Seoul Events and the Dates That Change a Trip

A Seoul events calendar matters less for the festivals than for the four or five dates that close things — Chuseok, Seollal, the palace night seasons and the quarterly museum closures. This page lists both, with the 2026 dates where they are published, checked in Q3 2026. The rest of the trip is on the Seoul city guide homepage.

Quick answer Four dates that close things, and three worth planning for

Seoul's festival calendar is busy, but only a handful of dates actually change what a visitor can do. The two lunar holidays close museums for a day and pause palace programmes. The first Monday of four months closes the National Museum's permanent halls. And in the other direction, the palace night seasons, the lantern weeks before Buddha's birthday and the autumn foliage fortnight are worth building a trip around.

Key takeaways

  • ⚠ Chuseok 24–27 September 2026 and Seollal in late winter: national museums shut on the day, palace special viewings pause.
  • ⚠ The National Museum of Korea's permanent halls close the first Monday of March, June, September and December.
  • Culture Day, the last Wednesday of each month, extends hours at many institutions — the best free evening in the month.

The Dates That Change a Trip

What happens on each, from the palace and museum calendars, checked in Q3 2026. Lunar dates move each year; the 2026 ones are given where published.

When What Effect on a visit
Seollal, lunar new year Family holiday National museums close for the day; palaces run reduced programmes; intercity travel impossible
Buddha's birthday, May Lantern season for weeks beforehand Jogyesa hung with lanterns; a parade through central Seoul; free
Last Wednesday monthly Korea's Culture Day Extended museum hours and reduced prices; the Folk Museum to 21:00
24–27 September 2026 Chuseok Museums closed on the day; Gyeongbokgung special viewings suspended for the block; city empties
2 September – 2 October 2026 Gyeongbokgung night viewing 19:00–21:30, last entry 20:30, closed Mondays and Tuesdays
Late October – early November Autumn foliage The busiest weeks of the Korean travel year; book early
First Monday of Mar, Jun, Sep, Dec Museum maintenance National Museum of Korea permanent halls closed; building open

Lunar-calendar dates — Seollal, Buddha's birthday, Chuseok — move each year. The fixed-day rules, such as the first-Monday closures and Culture Day, do not.

The Palace Night Seasons

The most interesting things in Seoul's calendar are run by the Korea Heritage Service at the palaces, and they are seasonal rather than permanent.

Gyeongbokgung night viewing — an ordinary ticket, the palace lit, running 2 September to 2 October 2026 from 19:00 to 21:30 with last entry at 20:30, closed Mondays and Tuesdays.

Byeolbit Yahaeng, the star-light night tour — a small guided programme with its own reservation, 2 September to 24 October 2026 at 18:30 and 19:40, Wednesday to Sunday, with no sessions 30 September to 4 October and foreigner-only sessions 21 to 24 October.

Saenggwabang, the royal tea sitting — 2 September to 26 October at 10:00, 11:40, 14:00 and 15:40 on open days, by reservation.

Gyeonghoeru and Hyangwonjeong special viewing — the only way inside the banquet pavilion, running to 30 October on Wednesdays and Fridays only, suspended over Chuseok and on 9 October.

Spring seasons run on a similar pattern from around April. All of them are booked through the palace's own reservation system rather than through resellers. The palace page carries the current set.

The Festivals Worth Timing For

The lantern season, in the weeks before Buddha's birthday in May. Jogyesa's courtyard is roofed with thousands of paper lotus lanterns and a large parade runs through central Seoul. It lasts weeks, it is free, and it is the best-looking thing in the Seoul year.

Autumn foliage, late October into early November — not a festival but the busiest travel period in Korea, and the reason the Huwon garden and every hotel book out.

The Seoul Lantern Festival on Cheonggyecheon in November, when illuminated figures are floated along the stream.

Fireworks on the Han, in early October, which puts several hundred thousand people on both banks of the river.

Seoul Light at DDP, a winter media-art projection onto the building's skin.

Dates for all of these are published a few months ahead rather than a year, so check before building a trip around one. What does not move is the shape of the year: spring and autumn are event-dense, summer is quiet, winter is indoors.

Calendar Questions

What are the main holidays in Korea?

Seollal, the lunar new year, in late winter, and Chuseok in autumn — 24 to 27 September in 2026. Both close the national museums for the day and pause palace special programmes, and both make intercity travel impossible to book.

When is the lantern festival in Seoul?

The lotus lantern season runs for weeks before Buddha's birthday in May, centred on Jogyesa, with a parade through central Seoul. The separate Seoul Lantern Festival floats illuminated figures on Cheonggyecheon in November.

Can I visit the palaces at night?

During the published seasons. Autumn 2026 night viewing at Gyeongbokgung runs 2 September to 2 October, 19:00–21:30, closed Mondays and Tuesdays. Deoksugung and Changgyeonggung stay open to 21:00 all year.

What is Culture Day in Korea?

The last Wednesday of each month, when many cultural institutions extend their hours or reduce prices. It is the best free evening in the month for a visitor.

Should I avoid Chuseok?

Not necessarily — the city empties and is pleasant. But museums close on the day, palace special viewings pause for the block, and trains and buses out of Seoul are fully booked.

When is the busiest time in Seoul?

Late October into early November, which is Korea's own travel peak as well as the international one. Book everything early.
