Public Holidays (공휴일): Korea's Red Days & National Commemorations

If you've ever tried to book a train to Busan around Chuseok, you know: Korean public holidays are serious business. Tickets sell out weeks in advance. Highways become parking lots. Entire cities empty as people head to their hometowns. The holidays on Korea's calendar aren't just days off — they're pressure valves, migration events, and windows into what the country considers worth remembering.

How the Korean Calendar Works

Korea runs on two calendars simultaneously.

The solar calendar (양력) is the standard Gregorian calendar used for official, business, and most daily purposes. Most public holidays are fixed to specific dates on this calendar.

The lunar calendar (음력) is the traditional East Asian calendar based on lunar cycles. Some of the most important Korean holidays — including Chuseok and Seollal — fall on lunar calendar dates, which means their solar calendar equivalents shift by weeks from year to year.

Tip — Why the date keeps changing: If you're trying to plan around Chuseok or Seollal, look up the specific year. Chuseok always falls on the 15th day of the 8th lunar month — but that could be in September or October depending on the year. Government and tourism websites publish the solar equivalents annually.

National Holidays (공휴일)

Korea has 15 official public holidays. When a holiday falls on a Sunday, the following Monday is designated as a substitute holiday — a relatively recent policy that has made Korean workers modestly happier.

설날 — Seollal (Lunar New Year)

When: 3 days around the first day of the lunar calendar (late January–February)

The biggest holiday in Korea. Families travel from across the country to their ancestral homes, perform ancestral rites (차례, charye), share traditional foods, and exchange deep bows (세배, sebae) with elders in exchange for money in decorative envelopes (세뱃돈, sebaedon).

The practical reality: transportation across the country becomes extraordinarily difficult in the days surrounding Seollal. The government publishes exact dates months in advance; booking anything involving travel requires planning well ahead.

Traditional food includes 떡국 (tteokguk) — rice cake soup, which is said to add a year to your age when eaten. This connects to the traditional Korean age system, in which everyone gains a year on Seollal rather than on their birthday.

설날 연휴 (Seollal holiday period)

The day before, Seollal itself, and the day after are all public holidays — giving a 3-day official period, often extended into a longer break with adjacent weekends.

추석 — Chuseok (Korean Thanksgiving)

When: 3 days around the 15th of the 8th lunar month (September–October)

If Seollal is the winter equivalent, Chuseok is its autumn counterpart — and equally significant. It's a harvest festival with ancestral rites, family gatherings, and the sharing of traditional foods. The signature food is 송편 (songpyeon), half-moon shaped rice cakes filled with sesame, beans, or chestnuts, traditionally made together as a family the night before.

Chuseok and Seollal together account for the two largest human migration events in Korea every year. The traffic and transportation situation around both holidays is genuinely extraordinary.

삼일절 — March 1st Independence Movement Day

When: March 1

Commemorates the March 1st Movement of 1919, when Koreans staged nationwide peaceful protests against Japanese colonial rule. The Declaration of Independence was publicly read in Seoul's Tapgol Park on this day. Thirty-three representatives had signed it; many were subsequently arrested, tortured, or killed. The day is a somber reminder of the colonial period and a celebration of Korean resilience and national identity.

어린이날 — Children's Day

When: May 5

Established in 1923 by independence activist Bang Jeong-hwan as a day to recognize the rights and happiness of children. Now one of Korea's most cheerful public holidays — theme parks, zoos, and family entertainment venues are packed. Parents feel considerable social pressure to make the day special for their children.

어버이날 — Parents' Day

When: May 8 (not a public holiday, but widely observed)

Not technically a day off, but culturally significant — children give carnations to their parents and grandparents. The contrast with Children's Day (a full public holiday) is sometimes noted as reflecting Korean Confucian values: children are celebrated, but so are the parents who raised them.

부처님 오신 날 — Buddha's Birthday (Lotus Lantern Festival)

When: 4th month, 8th day of the lunar calendar (April–May)

A national holiday celebrating the birth of Buddha. The most visible public event is the Lotus Lantern Festival in Seoul — hundreds of thousands of paper lanterns carried through the streets of Jongno in an evening procession. Even for non-Buddhists, it's one of the most visually spectacular events in the Korean calendar.

현충일 — Memorial Day

When: June 6

A day of national commemoration for soldiers and civilians who gave their lives for the country, particularly in the Korean War (1950–1953). At 10:00 AM, a national siren sounds across the country for one minute of silence. It's one of the most solemn moments on the Korean calendar — and a reminder that the Korean War, though often called the "Forgotten War" in the West, is very much present in Korean national consciousness.

광복절 — Liberation Day

When: August 15

Marks Korea's liberation from Japanese colonial rule on August 15, 1945, following Japan's surrender in World War II. One of the most politically charged holidays on the calendar — sentiments about Japan, about national identity, and about unresolved historical issues tend to surface publicly around this date. Also the day the Republic of Korea was officially established in 1948.

개천절 — National Foundation Day

When: October 3

Commemorates the legendary founding of the first Korean kingdom — Gojoseon — by Dangun in 2333 BCE according to tradition. The date is more mythological than historical, but the holiday carries real cultural weight as an expression of Korean national origins and continuity.

한글날 — Hangul Day

When: October 9

Celebrates the proclamation of Hangul, the Korean alphabet, by King Sejong in 1446. It's one of the few holidays in the world dedicated to an alphabet — a sign of how central the script is to Korean national identity. Hangul is considered one of the most scientifically designed writing systems ever created; its invention and adoption are points of genuine pride.

크리스마스 — Christmas

When: December 25

Korea is home to a significant Christian population — roughly 30% of the country identifies as Protestant or Catholic — and Christmas is a public holiday. It's widely celebrated beyond the Christian community as well, with Seoul's Myeongdong shopping district lit up through December and Christmas Eve being a major date night.

A Note on the Holidays You Won't Find Here

Some significant Korean commemorations are not public holidays:

• April 19 (사일구) — anniversary of the 1960 student revolution that ousted President Syngman Rhee

• May 18 (오월 광주) — anniversary of the 1980 Gwangju Uprising, a democratic protest violently suppressed by the military government

• November 11 — Pepero Day, a commercially driven but widely observed day for exchanging chocolate-covered cookie sticks (think Valentine's Day, minus the official recognition)

Tip — Holidays and business: Most shops, restaurants, and entertainment venues stay open on Korean public holidays — sometimes with reduced hours. Major exceptions: banks, government offices, and many smaller family-run businesses close for Seollal and Chuseok. Plan around those two if you need official services.
