon — Chuseok is a time for families to reunite, visit ancestral graves for a ritual called beolcho (벌초) and seongmyo (성묘), and perform charye (차례) ancestral rites. Traditional foods include songpyeon (송편), half-moon shaped rice cakes stuffed with sesame, red bean, or chestnuts, and a rich variety of seasonal fruits and dishes. Traditional folk games such as ganggangsullae (강강술래 — circle dancing under the moonlight) and ssireum (씨름 — Korean wrestling) are also practiced. For travelers, Chuseok is a magical time to witness Korean family culture, but be aware that many businesses, including restaurants and shops, may close for the full three days.
🌄 October 3 — National Foundation Day (개천절, Gaecheonjeol) — National Day + Flag Day
Gaecheonjeol, meaning “Heaven-opened Day,” commemorates the legendary founding of Gojoseon — the first Korean state — by the mythical figure Dangun in 2333 BC, according to the Samguk Yusa (a 13th-century chronicle). While historians debate the literal historicity of Dangun, the day is celebrated as a symbol of Korean national identity and cultural origins. According to legend, Dangun established his kingdom on the 3rd day of the 10th lunar month, but the holiday is now observed on October 3 of the Gregorian calendar for practical convenience. The Taegeukgi flies across the nation, and the official ceremony is held at Chamseongdan Altar on Manisan Mountain on Ganghwa Island.
🔤 October 9 — Hangul Day (한글날, Hangeulnal) — National Day + Flag Day
Hangul Day commemorates the invention and proclamation of Hangul — the unique phonetic writing system of the Korean language — by King Sejong the Great in 1443, officially proclaimed to the public in 1446. Hangul is celebrated not only for its ingenious scientific design (it was invented with the explicit goal of teaching the common people to read) but also as a cornerstone of Korean cultural identity and pride. King Sejong is widely regarded as the greatest ruler in Korean history. This day became the 5th National Celebration Day in 2005. On Hangul Day, exhibitions, calligraphy events, and cultural programs are held in museums and public spaces. The Taegeukgi is raised throughout the country.
🎄 December 25 — Christmas (크리스마스 / 성탄절, Seongtanjeol)
Christmas is an official public holiday in South Korea, reflecting the significant Christian population (approximately 25–30% of the total). It is commonly called Seongtanjeol (성탄절, “Birth of the Holy Day”) in Korean. While it carries its religious significance, Christmas in Korea also has a strong romantic and commercial character — it is commonly celebrated as a couple’s holiday, with shopping, decorations, and festivities in the city. Major areas like Myeongdong and Gangnam are beautifully lit with Christmas decorations for the entire December season.
🗳️ Election Days
Under South Korean law, certain election days are designated as public holidays. Specifically, the regular presidential election, the National Assembly (legislative) election, and local government elections held at the end of the official term are all considered public holidays. Election days are always held on a Wednesday. This applies only to regular scheduled elections, not by-elections or unscheduled elections. When an election day holiday is on the calendar, it is important for employers to allow workers their voting time off.
🚩 When to Fly the Taegeukgi — National Flag Raising Days
One of the most striking visual experiences in South Korea is seeing the Taegeukgi (태극기) — the red, blue, and black national flag on a white background — hanging from nearly every home and building on certain holidays. The display of the Taegeukgi is governed by the National Flag Law (국기법). Citizens are strongly encouraged, and in some public contexts required, to fly the flag on officially designated National Flag Raising Days (국기 게양일).
The official flag-raising days are as follows:
- March 1 — Independence Movement Day → Full mast (National Day)
- June 6 — Memorial Day → Half-mast (mourning)
- July 17 — Constitution Day → Full mast (National Day, flag raised even though it’s not a day off)
- August 15 — Liberation Day → Full mast (National Day)
- October 1 — Armed Forces Day → Full mast (not a day off, but a flag day)
- October 3 — National Foundation Day → Full mast (National Day)
- October 9 — Hangul Day → Full mast (National Day)
If you see flags on buildings but cannot find a holiday listed on the standard calendar, it may be Constitution Day (July 17) or Armed Forces Day (October 1), both of which are flag-raising days but not official days off.
📅 What Is the Substitute Holiday System (대체공휴일, Daechae Gonghyuil)?
One of the most practical things to understand about Korean holidays — especially for travelers or expats managing work schedules — is the Substitute Holiday System (대체공휴일제도, Daechae Gonghyuil Jedok).
The logic is straightforward: if an official public holiday falls on a Saturday or Sunday (already a non-working day), workers and students would “lose” that day off. To prevent this, South Korea designates the next available weekday (typically Monday) as a substitute public holiday. This means employees receive an equivalent day off to compensate.
This system was first introduced in 2014 for Seollal, Chuseok, and Children’s Day, and was significantly expanded in 2021 to cover all public holidays that fall on weekends, including Liberation Day, National Foundation Day, Hangul Day, and Christmas. The expansion was further broadened in 2023 when Labor Day (May 1) was officially added as a public holiday subject to the substitute holiday rule.
How the system works in practice:
- If a holiday falls on Sunday, the following Monday becomes a substitute holiday.
- If a holiday falls on Saturday, the following Monday is a substitute holiday.
- In rare cases where multiple holidays overlap, the substitute extends further — the first non-holiday weekday afterward is used.
As a practical example: in 2026, National Foundation Day (October 3) falls on a Saturday, so Monday, October 5 becomes a substitute public holiday. This is extremely important for both employers (who must legally treat substitute days as paid holidays) and travelers (who should expect crowded transport and closed offices on these days).

💡 Practical Tips for Foreigners During Korean Holidays
Understanding the holiday calendar in advance will save you enormous headaches during your time in Korea. During the major three-day holidays of Seollal and Chuseok, expect significant disruption to public life. Train tickets sell out weeks in advance, expressways are jammed nationwide, and many small local restaurants and family-owned shops close entirely. Larger supermarkets, convenience stores (편의점), department stores, and tourist attractions, however, generally remain open.
During flag-raising holidays, if you are staying in a residential area, you may notice neighbors hanging the Taegeukgi from their windows — this is a wonderful opportunity to show solidarity with the local community and a sign of national pride. You can purchase a Taegeukgi at any convenience store or large supermarket for a small price.
Finally, for anyone planning business activities in Korea, it is essential to check both the official public holidays and any applicable substitute holidays in your planning year, as even a single unexpected public holiday can disrupt meetings, contracts, and deliveries.
Conclusion:
South Korea’s public holiday calendar is a rich tapestry of history, tradition, lunar cycles, and national pride. From the deeply moving ceremonies of Independence Movement Day and Memorial Day to the joyful family reunions of Seollal and Chuseok, each holiday offers a unique opportunity to understand what makes Korean culture so vibrant and resilient. Whether you are flying the Taegeukgi alongside your Korean neighbors on Liberation Day, joining the Lotus Lantern Festival procession on Buddha’s Birthday, or simply enjoying a long weekend created by the substitute holiday system, these days are an invitation to connect more deeply with one of Asia’s most fascinating nations.
